Appeal by defendant Mary Penny from a judgment of conviction of involuntary manslaughter.
Defendant was charged with a violation of section 192, subdivision 2, of the Penal Code. That section provides that manslaughter is the unlawful killing of a human being, without malice. “2. Involuntary—in the commission of an unlawful act, not amounting to felony; or in the commission of a lawful act which might produce death, in an unlawful manner, or without due caution and circumspection; provided that this subdivision shall not apply to acts committed in the driving of a vehicle,.”
For seven years defendant had been engaged in “face rejuvenation” in the city of Los Angeles. It is conceded *864 that she had no license from either the Cosmetology Board or the Medical Board of this state; she did have a business license from the city of Los Angeles for the business of “Pаce Rejuvenation.”
Defendant had a year’s training with a Madame Bergeron (now deceased) in Los Angeles and approximately three months’ training with one Geraldine Gorman in New York. In New York, she received the formula which she used in her work. The formula consisted of one ounce of water, a heaping tablespoon of resorcinol (of the same chemical group) and 16 drops of phenol (carbolic acid).
Kay Stanley, the victim, had consulted with defendant some seven months earlier about having her face treated to remove wrinkles and pock marks, but did not have the money to do it at that time. Around Easter time of 1953, she again asked defendant to treat her face, but defendant was to be away and could not do it then. On the morning of May 4, 1953, Kay Stanley arrived at about 10 in the morning аt defendant’s home where she was to stay during the treatment. Kay’s face was first washed with warm water and soda; the formula was then applied with a cotton wrapped wooden applicator to Kay’s cheeks, a square inch at a, time. After each application, the area was pressed with sterile gauze to remove excess moisture. The entire forehead was covered as well as the eyelids, the process taking about two hours. The treated area was then covered with gauze and taped with small pieces of tape which overlapped and covered the area; regular waterproof adhesive tape was then put on over the other tape; this formed a mask over the upper portion of the patient’s face. After the taping had been completed, Kay walked to an adjoining room where she had lunch, listened to the radio and looked at magazines. At approximately 6 in the evening, defendant proceeded to treat the lower half of Kay’s face in the same manner as she had treated the upper portion which took about three quarters of an hour. .When the treatment was completed, Kay asked defendant if she could sit up for awhile before the taping was started; she sounded sleepy. The defendant told her she could and said she would get her a glass of water. When defendant returned with the water, Kay said, “I feel a little bit faint” and lay back as though in a faint. Defendant asked her how she felt but received no answer. When defendant tried to lift her she found she was dead weight and felt that she had fаinted. Defendant tried unsuccessfully to call a Dr. Wallace *865 and left a message for Mm; she then called a nurse-anaesthetist who arrived at the house about 10 or 15 minutes later. Mrs. Jevne, the nurse, tried to take the patient’s pulse without success; there was no respiration. She then administered Coramine, a heart stimulant by hypodermic needle, in the arm; she then gave a hypodermic injection of Metrazol, another stimulant; she then tried artificial respiration and caffeine benzoate. She told defendant to call the doctor again. Dr. Wallace arrived about an hour after Mrs. Jevne did and examined the lady whom he found lying on the treatment table. He was able to feel no pulse and there was no respiration. He noticed signs indicating death had existed for some period of time.
Defendant called her attorney who called the police.
The finding, аfter an autopsy had been had, was that the immediate cause of death was phenol (carbolic acid) poisoning and edema of the glottis due to “application of phenol-containing mixture to the face and neck.” Other findings were that 5.1 milligrams of phenol per 100 grams were found in the liver and 2.9 milligrams of phenol per 100 grams were found in the blood of the victim. It was the opinion of Dr. Newbarr, prosecution witness and chief autopsy surgeon for the Los Angeles coroner’s office, that these findings were the result of the application of a solution containing more than 10 per cent phenol to the face and neck of the victim. It was the opinion of Mr. Abernathy, the toxicologist, that the reddish-brown discoloration of the victim’s face was a third degree burn caused by phenol, and that the normal finding of phenol in a normal human being would be practically zero.
There was evidence in the record which showed that the victim had been taking reducing pills prescribed by a Texas doctor; that in order to obtain replacement of the pills, it was necessary for her to have her heart examined and blood pressure taken by a local doctor; that prior to going to the defendant’s home for the face rejuvenation treatment she had had her heart and pulse examined and her blood pressure taken and that all findings were normal.
The defendant testified that when she first received the formula for face rejuvenation she had it analyzed and that it contained only 3.1 per cent phenol. The defense also took the position that the victim may have had an allergy to phenol which was the cause of death. Dr. Newbarr testified for the prosecution and gave, as his opinion, that the solution *866 contained over 10 per cent phenol and that the findings were not consistent with the theory of allergy. Dr. Johnstone testified for the defense and it was his opinion that the solution contained approximately 3 per cent phenol; that when applied to the skin it would not cause death; that all autopsy findings were consistent with the theory that the victim was allergic to phenol. Without going into great detail, it seems sufficient to note that the medical testimony was in direct conflict. Defendant’s argument that the evidence is insufficient to support the judgment insofar as the cause of death is Concerned is without merit. The testimony is ample to show that the victim died of phenol poisoning.
Defendant’s argument that Dr. Newbarr was “allowed” to give an “unsupported and incompetent opinion” that the solution contained more than 10 per cent phenol is also without merit. Dr. Newbarr was found to be qualified by the trial court; his opinion was based on his reading on the subject, his own observation of the victim, and his own previous experiences. The qualifications of an expert witness are for the trial court

