muscles, drooping head and neck, weak compressible pulse, a yel¬ 
lowish-white or blanched appearance of the eye and mouth, a 
capricious appetite, frequently total loss of it, hurried respiration, 
and in bad cases enuresis. We have here a set of symptoms all 
indicating systemic exhaustion and, I think, pointing to one line of 
treatment. I always inform our clients that the horse must be 
rested, and even but little worked, as he improves until the cold 
weather approaches (the change acts like magic), as any undue 
exertion would probably result in the horse dropping. I recommend 
a large, cool, and airy loose box during the day, and at night that 
the horse be picketed out in the open air. I have them bathed 
with cold water daily and allowed water and the grasses ad lib. 
I have found the greatest advantage from the administration, three 
times daily, of nitro-muriatic acid in conjunction with infusion of 
chorilla, one of our vegetable bitters, the compounds of iron with 
carb. of ammon. and gentian are also of great benefit; as are also 
ferri sulph. and nux vomica, twice or thrice daily. We generally also 
allow them several quarts of beer a day, mixed with gruel and 
aromatic seeds; in short, the remedies of the disease are change of 
air, general and nerve tonics. 
I am not sure that heat apoplexy should be classed with the pre¬ 
ceding diseases. There is no doubt, however, that it is a disease of 
exhaustion ; and as it is always one of the hot weather, occurring 
during the prevalence of coup de soldi and heat-exhaustion, we have 
always considered it of the same type with them. 
It is, I think, the most rapid and most certainly fatal disease 
amongst horses in India, generally only affecting iinacclimatised 
horses—horses fresh from aboard ship, generally with long coats, 
and in poor condition, and horses on board ship within the tropics. 
I have never known it to affect an Arab, a country-bred, stud-bred, 
or well-bred and acclimatised imported horse ; and those that it 
does affect are generally large-framed horses, requiring considerable 
breathing-space. I have known 50 per cent, of a ship’s cargo of 
horses lost from this disease within a few days, where the ship has 
been more or less becalmed, with the ’tween decks thermometer 
standing at 98° night and day. I have also in my memory three 
occasions on which it prevailed to some extent in the large stables in 
Calcutta. Amongst our own importations it broke out on two occa¬ 
sions during excessively hot and steamy weather ; and after losing 
several, we could do no more to arrest it than turn them loose in 
partitioned sheds, allow them plenty of water, and pray for a breeze 
and some rain. The cause of it in stables is the stationary atmo¬ 
sphere of hot; respired air. In the majority of cases death occurs 
in from a few minutes to an hour or two. I have known several 
cases linger on under treatment for a day, but I have never seen a 
well-marked case recover. The symptoms are very peculiar. There 
is an anxious expression, glassy, dilated eye, profuse perspiration 
over the neck, withers, and flank, hurried breathing, rapid pulse ; 
the horse stands with the head straight out, back arched, hind legs 
drawn well forward; he has frequent ejections of small quantities
