HARDENING AND EXPANDING THE HOOF.

For the infusion — the rule I have adopted for defining the 
strength is, to use a sufficient quantity to make the infusion of the 
colour of rather strong tea, about a moderate sized handful of the 
fresh plant to a pint of boiling water : of course, the acridness of 
the plant will be affected by the character of the soil in which 
it grows, as also by the season, whether it be a wet or a dry 
one. The quantity that will be required of the plant in a dried 
form will be less both for the ointment and infusion.. 
The class of diseases in which I have found it most useful is 
that of papular eruptions which causes the hair to fall off in patches 
more or less in extent, and which depends upon some derangement 
of the alimentary organs ; and though the correcting of this de- 
rangement will often entirely remove them without any topical 
application, yet many cases occur of an obstinate character which 
require very active topical remedies : it is in these cases that I have 
found the greatest benefit, and I have observed that the hair has 
been more quickly restored by the use of infusum anthemidis cot. 
than after the employment of any other remedy. I do not believe 
it would be of much service in mange or its kindred diseases. If 
it be desired to preserve the plant in a dried form, it should be col- 
lected just before it is in full bloom, when all the properties of the 
plant are fully developed. 
LETTER OF EXPLANATION FROM MR. MOGFORD, 
ON THE SUBJECTS OF “ HARDENING” AND 
“ EXPANDING” THE HOOF*. 
Gentlemen, — I FEEL truly gratified by the interest the remarks 
I addressed to you on the subject of foot-hardening, and my mode 
of expansion, have excited in your minds and those of others with 
whose communications I have since been favoured. I am confident 
that the principle I plead for is correct, having tested it repeatedly, 
and with uniform success. Nevertheless, I am aware that other 
influence than that I can exert in this isolated spot is necessary to 
place it before the profession in a manner to command the atten- 
* The remarks contained in this letter have been kindly sent us at our 
request by Mr. Mogford, in elucidation of his paper contained in our number 
for December, 1845. — Edit.
