 Abbe-Zeiss refractometer was employed, a small amount of a concentrated solution of pure gutta in chloroform placed on each of the prisms and allowed to stand until the odor of chloroform had entirely disappeared. The prisms were then closed, and kept...  Annual Report of the Directory of Lands - Page 559by Philippines. Bureau of Lands - 1903Full view - About this book
