What quantity of cyanide of silver should 100 grs. of this acid yield on the addition of a solution of nitrate of silver? State the characteristics of cyanide of silver, and how you would distinguish it from chloride of silver. If a sample of diluted hydrocyanic acid yield a red precipitate on the addition of the iodo-cyanide of potassium and mercury, what inference would you draw therefrom ? State the composition of this red precipitate, and explain the chemical changes which occur during its formation under the above circumstances. 2.

UNIVERSITY COLLEGE HOSPITAL. RUPTURE OF THE BLADDER

FROM RETENTION

OF URINE.

J. D., aged 70, was admitted on May 17, under the care of Mr. Liston. He came into the hospital at ten, A.1%1., on account of a slight transverse wound of the throat, which he had made with the intention of destroying himself. He assigned as a reason for this proceeding, that he had not passed any water since the 14th, although several attempts had been made to pass the catheter by a surgeon. On examination, Mr. Taylor, the house-surgeon, found the bladder greatly distended, and reaching nearly to the navel, with extreme pain on pressure ; but the pain was restricted, or nearly so, to the hypogasnitric ether of the shops, of becoming olive- trium. On farther inquiry it appeared that coloured on the addition of protosulphate of he had had stricture for several years, but had never before experienced a complete iron, and blue with tincture of guaiacum? 4.
