Mr. Thompson states that thickening of the tissues is gener-ally greater on the lower than on the upper surface. Again, stricturemay involve the canal to the extent of half an inch or severalinches; when the passage is often more or less deviated from itsnormal direction, and the stricture is said to be irregular or tor-tuous. It -is chiefly in these cases that the induration is so excessiveas to implicate the whole thickness of the corpus spongiosum, or 262 STRICTURE OF THE URETHRA. even a portion of the corpora cavernosa, and form hardened masseswhich are readily perceived by the finger during life. Degree of Contraction.—The plastic material of stricture exhibitsa constant tendency to contract, and become harder and firmer with Fig. 15. Fig. 16.
