MR. FRIENDS REPLY TO MR. HARRISON. 
tcere found to be crammed full ^ hard, and dry.^’ To the second 
and third he gave the same quantity, and afterwards, as he tells 
us, increased the purgative treatment; and in these cases, after 
death, the stomachs were still found ** full, but of a softer con¬ 
sistence'’ than the contents of the stomachs in the first case. In 
the fourth case the purgative treatment was carried to a still 
greater extent; and though debility and its consequences were 
produced, “ violent purgation took place,” and the stomachs were 
effectually relieved. The symptoms were properly watched ; that 
tact which distinguishes the scientific veterinarian was displayed; 
tone was given to the stomachs, and the animal recovered. 
Now, gentlemen, does a calm review of these facts, sucli as I 
have stated them (in all points fairly deduced from, and in most 
using even Mr. H.’s own words), prove an excess or a deficiency 
in purgative treatment ? Let us retrospect them. In the first 
case, where only ifeij of magnes. sulpli. was given, during the 
progress of the disease, no perceptible effect was produced on the 
stomachs; in the second and third, where more was given, a very 
perceptible though not a sufficient effect was produced; and in 
the fourth case, where a still greater quantity was given, and 
more powerful (for the ol. ricini was added to the magnes. 
SLilph.), and in a shorter space of time too, the required effect was 
produced, and the animal was saved. 
It is rather unfortunate for Mr. H.’s theory, that in four 
cases brought forward and designed by himself to illustrate the 
evil effects of strong purgatives, the only case that recovered 
was that one in which the purgative treatment was carried to 
the greatest extent. It is saying nothing in his favour, that 
tonics, 8cc. were employed in this case, because, before this was 
done, the grand object was accomplished ; the stomachs were 
relieved by the purgative treatment alone, a circumstance which 
he has himself proved never was accomplished in the first three 
cases. 
You will find that I perfectly agree with Mr. H. in the effect 
and necessity of strong stimulants and tonics, in conjunction 
with purgatives, in all cases where the rumen and reticulum are 
incapable of acting; and this I do from a conviction, that what 
would produce injury in some parts, by increasing the circulation, 
and exciting and irritating the nervous system, is here desirable, 
for this is the very effect we would wish to produce. 
I cannot omit so favourable an opportunity of adverting to the 
effect of the magnes. sulph. when given to cattle. In p. 295 of 
TiiiiV ETERiNARiAN for Juoe, you will find I made some remarks 
upon its use, which are admirably borne out by these cases.
