33. _Artificial Respiration._--Dr. J. WARE of Boston, relates in the New England Jour. for April last, that he was led by the experiments of the justly celebrated physiologist Mr. BRODIE, to employ artificial respiration in the case of an infant 9 weeks old, whose system was prostrated from an over dose of laudanum. "The action of the heart was reduced to an occasional throb; the pulse had entirely ceased, and the efforts at respiration, which for some time had consisted merely in an occasional gasp, became more and more unfrequent." The child had been afflicted for five or six weeks with hooping-cough, and had been very sick and feeble when the laudanum (about 15 drops) was administered. By means of the stem of a tobacco-pipe, artificial respiration was excited, and continued for several minutes: the action of the heart was immediately renewed, and the pulse could be again felt. At the end of an hour, during which the artificial respiration was repeated at intervals; "the respiration became natural, the pulse distinct and tolerably strong, and the heat began to return." A fit of coughing, preceded by a livid appearance of the forehead and face, arrested the breathing, "which did not return till assisted by the artificial process." The child, assisted by these measures, and by attention to the more usual means of recovery, struggled through the night, but died during a paroxysm of coughing in the morning. The conclusions of Mr. BRODIE are, that narcotics destroy life through the organs of respiration, and hence, if respiration can be artificially carried on until the effects of the narcotic subside, life may be preserved. Dr. WARE'S case would seem to confirm this idea; for it is _probable_ his patient would have recovered from the effects of the narcotic, if the paroxysms of coughing had not interfered. 34. _Secale Cornutum._--Mr. CHARLES WALLER has lately published (London Medical and Physical Journal, April 1826,) several cases illustrative of the action and efficacy of secale cornutum. We have not room for any of the cases, and content ourselves with transcribing Mr. W.'s inferences. These are: "That the secale cornutum is a remedy which is capable of increasing the force of the uterine contractions in a most remarkable manner, under certain circumstances; but that the effect is doubtful, unless there be some degree of action present. In other words, that, although it will increase the contractions when already present, it will not always renew them when they are suspended. "That the effect is more certain if the infusion be of greater strength than is usually recommended; two drachms of the secale to six ounces of water being barely sufficient for the purpose. "That it appears to be a stimulus peculiarly fitted for irritable, and what are generally termed _nervous_ habits. "That the fears entertained by some practitioners of its proving detrimental to the child, are groundless.
