THE INTELLECTUAL PRINCIPLE IN THE HORSE. 
To the Editors of “ The Veterinarian 
To what extent the mind of man influences the diseases to 
which his body is subject is no less concealed from our view 
than is the connexion or modus operandi subsisting between the 
one and the other; but we know the influence to be great, and of 
such importance that, in the successful treatment of disease, the 
mind of his patient oftentimes becomes no less the concern of 
the medical practitioner than his body. To throw a popular 
illustration upon this, now that cholera is u all the rage/’ in¬ 
quire how many hundreds, nay, thousands, of persons are running 
about with camphor-bags in their breasts, and cajeput oil in their 
pockets, to guard themselves against the attack of that unsparing 
death-hunter; and then seriously put the question to the first surgeon 
you meet, What real anti-infectious property resides in this cam¬ 
phorated atmosphere ? The bearer of the amulet is himself per¬ 
suaded that there is very much virtue in it; and through the 
force and continuance of that self-persuasion, it is that he derives 
all his insusceptibility to catch the cholera. For it is, after all, a 
fact, and a medically unexplained one, that the person who has 
faith in his camphor-bag is less liable to take disease than one 
whose mind is not fortified with any such superstition. 
If there be one subject more entertaining than another—and 
let me add, Messrs. Editors, if there be one on which you and 
your various correspondents seem to have thought less than on
