(1768-1848), who had experimental surgery as a hobby, wrote In 1823 I made the following experiment on a dog. I divided the vas deferens on one side and the spermatic artery and vein on the other. In 1829 I killed him, and found the vas deferens below the division excessively enlarged and full of semen (sic), and entirely stopped, with some separation of its extremities; but it was open from the place of division to the urethra. The testis upon that side on which the artery and vein were divided gangrened and sloughed away... The testis on the side on which the duct was divided became somewhat larger than natural. l kept the dog for six years; during that time he was twice seen in coitu, but the female did not produce. This was in 1827. From The Illustrated Book of Sexual Records. © 1974, 1982, 1997-2001 G.L.
