HYPERTROPHY. 469 



1839. The horse was a coach-horse, entire, seventeen hands 

 high, who became, from being light in his carcass, '^ as large 

 as a cow/^ And when he lay upon his left side, there could 

 be seen and felt a tumour of large size, arising from some- 

 thing pressing against the parietes. There was also much 

 anasarca of the belly and scrotum. The horse covered up 

 to this time. Before his death occurred he staled blood in 

 large quantities, though that might have arisen from 

 instruments improperlj^ used. The right kidney was 

 enlarged to that degree that putting my arms round it, I 

 could only clasp my hands, but could not lift it.^' The 

 natural texture was lost ; it seemed to consist of cheesy 

 matter enveloped in a strong tunic. The other kidney was 

 healthy, though rather larger than natural. The enlarged 

 kidney was supposed to weigh upwards of 1 12 lb. ! 



M. Clipy was called to attend a horse for being off his 

 feed, which up to that time had always enjoyed good health. 

 He found his gait difficult, especially of the hind quarters, 

 and that the slightest pressure upon his loins produced 

 great pain, particularly when he was made to bend down- 

 wards, which he with all his power resisted. Urinary secre- 

 tion scanty and bloody. The next day, in raking the horse, 

 the rectum was found hotter than natural, the bladder in a 

 state of semi-plenitude, and thrust, as it were, into the 

 pelvis ; the kidneys of an enormous size ; and at the least 

 touch of them the patient expressed great pain, and struggled 

 to rid himself of the man's arm by violent contractions of 

 the abdominal muscles. In spite of the most active anti- 

 phlogistic treatment, death ensued in eight days. The kid- 

 neys were found enormously enlarged, weighing each from 

 twenty-four to twenty-seven pounds, occupying all the pos- 

 terior part of the abdomen, and in some measure blocking up 

 the opening into the pelvis, their inferior surface being upon a 

 level with the pubes. Their surrounding cellular tissue was 

 very much infiltrated, and their internal substance generally 

 reddened.
