94 ON THE NON-EXPANSION OF THE HORSE’S FOOT. 
I would ask any person who practises the unilateral method of 
shoeing, if he ever observed a fissure to exist in the exfoliating 
part of the sole, extending from the point of the frog towards 
the toe. This I very frequently observe in a foot about a month 
shod, and attribute it solely to the expansibility of the foot; 
therefore I differ widely in opinion from those gentlemen who 
deny its expansion ; yet, let it ever be kept in view, that if I differ 
in opinion with any one of the Association, I do not wish to 
make one rude or unpleasant allusion; but my sole aim and wish 
is, that the discussions of the Association may be continued 
with that amicability which is calculated to give valuable infor¬ 
mation to every practitioner, student, and lover of the science. 
ON THE NON-EXPANSION OF THE HORSE’S FOOT. 
Hj/ Mr. Morgan, of Ross, late of the Borough. 
Sir,— In reading your last Number for January, I felt much 
interested in the report of the Association, and was not a little 
surprised at Mr. Turner’s observations in the second debate, 
from the perusal of which any one would conclude nothing had 
been published either to prove or disprove the expansion or non¬ 
expansion of the horse’s foot. If he will refer to the Lancet of the 
28th of February, the 14th of March, and the 9th of May 1829, 
he will find a detail of some experiments instituted by me for 
that purpose. I have sent a copy of these letters, bound, for the 
library of the Association, through our worthy Secretary. Should 
you deem them worth reprinting in The Veterinarian, they 
are very much at your service; and, before I quit this subject, 
allow me to express my regret, that they were not originally 
sent there, that being their natural and proper sphere. Leather 
soles I have extensively used, and can bear testimony to their great 
value ; but I consider them as almost secondary to that of the felt 
sole, which they are the means of keeping on the feet, when 
both are nailed on together, after the felt has been smeared with 
tar, on the side which is to come in contact with the foot. This 
felt is a coarse manufacture, used for shipping, and sold in 
sheets, by Mr. Taylor, of Bow, who has a patent for it: we 
used to get it through Messrs. Borrodaile, of Barge Yard, Buck- 
lersbury. 
Cut a piece the size of the foot, to correspond with the leather 
sole, then a less one of the form annexed ; sew the two pieces
