A Distriсt Court judge found probable cause on a complaint alleging that the defendant “did conspire with Philip A. DeMarco to violate the provisions of G. L. c. 94C [Controlled Substances Act], to wit: Distribution of Heroin, in violation of G. L. c. 94C, § 40.” A grand jury subsequently indicted the defendant. The indictment stated that, “Jose Cantres did conspire with Philip DeMarco to violatе the Controlled Substance Act.” The specific violation of the Controlled Substances Act contemplated by the conspiracy was not specified. After discovery, including the Commonwealth’s furnishing the defendant with relevant police reports and a tape recording of the probable cause hearing, the case was tried before a judge without a jury. On the day of the trial, the defendant orally requested a bill of particulars. That request was denied. At the close of the Commonwealth’s case, and again at the close of all the evidence, the defendant moved for a required finding of not guilty. On each occasion, the motion was denied. The defendant was found guilty and was sentenced to a term of from eight to ten years at the Massachusetts Correctional Institution at Cedar Junction. He now appeals the conviction. We transferred the appeal to this court on our own motion. We affirm.
Article 12 of the Massachusetts Declaration of Rights provides that “[n]o subject shall bе held to answer for any crimes or offence, until the same is fully and plainly, substantially and formally, described to him . . . .” The defendant claims that he was denied his rights under art. 12 because the indictment did not allege the specific substantive violation of c. 94C that he was charged with conspiracy to commit and, in addition, his motion for particulars was deniеd. The defendant claims that he was neither put on notice of what he had done nor of the sentence that might be imposed on him.
It is true, as the defendant argues, that, “[i]f an indictment fails to allege any fact necessary to constitute an offence, even statutory, it is defective.”
Commonwealth
v.
Bracy,
In
Commonwealth
v.
Soule,
The defendant argues that
Commonwealth
v.
Soule, supra,
does not control this case because in
Soule,
unlike here, the Commonweаlth filed a bill of particulars. It is clear, however, that the Appeals Court did not reason in
Soule
that the particulars filed there elevated a defective indictment to a valid one. Particulars cannot save a defective indictment.
Commonwealth
v.
Ries,
A timely request for particulars is an appropriate way to generate notice with respect to the substantive violation contemplated by the conspiracy and therefore the precise sentence exposure. Indeed, G. L. c. 277, § 38 (1986 ed.), provides: “In a prоsecution under any provisions of chapter ninety-four C, for unlawfully manufacturing, dispensing or distributing a controlled substance ... the defendant shall be entitled to a bill of particulars.” It is unclear whether the defendant argues that, even if the indictment met constitutional requirements, the indictment should nevertheless be dismissed because his motion for particulars was denied. If such an argument is made, we reject it for several reasons. Since the indictment was valid, the absence of particulars is not jurisdictional. The defendant did not move in the trial court for dismissal of the indictment. It is too late, except on jurisdictional grounds, to seek dismissal for the first time in this court. Furthermore, G. L. c. 277, §38, does not literally аpply to prosecutions for conspiracy. In addition, it is questionable whether § 38 should be construed as entitling a defendant to particulars when the first request therefor is not made until the day of trial. In any event, even if
*242
the judge’s denial of the defendant’s last minute request for particulars be deemed erroneous, the error was harmless. As a result of the pretrial discovery described above, the defendant was fully aware before trial that the thrust of the Commonwealth’s case would be what it turned out to be, namely, that the defendant and DeMarco conspired to distribute heroin. See
Commonwealth
v.
Baker,
The defendant’s next argument on appeal is that the trial judge erred in failing to apply “Whаrton’s Rule.” Wharton’s Rule provides “that an agreement by two persons to commit a particular crime cannot be prosecuted as a conspiracy when the crime is of such a nature as necessarily to require the participation of two persons for its commission.”
Commonwealth
v.
Schoening,
Even if it is generally applicable in the Commonwealth, Wharton’s Rule has “vitality only as a judicial presumption, to be applied in the absence of legislative intent to the contrary.”
Iannelli
v.
