On a trial to the jury the defendant was found guilty of violating the State Narcotic Drug Act when оn June 7, 1968, in the city of Stamford, he unlawfully sold heroin to Frank Guzman, an undercover agent fоr the bureau of narcotics and dangerous drugs, in violation of §§ 8 and 36 (a) of Public Acts 1967, Nо. 555, now General Statutes §§ 19-452 and 19-480 (a) as amended. On March 14, 1969, the court sentenced thе defendant to not *515 less than seven nor more than ten years in the Connecticut Cоrrectional Institution at Somers. In this appeal from the judgment rendered, the sole issue raised by the defendant is whether the court erred in permitting the state to withhold the name of the informer who was present at the scene of the crime charged.
During cross-examination, defense counsel 1 asked Edward McNulty, a member of the Stamford police department, with whom wаs Guzman, an agent for the bureau of narcotics and dangerous drugs, at the time of thе heroin sale. McNulty replied: “With an informant.” Defense counsel asked: “Could I please have the name?” The assistant state’s attorney then stated: “Objection, yоnr Honor,” to which the court replied: “Sustained.” The defendant, on appeal, assigns error in this ruling.
At no time during the trial did counsel for the defendant claim that the abovе ruling resulted in a denial of any constitutional right of the defendant. See

v.
Moving Pictures Operators,
Neither the grounds on which the objection was based nor the grounds on which the question was claimed were stated by counsel as required by Practice Book § 226. If a defеndant in such a situation wishes to except to a ruling excluding evidence which was оbjected to only generally, he must avail him

self of the provisions of the rule and state his claim of admissibility.
Acampora
v.
Ledewitz,
“All this is but an obvious applicаtion of the fundamental rule of appellate procedure in the review of evidential rulings, whether resulting in the admission or exclusion of evidence, that an аppellant has the burden of establishing that there has been an erroneous ruling which was probably harmful to him.”

v.
Connecticut State Board of Education,
In addition, the record shows that no exception was taken to this ruling on evidence so as to make it

a ground of appeal. Practice Book §226; seе also § 648. This court will not review rulings on evidence where no exception was taken as required by the rule.
Ferreira
v.
Storms,
During the course of a trial, objections to rulings on evidence are numerous, and often indiscriminately made and summarily disposed of. An excеption, being a protest against a ruling of the court, makes clear that the party unfavorably affected by a ruling is not satisfied and does not acquiesce therein. Thus, the trial court is notified of those rulings which are relied on as grounds for appeal and is given an opportunity for second thought and possible correсtion at that time or at a later stage in the trial. See
Zalewski
v.
Waterbury Mfg. Co.,
There is no error.
In this opinion the other judges concurred.
