I believe that I could produce this deposit at pleasure in male sheep by feeding them on saccharine roots and oil-cake, so that here we have positive evidence that one form of concretion in a lower animal depends upon the nature of the food. The sheep is, moreover, subject to small compact calculi in the bladder and kidneys, but these are composed generally of car- bonate of lime, and are comparatively rare. The largest and best collection I have met with of urinary calculi in the lower animals is in the Hunterian Museum. At the Veterinary College Museum, there are several from the horse and ox, but there is no proper account of these in the catalogue. In other museums, as St. Bartholomew’s, Fort Pit, Irish College of Surgeons, and the Boston Museum, specimens are met with. The collection in the Hunterian Museum is thus classified, aud the analysis of the calculi will enable us to form an interesting comparison of the com- position of human urinary calculi and those of the lower animals: Uric acid.—Ostrich, and bladder of iguana. Urate of ammonia.—Kidney of sheep, rectum of fowl, eagle, and boa constrictor. Oxalate of lime.—Two, ureter of bog. Uric oxide (xanthic oxide).—Guano. Phosphate of lime.—Ureter of sturgeon, beluga, mosco, and rabbit. Phosphate of magnesia and ammonia.—3 dog, 1 hog, and 1 whale. Mixed phosphates (fusible calculus).—3 dog, 1 monkey (probably from the kidney), 3 horse, 6 ox, and 2 hog. Carbonate of lime, or carbonate of lime and magnesia.—Horse 19, ass 1, hog 5, rhinoceros 1, ox 13, and tortoise 1. It will be seen by the above analysis that the carbonate of lime calculus, so rare in man, is the most frequent among the lower animals, and. that the uric acid calculus, so common in the human subject, is comparatively infrequent in the lower mammals. Urinary calculi in wild animals are probably very rare. Sir D. Gibb (‘ Trans.,’ vol. vii, p. 401) showed a ui’inary calculus weighing three grains, and composed of oxalate and carbonate of lime, from the bladder of a field mouse (A. arvalis). This animal was found by my brother, Dr. Henry Crisp, on the wall of a salt-water river in Suffolk. But the most remarkable example is described in the ‘ Boston Museum Catalogue.’ C^culi weighing S6 lbs. were taken from the urinary bladder of an old “ bull ” sperm whale ; one of these
