The authors have analyzed the various clinical features of 100 children in the Memorial Hospital, Montreal, who were suffering from acute rheumatic fever and chores. The results of their analysis are in accord with impressions which prevail in other sections of this continent and present nothing new. They call attention to the frequency with which chorea and rheumatic fever are related in the same child. Dresbach, Melvin, and Waddell, Kenneth, with Denervated Hearts.

Emesis in Cats Pharm. and Exper.
The authors studied the effect of strophanthidin introduced by various paths into eats who had been previously operated upon so as to isolate the heart from all nervous control. They conclude from their experiment that atrophanthidin will induce vomiting after thorough denervation, provided the cat has been given time to recover from the immediate effects of operation. They conclude that the action of the drug is central in its location and state that the vomiting center in the medulla is the probable location. In preparing cats for the experimental study the authors have found numerous paths of nerve control to the heart other than the vagi and the paths through the stellate ganglion. These paths, as well as the procedure for severing them, are described in detail. Danielopolu, D.: 1926, i, p. 80.

The author reviews the development of his ideas concerning the proper operattion for the relief of angina. He states that his present attitude is to recommend the removal of all paths of the cardioaortic sensory fibers without touching the important cardiac accelerator fibers which pass through the stellate ganglia. These sensory cardiac paths include the cervical sympathetic trunk, the fibers of the cervical vagus nerve and its intrathoracie branches, the vertebral nerve and communicating branches uniting the inferior cervical gangbon and the first thoracic nerve with the sixth, seventh, and eighth cervical and first dorsal nerves. He feels that unfavorable resuIts come from removal of or interference with the stellate ganglia. McCrudden, Heart

The author analyzes his findings in a small, unselected group of 100 children, ail of whom showed rheumatic heart disease with valvular injury severe enough to be in bed. Eighty of the 100 cases showed sinus arrhythmia so evident as to be easily detected. The cases with arrhythmia showed a lesser degree of enlargement, a lower percentage of activity, fewer cases with pulse rate over 100, fewer signs of decompensation, and fewer signs of more than simple myocardial damage. In other words, in the 20 cases not showing arrhythmia, these phenomena were all present in greater degree and frequency. He also notes the subsequent course of the two groups. Those children with the arrhythmia died in a short time after the original observation. While the absence of sinus arrhythmia in children does not distinguish those having heart disease from those not having it, it is evident that it indicates a bad prognosis.
