If alcohol be added to the urine in the proportion of two to one,precipitation occurs; this precipitate is insoluble. Picric acid produces a precipitate which does not dissolve upon boiling. Formalin added to the urine produces at first a very slight cloudiness,but upon standing a heavy precipitate occurs. Saturation of the urine with magnesium sulphate causes no change,but upon the addition of acetic acid a heavy precipitate is thrown down. The biuret reaction (caustic soda and copper sulphate in weak solu-tion) is positive, producing a rose-pink and violet Fig. 3. Myeloid Sarcoma, showing giant cells (x 245). Bence Jones albumose differs from proto-albumose and hetero-albumose in that it is not completely precipitated with sodium chloridein neutral solution. It resembles hetero-albumose in that it is precipi-tated on addition of acetic acid after saturation with sodium chloride ormagnesium sulphate, but differs from it in being precipitated at a lowertemperature. (Boston.) It should not be confused with the secondary albumoses so frequentlyfound in the urine of the febrile and septic diseases, the reaction of thesealbumoses being different from those of the Bence Jones substance. Secondary albumoses do not precipitate upon boiling nor on saturationwith sodium chloride, when the reaction of the urine is neutral, but if CALE: BENCE JONES ALBUMOSURIA 399 acetic acid be added to the urine, saturated with sodium chloride, pre-cipitation occurs.
