The defendant appealed from a judgment of the Superior Court rendered September 13,1974, on a jury verdict of guilty returned on an information charging him with three counts of selling cocaine in violation of 1973 Public Acts, No. 73-681, §26 (a) (General Statutes §19-480 [a]), and one count of controlling cocaine in violation of 1972 Public Acts, No. 278, § 26 (a) (General Statutes §19-481 [a]). He was sentenced to the correctional institution at Somers for an effective term of not less than ten years nor more than twenty years. Although in his preliminary statement of issues the defendant made numerous claims of error, he has briefed only two of them, asserting that the court erred in refusing to charge the jury on entrapment and in admitting the testimony of a toxicologist concerning the analysis of substances which the state claimed were cocaine. The claims of error which have not been briefed are considered abandoned.
State
v.
Crawford,
There was evidence from which the jury could have found the following facts: Charles Walkley worked as an undercover narcotics agent for the southwest regional crime squad from September, 1973, through April, 1974. On March 30,1974, after reporting to headquarters in Bridgeport, he drove to Stamford at approximately 10:30 a.m. to buy narcotics. He arrived at the Duchess Restaurant at *433 about 12:30 p.m. and met with Melvin Collins, whom he had previously known. Stamford police officer Michael Moon was covering him. After a discussion with Collins about purchasing narcotics, Walkley then met the defendant, Perry Hawkins, Jr. Walk-ley had never met or seen the defendant before. Walkley and the defendant were in Walkley’s automobile in the presence of Collins conversing about narcotics sales when Walkley told the defendant that he understood the defendant could find some cocaine for him. The defendant said he could and Walkley agreed to buy $75 worth. Pursuant to instructions from the defendant, Walkley drove to 20 Orchard Street in Stamford. When the three men arrived there, the defendant left the ear, entered the house and returned saying that it would be a few minutes because his sister was packaging it. The defendant again left the car and returned with a tinfoil packet containing a white powder substance. After observing the contents of the packets, Walkley paid the defendant $75. Walkley then drove back to the Duchess Restaurant, taking with him the defendant and Collins. Before the defendant left Walkley, he asked him if he would be back for more. Walkley said he would get in touch with the defendant if the “coke” was good. The defendant then wrote his phone number on a piece of paper for Walkley. Later the same day, Walkley met with covering officer Moon and examined several photographs Moon had brought with him. Walkley selected a photograph of the defendant as the man from whom he had purchased the narcotics earlier in the day.
Walkley subsequently, by arrangement, met with the defendant on two additional days, April 1, 1974, and April 3, 1974, and on each occasion purchased cocaine from him.
*434 The evening before the second transaction on April 1, 1974, Walldey telephoned the defendant at the number the defendant had given him and arranged to meet the defendant the next morning in front of the Duchess Bestaurant. Walldey’s examination of the Southern New England Telephone Company book revealed that the number he had been given was listed to 20 Orchard Street in Stamford. When they met, the defendant entered Walkley’s car, and Walkley expressed his interest in making another identical purchase. Walkley, again covered and observed by Officer Moon, followed the defendant’s car to Orchard Street. En route, the cars were joined by a car driven by the defendant’s sister, Patricia Parham. Walkley parked his car and waited while the defendant and his sister entered the house together. The defendant came out shortly, explaining that it would be a few moments. He, thereafter, returned and gave Walkley the cocaine in exchange for $83 telling Walkley to contact him should he want more.
The third transaction occurred on April 3, 1974. Walkley called the number previously given to him and discussed a $75 purchase with the defendant. The defendant declined to go and meet Walkley stating that Walkley could come right to his house and pick up the merchandise. Walkley drove to Orchard Street, again covered by Officer Moon. There the defendant handed Walkley a foil packet containing cocaine in exchange for $75.
After each transaction, Walkley returned to Bridgeport where he field tested and processed the contents of the packets he had purchased from the defendant which were then transmitted to the state toxicological laboratory where, upon analysis, they were each found to contain cocaine.
*435
The defendant’s first claim is that the court erred in refusing to charge the jury on the law of entrapment, although the defendant filed a request for such a charge. In
State
v.
McNally,
Under our former practice, where findings were necessary in appeals in jury cases it was incumbent upon the parties to file claims of proof with appropriate references to pages of the transcript. (1963 Practice Book §§ 629—631; Form 603). In
State
v.
DaVila,
The defendant’s remaining claim of error — that the court erred in admitting the testimony of Charles N. Reading, a toxicologist employed by the state department of health, that the substances which the defendant sold to Officer Walkley were cocaine — requires but brief comment. While the present appeal was pending, we decided the case of
State
v.
Reardon,
There is no error.
In this opinion the other judges concurred.
Notes
"[General Statutes] See. 53a-15. entrapment as defense. In any prosecution for an offense, it shall be a defense that the defendant engaged in the proscribed conduct because he was induced to do so by a public servant, or by a person acting in cooperation with a public servant, for the purpose of institution of criminal prosecution against the defendant, and that the defendant did not contemplate and would not otherwise have engaged in such conduct.”
