    the quality of the urine evolved in phthisis, hut as an American observer* has made the unaccountable obser- vation, that in phthisis, as a general thing, its specific gravity does not exceed 1010, we think it right to cite the specific gravity in the cases of phthisis now referred to. The specific gravity was determined with great care, by means of an instrument with a large bulb, and graduated to a quarter of a degree, and at the same time the exact temperature of the urine was determined. The inquiry was made in the day and night urine separately, and as the whole returns are too voluminous, we insert in the following table a copy of the record in the first eight cases. It will be observed that there was much diversity in the returns of the specific gravity, so that on one occasion it was so low as 1007, and in several others as high as 1030. Usually that of the night urine (9 p.m. to 8 a.m.) was less than that of the day. We cannot determine the true average specific gravity in these cases without the laborious process of multi- plying each return by the number of ounces of urine of the day and night separately, and adding the totals, but it will suffice if we represent the number of occa- sions on which certain specific gravities were found. Thus, A specific gravity of 1030 and upwards was found in 4'3 per cent. 1020 „ „ 65 0 „ less than 1010 ,, 2'4 „ * Extracted from the Phil. Med. Reporter, Sept. 21, by Dublin Med.
