was opened and the tooth extracted. It was the ordinary size of 
a temporary molar. From the fangs to the highest part of the 
cutting surface measured one inch. The fangs, three in num¬ 
ber, seemed half absorbed, having a rounded, smooth appearance. 
•The cutting surface was very irregular, much higher on one side 
than the other, the lower part being made up of small protuber¬ 
ances covered with enamel. 
A Peculiar Pharyngeal Case. —Under this heading, 
Prof. J. Mcl. McCall relates a very peculiar case of laryngo¬ 
pharyngeal difficulty, accompanied with symptoms of purpura, 
for which tracheotomy had been performed and presented the 
singular symptoms of being unable to swallow liquid or solid ; 
whenever he took drink there was a steady stream of water or 
thin gruel flowing from the tube, and yet the horse would never 
cough during the process, and only occasionally coughed after 
the stream had ceased to flow. The case terminated, however, 
satisfactorily, as the animal was kept up by nutrient enemata 
per rectum, of beef, of milk and eggs, administered every two 
hours, with local applications of medicated poultices to the 
throat. A week of treatment brought him to a state of conval¬ 
escence.— [Ibid .)

A Contribution to the Diagnosis of Tuberculosis 
[A beau ].—By the bacteriological examination of the blood and 
various organic fluids, especially the seminal fluid, the author 
has succeeded in diagnosticating diseases, bacterial in origin, es¬ 
pecially tuberculosis. Koch and his pupils assert that his 
(Koch’s) bacillus is the exclusive characteristic of and the cause 
of tubercular lesions. Cornil and Babes deny this for the fol¬ 
lowing reasons: 
(a) Spina recognized a great variety of forms of bacteria in 
tubercular lesions. 
(b) Toussaint found immobile micrococci in the tubercular 
lesions. 
(, c ) Cornil and Babes have in their investigations found both 
in the secretions and upon section, minute nodules which stain 
similarly to Koch’s bacilli. 
(d) Klebs doubts whether Koch’s bacilli are the sole cause 
of tuberculosis and believes that certain granulations similar to