v.
Pacific Gas & Elec. Co.,
Instructions
Defendant contends that the following instruction was without basis in the evidence. “Any licensed cosmetologist who applies to any human being a solution of phenol greater than ten per cent is guilty of a misdemeanor.
‘ ‘ This is an unlawful act not amounting to a felony. Business & Professions Code, Section 7415.” (Emphasis added.)
As heretofore pointed out, it is admitted that defendant was not licensed as a cosmetologist.
It is contended that the just quoted instruction was calculated to mislead and confuse the jury when considered with the following instruction: “Every person who engages in, or attempts to engage in, the practice of cosmetology or any branch thereof without a license therefore issued by the *867 State Board of Cosmetology or in an establishment other than one licensed by the State Board of Cosmetology is guilty of a misdemeanor.
“The art of cosmetology includes the beautifying of the face, neck, arms, bust or upper part of the human body, by the use of cosmetic preparations, antiseptics, tonics, lotions or creams.
“A violation of this law is an unlawful act not amounting to a felony.
“Business & Professions Code, Section 7325
“Business & Professions Code, Section 7321(b) [sic] [c].”
It is argued that under these two instructions defendant could have been convicted (1) if the jury believed she used a solution containing more than 10 per cent phenol and had a license; or (2) that she was guilty because she was required to have a license and had none.
There can be no doubt but that the instruction concerning a “licensed” cosmetologist was erroneous and that it had no foundation in the evidence. On the issue of defendant’s guilt, the jury could well have inferred that she was guilty of the crime by reasoning that even a licensed cosmetologist could not use a solution containing more than 10 per cent phenol. So fаr as the second instruction is concerned, it is supported by the evidence and correctly stated the law as it relates to those practicing cosmetology and the persons considered engaged in that practice. It appears to us that as a matter of law, defendant was engaged in the practice of cosmetology and the jury should have been so instructed.

The next question which presents itself is whether defendant’s lack of a license (and the fact that she was, therefore, guilty of a misdemeanor) was the cause of Mrs. Stanley’s death. Section 192.2 of the Penal Code provides that a person is guilty of involuntary manslaughter if a human being is unlawfully killed “in the commission of an unlawful act, not amounting to a felony; ...” The jury was instructed that defendant’s conduct must have been the proximate cause of the death. The People argue that the law requiring licensing of those practicing cosmetology was

Mitchell,
Another question which presents itself is whether defendant was guilty of an unlawful act in applying a solution containing phenol and resorcinol to the human face and neck with the knowledge that both chemicals were poisonous. The statute providing that a licensed cosmetologist may not use a solution containing greater than 10 per cent phenol without being guilty of a misdemeanor sets the standard for licensed persons in that profession or occupation.

Due Caution and Circumspection
„ The second clause of section 192, subdivision 2, of the Penal Code provides that one is guilty of manslaughter if a human being is killed in the commission of a “lawful act which might produce death, in an unlawful manner, or without due caution and circumspection. ...” It has been held that without “due caution and circumspection” is the equivalent of “criminal negligence”

v.
Driggs,
If we assume that a treatment aimed at removing wrinldes from the human face is a “lawful act,” it must next be determined whether such act was one which “might cause death.” Defendant admitted she knew the substances used were poisons; that they were dangerous substances; that their indiscriminate use could be dangerous. Inasmuch as defendant was knowingly using poison in her treatment solution, the jury сould have concluded that her treatment was one which could have caused death.
*870
The jury was also instructed that “The doing of an act ordinarily lawful which results in the death of a human being may be manslaughter where the act, being one which might cause death, is performed in an unlawful manner or without due caution and circumspection. When a person is doing anything dangerous in itself or has charge of anything dangerous in its use and acts with reference thereto without taking those proper precautions which a person of ordinary prudence would have used under the circumstances and the death of another results therefrom, his act or neglect is, a criminal act against the person so killed. ’]J Phe People" contend that these two instructions harmonize with the ease of