United States,
We may apply the same analysis to the construction of the Massachusetts statute. General Laws c. 94C, § 40, makes it a crime to conspire with another “to violate
any
provision of [the Controlled Substances Act]” (emphasis аdded). Thus, we may presume that the Massachusetts Legislature “was equally as concerned about the special dangers that conspiracies to distribute controlled drugs pose to [Massachusetts] citizens as was Congress with respect to the federal statute.”
State
v.
Erickson,
Finally, the defendant argues that the Commonwealth failed to prove his intent, and therefore agreеment, to commit the object crime, distribution of heroin, because there was insufficient evidence to prove beyond a reasonable doubt that the substance delivered by the defendant to DeMarco was actually heroin. He contends, therefore, that the judge improperly denied his motion, and his renewed motion, for a rеquired finding of not guilty. The defendant’s argument is constructed on the incorrect premise that, in order to prove conspiracy to distribute heroin, it was necessary for the Commonwealth to introduce evidence that the substance actually delivered by the defendant to DeMarco pursuant to the conspiracy was heroin. The Cоm
*244
monwealth’s case might have been strengthened had it been able to show that the delivered substance was heroin, but it was not required to do so. “The heart of a conspiracy is the formulation of the unlawful agreement or combination.
Attorney Gen.
v.
Tufts,
“A conspiracy may be proved by circumstantial evidence, and this is the usual mode of proving it, since it is not often that direct evidence can be had. The acts of different persons who are shown to have known each other, or to have been in communication with each other, directed towards the accomplishment оf the same object, especially if by the same means or in the same manner, may be satisfactory proof of a conspiracy.”
Commonwealth
v.
Beneficial Fin. Co.,
The evidence in this case bearing on the earlier repeated and interrelated conduct of the defendant and DeMarco was sufficient to warrant a finding beyond a reasonablе doubt that the defendant conspired with DeMarco to distribute heroin. DeMarco testified, frequently over objection, as follows: On February 18, 1987, he went to Shaughnessy Terrace in Lowell to purchase heroin. He was a heroin addict at that time and had purchased heroin there many times before. He had purchased heroin from the dеfendant on at least ten previous occasions between the end of 1986 and February 18,1987. The heroin was *245 always wrapped in different colors of plastic and DeMarco would pay $30 for each “bag.” After he purchased the heroin, he would “shoot it” and “get high.” He experienced the same physical reaction from using the substаnce he bought from the defendant on prior occasions as he had experienced from using other “articles” which he believed were heroin, and which he bought from other people. When asked how many times he purchased substances which he believed to be heroin and how many times he experienced the feeling hе expected from using that substance, he replied, “[tjhousands.”
DeMarco testified that, on the date in question, he got out of his automobile, approached the defendant, and asked him how many bags he had left. The defendant told him he had two bags. DeMarco then gave the defendant $60, and the defendant handed DeMarco what DeMаrco believed to be two bags of heroin. They were packaged in olive green plastic. DeMarco then testified that he returned to his automobile, which was driven away by another person. DeMarco stated that five minutes later he noticed a police car behind him, at which time he placed the two plastic bаgs in his mouth and swallowed them. He said that the vehicle was then in an accident, after which he was arrested and charged with conspiracy to possess heroin. He subsequently pleaded guilty to that charge. By his own admission, DeMarco never “shot up” the substance he bought that day, nor did he get any reaction from having swallowed the bags. The plastic bags remained sealed and passed from his body about five days later.
In
Commonwealth
v.
Dawson,
On appeal, the defendant argues only that (1) the judge failed to make the type of finding required by
Dawson,
and (2) there was no evidence that DeMarco “used” the substance distributed to him by the defendant pursuant to the alleged conspiracy. We are not persuaded by the defendant’s arguments. Assuming that the defendant adequately objected at trial to the admissibility of DeMarco’s testimony concerning a pattern of dealings between DeMarco and the defendant in heroin, a matter not made entirely clear by the rеcord, the judge’s allowance of the testimony implies a prior determination by him that the witness’s experience qualified him to characterize the subject of those transactions as heroin.
Commonwealth
v.
Baker,
Judgment affirmed.
