mal. I ordered the hair to be shaven from the tumour, and that, 
every day, three drachms of the strongest mercurial ointment 
should be rubbed into it, the part being afterwards covered with 
a warm lamb-skin. The resolution of the tumour was effected in 
twelve or fifteen days. I should have preferred the ointment of 
the hydriodate of potash, but it was sold very dear at our village, 
and I had to do with a poor client.” 
We should like to have — we entreat — the opinion of some of our 
correspondents who have a large cattle practice on these cases. 
We have known the iodine produce similar effects in a little longer 
time. 
We must, however, do M. Gelle the justice to state, that he has 
been speaking of simple parotiditis, unmixed with any pharyngeal 
or laryngeal affection. If these appear, as they too often will, and 
if any bronchial affection is afterwards associated with these tu- 
mours, it is a very different case. We are inclined to think that 
the difference between us and M. Gelle hinges here. In France, 
pure parotiditis is not unfrequent, and wrll then undoubtedly yield 
to the treatment which he describes; but in our cattle, less worked, 
or not worked at all, and with far more flesh and fat and tendency 
to inflammatory action about them, it is a very different thing; 
and acute inflammation can scarcely arise in any part without in- 
volving other tissues or organs, and requiring prompt and powerful 
measures to effect a cure. 
What an instructive commentary on all this do the cases of 
“ Tumours in Cattle,” described by Professor Dick in The VETE- 
RINARIAN for June, afford. Enormous sarcomatous tumours sud- 
denly appear about the superior angle of the lower jaw. They are 
of a medullary sarcomatous nature — they speedily attain an im- 
mense size. If they are removed by the knife or by iodine, the 
animal does well ; but if they are suffered to remain, they under- 
mine his constitution by the continued irritation which they pro- 
duce, and the animal wastes away, and dies in the course of a few 
weeks. A common name for this disease is “clyers.” 
The remarks of Professor Dick on the predisposition in cattle to 
these diseases are so much to the point, that we transcribe them, 
although they have so lately appeared in our Journal. They satis- 
factorily elucidate Professor Gelle’s observations on the tempera- 
ment of cattle. “ There is in cattle a strong tendency to this form 
of disease, under every circumstance in which a part is inflamed, 
either from internal derangement or external injury. There is, in 
fact, a weakness of constitution in cattle, from which their diseases 
have a determined likelihood either to run rapidly into putridity, or 
to sink into a chronic form. The constitution of their blood leads 
us to this supposition ; for in cattle there is never to be found that 
separation of the constituent parts, by which what is termed the 
buffy coat is made *o appear.”
