of tc'ii or twenty grains. You are, of course, aware that the nar¬ 
cotic may be pushed much further in the lower animals than in man; 
their action is directed more to the cord and less to the higher 
faculties than in man, and to get good results from the morphia 
treatment of azoturia, you must push it far enough to get its toxic 
action—you must give ten or fifteen grains every hour until the 
patient rests quietly and sweats profusely. You may push it so 
far that it induces automatic convulsive movements of the limbs, 
simulating trotting or galloping, and you will do no harm by this 
course. To reassure you, I may state that the same treatment is 
frequently adopted in the uraemia of mankind with equally good 
results. I have given a drachm in twelve hours without producing 
sleep and with excellent results. Do not be afraid of it; use 
it freely and it will do you good service. 
With regard to other treatment, I advise you to get the horse 
into slings as early as possible. If he entirely loses the control of 
Ids hind limbs, it will of course be necessary to lower him, and I 
may add that a smart stroke of the whip will often make him 
stand when hanging in them.. 
The local complication, the “ kidney trouble,” attracts usually 
most attention from the laity and the ignorant horse doctor. 
Gentlemen, let me most strongly impress upon you the fact that 
it is not a kidney affection. The kidneys are doing their work— 
are working up to the very limit of their power. Do not aggra¬ 
vate them by the use of diuretics, especially of those resinous in 
character. If you must use them, and then when on the road to 
recovery, use squill and digitalis. If there is retention, shown 
by examination of the bladder, you may pass the catheter—and 
here again a word. Do not do it until your horse is comfortably 
in slings and has had a dose or two of morphia, as I have on sev¬ 
eral occasions seen the irritation caused by the passage of the 
catheter cause convulsions and the getting down of the animal 
Of course, if you find your patient recumbent with a full bladder, 
it is well, especially in the horse, to put on the hind hobbles and 
take away the water, though personally, I prefer to pass the 
catheter standing. 
A hint about catheters. You will find the thick foreign in-
