OSTEOPOROSIS.

complication, I obtain satisfactory results from the adminis¬ 
tration of either salol and phenacetine or salicylate of soda 
and acetanilid. When the rheumatic symptoms are relieved, 
I direct my attention to the deranged functions of nutrition 
and assimilation. The only medical agent I use for this pur¬ 
pose is the precipitated phosphate of lime. It is continued 
for as long a time as circumstances seem to necessitate. As 
to food, 1 always prefer a mixed diet; corn, oats and bran 
fed as a mixture will better assume essential nutriment than 
either fed separately. It is scarcely necessary to remark that 
all food should be of the best quality. 
Turning affected animals on good pasture in proper sea¬ 
son is of undoubted benefit, but they should also have daily 
allowances of grain. 
7th. 1 have not kept a record of all my cases, but I am 
sure that over 75 per cent of those treated have made good 
recoveries. Of those in which the disease is recognized in 
an early stage, which is always possible in enzootics, all make 
good recoveries when you can have the supervision of the 
animal until recovery is assured. In such cases, even the 
bones of the head, which have become perceptibly enlarged, 
regain to a greater or less extent, their normal condition. Of 
course 1 occasionally see a case beyond hope, but, as a rule, 
real bad cases can be very much improved, and often become 
serviceable work-horses when the unsightly enlarged facial 
bones unfit them for pleasure purposes. 
The length of time required for even a partial restoration 
is the great drawback when expense is considered. This 
feature prevents many owners from putting their affected 
animals under treatment, when informed of the nature of the 
disease, especially when the affected animals are of little 
value. 
Remarks. —I cannot agree with the eminent authorities 
who class osteoporosis as a non-inflammatory disease of the 
bone. The ordinary symptoms of inflammation are heat, 
pain, redness and swelling, and they are also the ordinary 
symptoms of osteoporosis. 
The quantity and quality of the food and water have