v.
Keefer
(1861),
*877 A note in 161 American Law Reports 10, entitled “Homicide Through. Culpable Negligence” seeks to reconcile the California cases. It is suggested (p. 50) that section 20 of the Penal Code provides that “In every crime or public offense there must exist a union or joint operation of act and intent, or criminal negligence”; that section 7, subdivision 2, of the Penal Code provides that “The words ‘neglect,’ ‘negligence,’ ‘negligent, ’ and ‘negligently’ import a want of such attention to the nature or probable consequences of the act or omission as a prudent man ordinarily bestows in acting in his own concerns”; and that these two sections have “perhaps” influenced the California courts’ interpretation of “criminal negligence.” It is pointed out that the general rule is that something more than ordinary negligence is needed to constitute either culpable negligence or criminal negligence under involuntary manslaughter statutes.
Two law review notes (25 Cal.L.Rev. 1; 28 Cal.L.Rev. 518) seek to harmonize the negligent homicide decisions (under the Vehicle Code) with the involuntary manslaughter ones in California. It should be noted that these articles were both written prior to 1945 when the involuntary manslaughter statute was enacted in its present form.
It is pointed out in 28 California Law Review 518, 519, that a review of the available authority of the half century prior to 1872 (when section 20 of the Penal Code was enacted) supports the conclusion that “criminal negligence” had a common law meaning at that time which must be referred to in determining the effect of its inclusion in section 20. The English reports of the period reveal а well established rule that gross negligence is necessary in criminal prosecutions, and that the term “criminal negligence” was used along with many others to characterize the degree of neglect required. It is said that there was nothing to show that the Legislature intended to except section 192 of the Penal Code from the operation of section 20 of the same code. In speaking of
People
v.
Pociask,
In the other note (25 Cal.L.Rev. 1, 30) is found this statement : “The main question is, therefore, what does ‘without due caution and circumspection’ mean; what degree of culpability is required? The law on this point seems in California to be less settled and less clear than in other jurisdictions.” After quoting an instruction identical with the one in the present case except for the words “even though his negligence does not amount to a wanton or reckless disregard of human safety or life” which are not present in our case, the writer notes that “ It is not easy to understand the true significance of this rule. Did the supreme court therein formulate the рroposition that ordinary (civil) negligence would suffice to constitute manslaughter ? Certainly California has widened the concept of criminal negligence necessary to constitute manslaughter further than most of the other jurisdictions. But it does not seem correct to say that the quoted passages from People v. Seiler and People v. Wilson [both automobile-manslaughter eases] are authority for the proposition that the negligence which suffices as the basis for civil liability and the negligence which is the foundation for criminal liability under the manslaughter statute are of the same degree. To be sure the language of the court contains a term which is customarily used in the definition of civil negligence, namely, the following: ‘precautions which a person of ordinary prudence could have used under the circumstances. ’ But as а whole the definition differs from that of ordinary negligence, including, as it does, the element of something dangerous in itself or in its use. Furthermore, the court admitted in the quoted passage from People v. Seiler that the lack of due *879 caution and circumspection might be such as would be defined as culpable, even though this word was not considered to be a proper term to convey the significance of due caution and circumspection. ’ ’
In the two most recently filed civil liability cases before this court
(Jensen
v.
Minard, ante,
p. 325 [
The statute (Pen. Code, § 192, subd. 2) provides (in part) that in order to convict a person of involuntary manslaughter, there shall be an unlawful killing of a human being in the commission of a lawful act which might produce death without due caution and circumspecton. The words lack of “due caution and circumspection” have been hеretofore held to be the equivalent of “criminal negligence” (Pen. Code, § 20). The general rule is set forth in 26 American Jurisprudence, Homicide, section 210, page 299, as follows: “The authorities are agreed, in the absence of statutory regulations denouncing certain acts as criminal, that in order to impose criminal liability for a homicide caused by negligence, there must be a higher degree of negligence than is required to establish negligent default on a mere civil issue. The negligence "must be aggravated, culpable, gross, or reckless, that is, the conduct of the accused must be such a departure from what would be the conduct of an ordinarily prudent or careful man under the same circumstances as to be incompatible with a proper regard for human life, or, in other words, а disregard of human life or an indifference to consequences.” The article continues thus: 1 ‘Aside from the facts that a more culpable degree of negligence is required in order to establish *880 a criminal homicide than is required in a civil action for damages and that contributory negligence is not a defense, criminal responsibility for a negligent homicide is ordinarily to be determined pursuant to the general principles of negligence, the fundamental of which is knowledge, actual or imputed, that the act of the slayer tended to endanger life. The facts must be such that the fatal consequence of the negligent act could reasonably have been foreseen. It must appear that the death was not the result of misadventure, but the natural and probable result of a reckless оr culpably negligent act. ’ ’
We hold, therefore, that the general rule just quoted, sets forth the standard to be used in California for negligent homicide (Pen. Code, § 192, subd. 2) in other than vehicle cases. Defendant here was charged with a violation of section 192, subdivision 2, of the Penal Code. The jury should have been instructed according to the rule which generally prevails in this country as to what constitutes criminal negligence, or lack of due caution and circumspection so that her guilt or innocence might be determined in accord therewith.
Because of the errors heretofore noted, the judgment is reversed.
