DR. BENCE JONES ON A NEW SUBSTANCE 
of fibrin, very coarse. The urine was slightly alkaline from ammonia ; it gave a t 
plentiful precipitate with alcohol ; coagulated firmly with heat, very perfectly with a 
drop or two of acetic acid. Ferro-prussiate of potash gave no immediate precipi- ^ 
tate ; in less than half an hour a considerable precipitate had formed, which was ^ 
soluble in liq. potassse. 
November 8th. — I saw multitudes of phosphate of lime crystals : no cylinders : few 
octohedral crystals. The urine coagulated with heat even when rendered feebly 
alkaline by liq. potassae or liq. ammonise : if these were in excess coagulation by heat 
did not take place. 
November 9th. — The urine was loaded with urates. Not nearly so readily coagu- 
lable by heat as it had been the two previous days ; it bore today brisk and pro- 
longed boiling: specific gravity =1037'2. 
November 15th. — I saw the patient. He stated that he usually passed about 35| 
of urine daily. 
November 18th. — The urine had a specific gravity = 1039‘6 and was acid. It con- 
tained much urate of ammonia, phosphate of lime, and oxalate of lime ; and bore 
long-continued boiling without coagulating. The urine was filtered and the following 
analysis was made : — 
519’54 grains evaporated to dryness in vacuo over sulphuric acid, gave, — 
56’78 grains of solid residue =109’28 per 1000 urine. 
Ash =6'02 grains =11*58 per 1000 urine. 
This ash dissolved in water, filtered, precipitated by nitrate of silver and nitric 
acid, gave — 
Fused chloride of silver =48*84 grains=l*99 grain ch. sod. =3*83 per 1000 urine. 
Sulphate of baryta =1*47 grain =1*10 grain sulphate of potash =2*11 per 1000 urine. 
519*62 grains of urine precipitated by alcohol — 
Precipitate =37*16 grains =71’51 per 1000 urine. 
29*26 grains of this precipitate gave, — 
1*47 grain ash (=5*01 per cent.) =3*58 per 1000 urine. 
519*62 grains treated with alcohol — 
Dissolved =19*72 grains = 37’93 per 1000. 
Ash . . =4*17 grains = 8*03 per 1000. 
1024*48 grains precipitated by strong acetic acid — 
Uric acid =*99 grain =*96 per 1000 urine. 
Filtered fluid precipitated by ammonia, — 
Earthy phosphate =1*23 grain =1*20 per 1000. 
Hence,
