Fig. 1.

Gives a view of the director used in the operation on a child under five years of age, slightly curved towards the extremity, the more readily to adapt itself to the concavity of the bladder when held in the position in [Plate II].

Fig. 2.

The knife with a scalpel blade, but longer than a common scalpel, and slightly convex on the back near the point, that it may run smoothly along the groove of the staff. When used with a staff of this form the whole of the cutting part of the operation may be easily performed with it.

Fig. 3.

The size of the calculus which was extracted in the first operation with these instruments is here delineated, in order to shew the extent of the opening in the cervix vesicæ and prostate gland, which in so young a child may be made with safety, according to the method explained in [Plate III]. The comparative size of the incision that can be made in the adult may be inferred.
