sought for them. In human urine I have found them ; but in 
that of the horse the crystals of carbonate of lime are most 
abundant. I have by me a slide prepared from the urine of 
a patient (an officer’s charger of the 1st cavalry) that was 
suffering from Haematuria, in -which these crystals exist in 
enormous quantities, in the spheroidal and likewise in the dumb- 
bell form, like the oxalate. In each instance they are evidently 
formed, as Professor Spooner describes them, “of minute 
needles radiating from a centre.” In this case I immedi- 
ately had recourse to acids, and with the happiest results : 
Sulph. Acid., 5ij ; 
Aquse pura, %x. 
To be repeated in twelve hours. 
I had no occasion for further treatment, except secondarily, 
acting on the urinary organs by means of a purgative, after 
the cessation of the hemorrhagic discharge. I have repeated 
this treatment in two or three similar cases, and with the 
same result, and have reason to hope it will be the means of 
saving considerable trouble, for such cases as this are very 
common here. I ought to state that the slide alluded to con- 
tains also large specimens of pavement epithelium, evincing, 
I should surmise, that the disease was affecting the kidneys 
and ureters more than the bladder. 
I write this at the last moment for the mail I have some 
other cases in store for you by-and-by. Truly yours.

My dear Morton, — I send you a line relating to pro- 
fessional matters in this part of the world, for the Veterinarian , 
which I am delighted to find is now in the hands of yourself 
and colleague. 
First. As to the diseases of the horse of this colony : they 
are, so to speak, very few. The animal seems to be well 
adapted to the country, enduring much more fatigue than the 
English horse could on the same keep. I rode one the other 
day, taken directly from grass, eighty miles up the river 
Murray in a day, to visit an entire horse. The next day I 
caught a fresh horse and rode him back the eighty miles, and 
when I got home I was far more tired than my hack. 
The breed of horses is very good out here. We have a son 
of “Touchstone’s,” one of “Cotherstone’s,” and one of “Ugly 
Buck’s,” besides many Arabs from Calcutta, and which, I
