2 General Pathology. 



1. 3. Skeleton of a Mole {Talpa vulgaris). — The bones of the 

 fore limb are developed greatly in excess of those of the hind 

 limb. This difference corresponds to the greater use made of 

 the fore limbs in burrowing. The development of muscle 

 corresponds to that of the bones. G. C. 3137.

1. 4. Hypertrophy of Bladder Wall associated with old- 

 standing' Stricture of the Urethra. — Preparation of 

 bladder, part of penis, and urethra. The bladder and prostatic 

 portion of urethra are opened from above. The prostatic 

 abscess, and the membranous and spongy parts of the urethra, 

 are opened from below. 



The patient, who had suffered from stricture for some years, had been 

 in the habit of passing soft bougies on himself. Two days before his death 

 he had sent for a surgeon, "who found him sinking" (probably from 

 extravasation of urine). 



Above the stricture, which was very narrow and plugged by 

 a calculus, the urethral mucous membrane is dilated, ulcerated, 

 and covered with "calculous" (phosphatic) deposit. The 

 prostate has become an abscess cavity communicating with 

 the urethra. A thick white rod shows where the urine had 

 escaped into the cellular tissue of the penis and scrotum. 

 Smaller white rods indicate the ureters. B. C. xiv. 1. M. 41. 



1. 5. Hypertrophy of Fibula from Strain. — Plaster cast of a 



remarkable specimen of ununited fracture of the tibia which 

 is in the Barclay Collection. 



There has been an ununited fracture of the tibia, with a 

 false joint. The fibula is much bent, and is at the same time 

 greatly thickened, especially at the concavity, and at the 

 convexity of the curve. These changes have evidently been 

 the result of an increased strain on the bone, owing to the 

 ununited fracture of the tibia. G. C. 3080.
