GLANDERS. 
rently remaining no symptom of illness, and we were thinking of 
sending him back to the ranks, when we perceived a very slight, 
white, adhesive discharge from the right nostril, and the sub¬ 
lingual glands on that side were engorged and tender. He also, 
in despite of treatment, became worse and worse, and was de¬ 
stroyed on the 19th of September. 
• CASE ITI.—CONCUSSION ON THE FOREHEAD. 
Two mares, six and seven years old, gallopping at full speed 
in opposite directions, came against each other with so much vio¬ 
lence, that they were both knocked backwards, and lay for 
awhile on the ground without motion and without life. 
By little and little they recovered from their stupor. The first 
had a slight wound on the anterior part of the forehead, and about 
two or three inches in circumference. Both bled profusely from 
the nose, and the one that had the wound bled from both nos¬ 
trils ;—in the other the hemorrhage did not commence until a 
quarter of an hour after the accident, and then it was from the left 
nostril only. It stopped spontaneously in both of them. They 
were both placed in the infirmary, and treated as in Case I and II. 
In the evening. Colonel Lory coming to inform himself of the 
state of these horses and of my opinion of them, I told him what 
I had generally seen to happen in similar cases, and particularly 
reminded him of the other two horses whose history has just 
been given. At the same time, however, I observed that every 
horse that had received similar contusions on the anterior part of 
the head had not become glandered. 
The event justified both of my assertions; one of these mares 
became glandered, but the other never exhibited any symptom of 
that disease. 
The first of them remained for some time in a sadly dispirited 
state ; she ate very little food ; she seemed to lose flesh every day, 
yet without presenting any symptom of definite disease. She 
continued in this emaciated state, notwithstanding all the care of 
the sub-officer to whom she belonged. Having returned to the 
ranks, she discharged her usual duty for two years, and until she 
was discharged on account of chronic lameness, but without the 
slightest symptom of glanders. 
It was quite otherwise with the second mare. The morning after 
the accident; she had regained all her former gaiety and appetite, 
notwithstanding which, however, she was restricted in her diet 
during several days. She was kept in the infirmary twenty-two 
days after her fall; at the expiration of which period there 
was a white discharge from the left nostril, the sublingual glands 
on the same side were slightly enlarged and very tender, and the
