Where the response precedes the appearance of albuminuria, it fades when the albumin becomes copious, and reappears again as it diminishes or after it disappears. The most useful application of the test, according to Mahomed, is in the prealbuminuric stage of scarlatina, where it will give us information of a state of affairs in the kidney previous to actual inflammation of the organ, when a brisk purge or copious sweat may avert more serious mischief. In cases of albuminuria produced by intense fever and due to venous congestion, as in enteric fever, pneumonia, and sometimes in the febrile stage of scarlatina, when the fever is intense and the albuminuria only slight, no reaction showing the transudation of the haemoglobin can be obtained. 2. The presence of hsemoglobinuria as distinguished from hacmaturia is determined by the absence of blood discs and the presence of a smaller quantity of albumin, derived from the decomposition of the hemoglobin. When a solution of haemoglobin is heated in a test-tube it breaks up into a coagulated albuminous substance, haematin and methaemoglobin. The former is precipitated not in flakes which quickly coalesce and form a large, white, bulky precipitate, as does coagulated serum-albumin, but forms a small, brownish, coherent coagulum which floats upon the surface. The color may be removed from the washed coagulum by boiling with alcohol containing sulphuric acid, the fluid becoming tinted reddish to reddish brown, and giving the spectrum of haematuria. Again, the color of such urine, although dark red in bulk, is yellowish and more transparent in thin layers than urine containing blood-corpuscles. It is of lower specific gravity than such blood, and...
