HYDRIODATE OF POTASH AND TOBACCO ENEMATA. 239 
which they may be distinguished, and the probable termination. It 
is, moreover, necessary that you should understand (in some degree 
at least) the nature and effects of the different mineral and vegeta- 
ble poisons ; their antidotes ; the tests by which they may be dis- 
tinguished, and their effects on the animal frame. Without this 
knowledge you cannot be said to have been qualified to practise tbe 
“ veterinary art nor can you be competent to give an opinion 
on many points on veterinary jurisprudence. 
Presuming that you are, in some measure, acquainted with these 
important parts of your education, I propose to direct your atten- 
tion first to Veterinary Medical Ethics, or the duties that relate to 
yourselves, your professional brethren, your employers, and your 
patients. If “ mutual understanding” is to take place amongst us, 
you will see that the consideration of these duties constitute by no 
means the least important part of our subject, and that it will form 
not an inappropriate introduction to the second division of our sub- 
ject, Veterinary Jurisprudence. We may then conclude with some 
practical considerations for the mutual benefit and advantage of us 
all. 
Having thus laid before you the plan that I propose to adopt, I 
shall, in the next number of this Journal, commence the subject of 
Veterinary Medical Ethics. And here I trust that I may be 
allowed to say one word as a caution, — Guard against adopting 
any party prejudices, or being swayed by any preconceived notions 
on these important subjects. Let it be your especial aim to ascer- 
tain the correctness of all that you hear or see, and then “hold fast 
that which is good.” 
ON THE USE OF THE HYDRIODATE OF POTASH, 
AND ON TOBACCO ENEMATA. 
By S. V. Gregory, Esq. V. S. Sherborne. 
In The Veterinarian for this month, I see that Mr. Wardle 
advocates the use of the hydriodate of potash in bony depositions. 
Having used it extensively for several years past, both as an ap- 
plicant externally and a medicament internally, the few following 
cases may not be unworthy of notice. 
This brings me, in the first place, to make a remark on hereditary 
disease. J. Doddington, Esq. of Horsington, for some years past 
had a stallion called Hercules, a well-bred horse, of amazing 
power and strength ; but his hocks were spavined and curbed, and 
otherwise ill-formed, and he was of a very vicious temper. He was
