pathological product of glanders. The diseased parts of the or¬ 
gans were sent to Prof. Piana, who confirmed the diagnosis of 
glanders. Consequently 9 suspicious cases from the same stable 
were condemned. The author decided to try the mallein test 
on these cases, and the results of his experiments are as follows :

As the result of this, the author declared horses No. VI, VII 
and VIII to be affected with glanders, No. Ill and V as very 
suspicious, No. I, IV and IX as suspicious, and the horse No. 
II not suspicious. All the horses were destroyed at the slaugh¬ 
ter-house of Mantua, and it was found that the horse No. VII 
had glandular nodules in the lung (lnng glanders), while none 
of the other horses showed the slightest sign of the disease. 
This is another instance where it is proved that we cannot rely 
upon mallein as a certainty in the diagnosis of glanders.—

Thrombosis of the Humeral Artery \Wollman ~\.—A 
nine-year-old horse showing no peculiarities while standing or 
walking, when trotted for about 15 minutes showed a lameness 
on the off fore leg, which gradually became so bad that the an¬ 
imal was unable to lift the leg, and dragged it with the toe on 
the ground ; the lameness, indeed, was so pronounced that the 
horse threatened at any time to break down. The entire body 
was covered with perspiration, with the exception of the right 
shoulder down to the forearm, which was dry. The respiration 
was very much accelerated. The extensors of the forearm 
showed a peculiar trembling motion. The pulsation of the 
plantar artery was very weak. After ten minutes rest all these 
symptoms would disappear, leaving only a slight weakness. As 
this condition always came on in the same manner a diagnosis 
of “ thrombosis of the humeral artery ” was made. The owner 
requesting treatment, slight exercise was given twice a day to the
