fiSl' . ANNUAL REPORT OF THK Off. Doc. 



sii\i(i in tubn-culai- families. Di-. Flick, wlio is at the head of the 

 I'hipps Institution for the study and prevention of tuberculosis, 

 has stated that children who have been born of parents affected 

 with tuberculosis resist it better than others, until later iu life, if 

 they j^et through without contracting the disease that shows a 

 resistance; but the fact is that so many of them get the disease as 

 a result of this exposure. 



MR. SCHWARZ: Dr. Pearson is an authority on tuberculosis. 

 I am glad to hear him talk about mad dogs. He has had quite a 

 controversy with other physicians as to whether dogs are mad or 

 not and I would like him to tell how he knows they are mad. 



DR. PEARSON: One very good way to find out is to let a mad 

 dog bite another dog and see whether the dog goes mad. It is 

 astonishing to see and hear how conllicting the views are as to 

 this disease. The rabies has as much individuality, as a disease, 

 as any other disease. It is a disease that produces a nervous 

 etTect on those bitten, causing them to have a maniacal desire to 

 bite others, and the injury is imparted by the saliva, it being 

 dropped into the wound when the bite occurs. It never arises 

 from starvation, from thirst or from heat, or from any cause what- 

 ever, excepting exposure from animals afflicted with it. Strange 

 to say there are some men who deny the existence of it. Especially 

 does this occur where they never have seen it and they think a 

 thing they have never seen cannot exist but, fortunately, this 

 class of thinkers is becoming less and less and you do not hear so 

 much of this sort of foolish talk as we did a few years ago. The 

 whole head and front of this unbelief is concentrated in a certain 

 physician in Philadelphia, who has made a report from year to 

 year and has denied the existence of this disease. It happened 

 last August that a man working in a machine shop was bitten by 

 a mad dog as he run through the machine shop. One of his fellow- 

 workmen picked up a crow^-bar and killed the dog and threw it 

 into the furnace where it was burned. Nothing more was thought 

 of it and this wound was not dressed. In about three weeks the 

 man felt a tingling sensation in his left hand and in his arm and 

 had a depression in feelings and became irritable. One morning 

 when he was going to work his wife induced him to stay at home and 

 she sent for the doctor. He said he thought it was rabies, but in 

 order not to excite anyone he was told he had inflammatory rlieu 

 matism. He began to get worse and they decided this man had 

 rabies. He was unable to swallow and v/ould get nervous and was 

 thrown into convulsions and the duration of thera became longer at 

 each successive occurrence. So this physician, who holds the re- 

 mark;il)Ie \ii \v i^n rabies, was called in and he says, no, he has no
