mout.li of the bladder. The Sub-Assistant Surgeon made his incisions in the usual way, and was then greatly surprised not to find a stone. On examination, I at once came upon the well-defined, soft lips of the bladder unopened, and the entrance to the false

passage with thin undefined margin by the side of them. The stone was easily extracted, and the case made an equally good

recovery with the other. The rule, never to cut into the bladder, unless the stone can be distinctly heard as well as felt, and I would add felt as an isolated and moveable body in the bladder, is a most important one. Professor Humphrey says that the touch is often deceptive in children in whom the projecting and slightly roughened rugae of the bladder frequently communicate, when the sound is passed quickly over them, a sensation like that given by a "

stone."

Hawkins says:?"The size is determined by first traversing the surfaco of tho stone with tho convex part of tho sound from side to side, and then carrying tho point from before backwards." Also, inserting tho finger into tho rectum will assist in forming an opinion of the length and breadth of the stono and of its amount of mobility in the bladder.

Section IV. Choice

of operation?Lithotomy or Lithotrity.?Having examined the patient and decided that the case is one that may be operated on with a justifiable chance of success, the next, question to determine is the kind of operation which should be performed, i.e., Lithotomy or Lithotrity. It is not probable that lithotrity will ever be much in vogue in India, where a native would grow impatient and run away from hospital oidy half cured and iu a worse state than before the operation. Without wishing to detract from the merits of the crushing operation, yet for the comfort of those unversed in its mysteries, I will quote from a lecture by professor Humphrey, lately

published

in the Lancet.

Preliminary Treatment.?It is seldom the custom in India to subject the patient to more than one or two days' preliminary treatment. It certainly cannot be advisable to give anodynes, as these have the effect of blocking up tho secretions, nor can it often be of use to delay the operation with the object of rendering tho urine healthy by acids or alkalies; the surest plan of giving relief to his sufferings and correcting tho diseased urine, being to rid the patient of the calculus. There are some cQnditions, howover, in which it would be very unwise to operate at once,?as when the patient is suffering from constant irritative or hectic fever depending on acute or subacute congestion of the kidneys or bladder which has recently supervened, or if the patient is very emaciated and weak, rather from bad living than from the disease. If the latter bo operated upon without preliminary feeding up, even though the patient should recover, sloughing of the cornea

is liable to supervene.
