causes. Therefore, it seems possible to-day, by “ treating ” the soil alone, 
by furnishing it with the wanted phosphates, not only to prevent | but to. 
cure “ cachexia ossifraga.”” Emigration to lands where the disease does. 
not exist is also a means to obtain rapid recovery of the sick animals. 
’ The diet must be changed. Instead of fodders reaped on those poor 
soils, cereals, leguminous, such as oats, beans, peas, all the substances, 
tich in lime salts, should be given. Oil-cakes are also to be recom- 
mended. By stopping the milking of cows so as to dry them ; and again. 
by not having them covered, the consummation of phosphate of lime will 
be diminished ; but these are measures that can be only exceptionally 
applied. 
The medicamentous therapeutics, less important than the diet, must not, 
however, be neglected. Cod-liver oil (200 or 300 grams a day for cattle) 
is indicated, but its high price is an objection. Phosphorus in cakes of 1 to. 
5 centigrams a day, dissolved in cod-liver oil, has been advocated by 
many and quite recently by Bass. Cereals, grains must be preferred to 
phosphate of lime or bone dust which are so often recommended (Springer.) 
Bitter and iron tonics (gentian, cinchona, water with rust of nails, etc.) 
stimulate the appetite and strengthen the animal. Local symptoms 
(articular swellings) should be treated by frictions of warm vinegar, cam- 
phorated alcohol, spirits of turpentine. 
' In woman, castration has given encouraging results. It deserves trial 
in our large females, in the districts where osteoclastia exists.

TUMORS. 
From the clinical point of view, it is advantageous to divide the tumors 
of bones into denzgnant and malignant, without distinction of the numerous 
groups established by pathological anatomy. Lisomas and myxomas of 
bones are almost unknown inanimals. iéromas (?) have been mentioned 
in the walls of the maxillary sinuses of horses and in the inferior maxillary 
of cattle (Zundel). Chondromas (enchondromas and perichondromas) 
‘are more interesting. Gurlt has seen them in the superior and inferior 
‘maxilliaries of horses, goats and dogs; Roll in sheep and horses. Kiener 
and Peuch have published an interesting observation of osteoid chondroma. 
Perichondromas only justify extirpation. If they do not interfere much, 
‘it is better to leave them alone ; when they produce lameness, as in chon- 
‘dtomas of the paws in dogs, they must be extirpated ; if the lesion extends 
deeply, in the thickness of the bone, amputation is indicated. Inthe case 
of Kiener and Peuch, after firing, the tumor developed on the inferior
