In the New York Medical Journal, March 9, 1889, Dr. Dillon Brown gives the result of 200 cases of intubation of the larynx for diphtheritic croup, performed by himself, and in addition collates from the published statements of 165 other operators in America, Germany, France, England, Spain and Canada, an aggregate of 2,168 cases, making, with his own, a total of 2,368 cases, by 166 operators. Of the whole number 647, or 27.3 per cent., recovered. Of the 200 cases operated on by Dr. Brown 54, or 27.3 per cent., recovered. He mentions having seen 23 additional cases that recovered without operation, and 4 that died, in which intubation was urged but refused. The alleged causes of death in 144 of the fatal cases intubated by Dr. Brown were: extension of the disease to the bronchi, 63; sepsis, 24; pneumonia, 15; exhaustion, 11; nephritis and convulsions, 11; sudden heart failure,
