Abstract

1. Samples of cisternal cerebrospinal fluid (c.s.f.) and blood plasma have been obtained nearly simultaneously from foetal sheep of different ages, the foetus having been exteriorized and maintained in a normal state with respect to its blood gases and arterial pH. The brains were removed from these foetuses and also from foetal guinea-pigs after exsanguination.2. A comprehensive study has been made of the concentrations of water, chloride, sodium, potassium, calcium and magnesium in blood plasma, c.s.f. and brain from foetal sheep and in brain from foetal guinea-pigs during development in utero. Maternal arterial blood plasma, cisternal c.s.f. and brain from the sheep and brain from the gui..
