    a glass tube, slightly tapering, is connected by rubber tubing. I have found this superior to the pipette in point of ease of manipulation. Fill the syringe with the acid, then inserting the tip of the small glass tube inside the test-tube held inclined in the left hand, with the right fore- finger gently press on the piston. The acid will flow out very regularly and slowly, and a clear- cut, well defined zone is seen, if albumin be pre- sent. The syringe should, of course, be well packed and in good order. III.—Estimation of Quantity of Albumin. Rough Method of Estimation of Albumin:— Set the second test-tube—namely, that one in which the acidified urine has been boiled—aside, and then note the amount of albumin which has settled. If the amount is insignificant, the loss of albumin in 24 hours is under 2 grams (31 grains); if moderate, from 6 to 8 grams (93 to 124 grains); if considerable, 10 to 12 grams (155 to 186 grains); if very large, about 20 grams (310 grains). Boil daily, using test-tubes of the same size, the same amount of urine passed at about the same hour of day, adding 3 drops of acetic acid. Set the tube aside, and compare results with those of a preceding day. Rough Method of Estimation of Percentage of Albumin: Fill a test-tube two-thirds full of
