“ Often under this treatment the disease will appear to be cut short. 
With the action of the purgative, or even before it has acted, all the symp- 
toms will disappear, and nothing remains which seems to say any further 
treatment is required. I never rest here, for experience has taught me that 
these appearances are deceptive, and the disorder has a disposition to return. 
Consequently strict injunctions are given as to diet, and a course of tonics 
is adopted : 
Disulphate of quinine .... One to four scruples. 
Sulphate of iron One to four scruples. 
Extract of gentian Two to eight drachms. 
Powdered quassia A sufficiency. 
“ Make into twenty pills ; and give three daily. 
“ At the same time I give the liquor arsenicalis, which I prepare not 
exactly as is directed to be made by the London pharmacopoeia, but after 
the following method : 
“ Take any quantity- of arsenious acid, and adding to it so much distilled 
water as will constitute one ounce of the fluid to every four grains of the 
substance, put the two into a glass vessel. To these put a quantity of car- 
bonate of potash equal to that of the acid, and let the whole boil until the 
liquid is perfectly clear. The strength is the same as the preparation used 
in human practice; the only difference is, the colouring and flavouring 
ingredients are omitted, because they render the medicine distasteful to the 
dog. The dose for the dog is from one drop to three drops ; it may be 
carried higher, but should not be used in greater strength, when a tonic or 
febrifuge effect only is desired. 
“ Of the liquor arsenicalis I take ten or twenty drops, and adding one 
ounce of distilled water, mingled with a little simple syrup, I order a tea- 
spoonful to be given thrice daily with the pills, or in a little milk, or in any 
fluid the creature is fond of. The taste being pleasant, the dog does not 
object to this physic, and it is of all importance that it should be annoyed at 
this time as little as may be possible.

“ Most generally, however, the dogs brought to us with the distemper 
have the disease fairly established before we see them. Then I never purge 
or vomit : the time when such agents could be remedial has passed, and if 
now used, though they will seem to do some immediate good, the after 
consequences are always to be regretted. The action of the purgative has 
scarcely subsided before the distemper assumes a more virulent form, and 
the probability of the termination is rendered more dark. During the dis- 
temper I pay little attention to the bowels ; and, however, great may be the 
costiveness, I never venture to resort even to a laxative, though, should I 
discover the rectum to be impacted with hard fmces, an enema may be em- 
ployed. That which I use on these occasions is composed of gruel, to which 
some sulphuric ether and laudanum have been added. 
“The cough, however distressing it may be, I take no notice of. I do 
nothing for its relief, but persevere in the tonic treatment, and become more 
strict in my directions concerning diet. The cough is only one of the symp- 
toms attendant on the disorder, and the measures likely to mitigate its 
severity will aggravate the disease; while, by attacking the disorder, we 
destroy the cause, and with that the effect also disappears. 
“ Tlie eyes I treat, or rather refuse to treat, upon the same principle. 
Whatever may be the appearance they present — even though the animal 
should be actually blind, the eye of a dull thick white colour on its entire
