OSTEOPOROSIS.

away, the cow was unable to rise. I was called after the cow 
had been down two days; cow would not eat, continually 
moaned, and strained as in act of defecation; genital parts 
swollen. On opening the vagina, there were patches larger 
than one’s hand where the mucous membrane was nearly an 
inch thick, and loosening, leaving a raw surface looking like 
a diphtheritic membrane. Injected a warm solution of per¬ 
manganate of potass. Gave dig. cinchonas, sulphuric acid 
mixture. This animal suffered much. 
I could cite several cases where force had been used, the 
animal never rising after, the hind parts becoming completely 
paralyzed. Also numerous cases of eversion of uterus from 
this cause.

In the presentation of this subject, I bring before the 
gentlemen here assembled in this Society, in a manner not at 
all satisfactory, and I fear, as viewed by you at the conclusion, 
a lame discussion on a disease not very prevalent in this 
country to any extent in an aggravated form—and yet which 
I believe is prevalent to some extent in certain localities in a 
mild form, and when existing in a degree sufficient to warrant 
diagnosis, the baneful effects of the disease have made such in¬ 
roads upon the animal economy as to baffle the skill and 
energy of the veterinarian to the extent that osteo-porosis is 
catalogued as one of the incurable diseases affecting the lower 
animals. However, I cannot believe it is a disease whose 
only sequel should be ultimate dissolution. The literature 
bearing on this disease is not abundant. In i860 Prof. Var- 
nell wrote an interesting article on osteo-porosis, and it is 
claimed that Varnell was the first to describe the disease. 
Later his article appeared in the Veterinarian of that year. 
About 1870 Sir James Baggett relates before the Pathological 
Society, London, his experience with a disease termed by
