The Author studied the blood volume and the specific gravity of blood in 10 infectious diarrhoea cases, prior to its onset, during the actual course of the disease and in the convalescent stage, and observed that : (1). The total blood volume is found on an average 81.9 cc prior to the onset of symptoms, 80.1 cc during the actual course of the disease when it is, although so slightly, seen decreasing, and 84.5 cc in the convalescent stage per every kilogram bodyweight. (2) The plasma volume is found, on an average, 39.5 cc prior to the onset of symptoms, 32.2 cc during the actual course of the disease when a remarkable decrease is noted before it exhibits 40.9 cc as it takes a favourable turn. Such decrease takes place in every case without a single exception. (3) The volume of the blood-corpuscles is found, on an average, 42.4 cc prior to the onset, 47.9 cc during the actual course of the disease when a distinct increase is seen, and, 43.6 cc in the convalescent stage per kilogram bodyweight. Such increase takes place in every case without fail. (4) Haematocrit is found, on an average, 51.6% prior to the onset, 59.9% during the actual course of the disease and 51.8% in the convalescent stage, denoting a constant increase during the days the diarrhoea lasts. (5). The specific gravity of the blood and blood-plasma is found, on an averge, 1.0592 and 1.0273 respectively prior to the onset of the symptom, 1.0644 and 1.0286 during the actual diarrhoeal course when an increase is noted, and, 1.0584 and 1.0270 as it takes a turn for the better. (6). The amount of the portein in the blood-plasma is found, on an average, 7.6g/dl prior to the onset of symptom, 8.1g/dl during the course of disease to remind an increase and 7.5g/dl in the convalescent stage, while the total amount of the protein in tne circulating blood-plasma is found decreasing during the course of disease, to record on an averge, 173g prior to its onset, 146g during the actual morbid days and 176 when recovering.
