he was suffering from rheumatism of the throat muscles. At no 

 time during his illness did the patient simulate in any manner the 

 actions of a dog or other lower animal, although he frequently 

 referred to the dog-bite as being the cause of his present condition. 



The temperature showed a gradual rise until the second day 

 of the spasmodic stage when it reached 102 degrees F.; after which 

 it ranged between 101.8 degrees F. and 100 degrees F. The respira- 

 tions, when at all regular, varied from 28 to 40, and simulated at 

 times Chejne-Stokes' respiration, especially after a series of laryn- 

 geal spasms. After unconsciousness, ether dropped on the larynx 

 and upper portion of the chest brought about a prompt respiratory 

 reaction. 



I had an opportunity to make but one examination of the urine, 

 the specimen being collected during the second 24 hours, after the 

 onset of active symptoms. It was high-colored, decidedly acid, and 

 showed a specific gravity of 1,040; there was no albumin nor sugar 

 present. No microscopic examination was made. 



Pi'oplujlaxis . — All linens, towels, etc., used around the patient, 

 especially those contaminated with saliva or vomit, were at once 

 thrown into scalding water and later boiled. After death, all 

 needles, thermometers, spoons, etc., were either destroyed or steril- 

 ized, and the floors, bedding and furniture thoroughly wiped off with 

 a strong solution of carbolic acid. 



Autopsy . — The autopsy was made 10 hours after death by Drs. 

 McCarthy and Ravenel, with the following results: 



The lividity of the dorsal surface of the body was very marked, and rigor 

 mortis of the upper and lower extremities very well developed. 



The skull was thin. The brain and membranes were nortnal, both over the 

 convexity and base. 



The spinal cord and its membranes were of normal appearance, as were the 

 pancreas, adrenal glands and spleen. 



The lungs showed some adhesions in the right pleural sac, a rather marked 

 emphysema along the anterior border of the right lung, and an area of healed 

 tuberculosis at the right apex. 



The liver showed a slight passive congestion, otherwise normal. 



The heart was normal with the exception of a patch of old pericarditis on 

 the anterior surface. 



The kidneys appeared to be normal. The inner surface of the larynx was 

 covered with dirty mucus and there was considerable frothy mucus in the 

 trachea. 



Microscopic Examination. — The microscopic examination of the central ner- 

 vous system shows typical tubercles of Babes in the medulla. The round-cell 

 infiltration around the blood vessels was very distinct. 



Sections of the cerebral cortex and base of the brain show no evidence of 

 inflammatory change. 



Sections of the gasserian ganglion and also of the intervertebral ganglions 

 show a round-cell infiltration in the stroma, a diffuse chromatolysis of the 

 ganglion cells, and a vacuolization of some of these cells, with a proliferation of
