Verification of Recent Hæmatozoal Discoveries in Australia and Egypt

saie position, and the striaht probe pointed bistouiy is run alona the groo *e, to insure complete division of all bands or other obstiuctions. These being thoroughly cleared, the old difficulty of directing the point of a catheter through the divided stricture and onwards into the bladder is to be overcome. To effect this, the point of the probe-gorget is introduced into the groove in the director, and, guided by it, is passed onwards into the bladder, dilating the divided stricture, and forming a metallic floor, along which the point of the catheter cannot fail to pass securely into the bladder. The entry of the gorget into the latter viscus is signalised by an immediate gush of urine along it. The short catheter is now passed from the meatus down into the wound; is made to pass once or twice through the divided urethra, where it can be seen in the wound, to render certain the fact that no obstructing bands have been left undivided; and is then, guided by the probe-dilator, passed easily and certainly along the posterior part of the urethra into the bladder thus (Fig. 4). The gorget is now withdrawn ; the catheter fastened in the urethra, and allowed to remain for three or four days ; the elastic tube conveying the urine away to a vessel under or by the side of the bed. After three or four days, the catheter is removed, and is then passed daily, or every second or third day, according to circumstances, until the wound in the perinocum is healed; and, after the parts have become consolidated, it requires, of course, to be passed still from time to time to prevent recontraction.
