Water, sodium, potassium, ATP, amino acids, and sugars are not uniformly distributed in Rana pipiens oocytes. Concentration differences exist between nucleus (germinal vesicle) and ooplasm and between animal and vegetal ooplasmic regions. The mechanisms responsible for these differences were investigated using intracellular reference-phase (iRP) analysis. The iRP is an artificial "organelle" th...

Details are given concerning the construction and operation of relatively simple thermostats which permit maintaining precise temperatures down to 0 degrees C. (with water), or temperatures above that of the ordinary room, and in which the temperature may be quickly altered at short intervals to new levels.

essential is to have the patient under observation for two or three days, during which he lives his ordinary life, and partakes of his ordinary food.
