1. A simple and rapid method of preparation of highly potent extracts of C.G. is described. 2. The method consistently produces a product containing about 4000 I.U./mg. with a yield of about 30 per cent. 3. The potency of such a product is found to be about the same whether it is tested on amphibia or mammals.
