ficult the differential diagnosis is between tuberculosis and some 
diseases of the thoracic cavicy, which are not inicrobian. The 
following case shows one more proof of it. A cow was brought 
to the author with the history that she was bought recently, 
was in good condition, had a calf, everything normal; was 
turned out for a while, when she was noticed to be ailing. Her 
condition grew worse and at last she was brought to him for 
advice. She was then in a cachetic condition, her whole organ¬ 
ism is affected and presents indications that she is very il), 
the trouble being* located by most minute examination in the 
chest. The respiration is accelerated and painful, 45 to 55 per 
minute, it is. abdominal and dyspncecal. Aborted cough by 
spells,_discharge from both nostrils without bacillus of^Koch 
(by microscopic examination), dullness on the left side of the 
chest, back of the shoulder. The case is one of broncho-pneu¬ 
monia of both sides, more marked on the left. Of what nature ? 
Tuberculin test is applied with thermic reaction of 1.3 0 and in¬ 
creased respiration to 92. Diagnosis of tuberculosis is made. 
1 he cow dies a little later. At the post-mortem the lungs show 
alteration of broncho-pneumonia: interlobular emphysema, 
whitish muco-pus in the large bronchi, a certain number of 
strongyli in the middle size bronchi, etc. But no mark of tu¬ 
berculosis in the lungs nor anywhere else. Although the reac¬ 
tion by tuberculin had been only 1.3 0 , the case was considered 
as one of tuberculosis by taking the cachectic condition of the 
animal. Having full faith in the value of tuberculin and the 
correctness of its declaration, the author continued his investi¬ 
gation on the cadaver, and found at last, a subglossal gland 
with a caseous centre, as big as a hazel nut, deeply situated in 
the intermaxillary space. When tuberculin has spoken and 
the lesion is not found, do not Say that tuberculosis does not 
exist, but that you have not looked well for it .—(Annates de

The Automobile in Private Use. —In relation to the use 
of the automobile carriage in this city Mr. A. C. Bostwick, who 
some time ago bought a motor phaeton, says : “ My automobile 
cost me $2500 in the first place ; then for a year I had to em¬ 
ploy an engineer at $60 a month, with board and lodging ; 
added to this I used up two batteries within the year at $400 
each, not to speak of new tires and repairs.” Eight hundred 
dollars for batteries ! At $35 per month a horse could be kept 
for two years on that item alone .—New York Herald.
