Abstract

20,118. Ransford, R. B., [Nederlandsche Gutta-Percha Maatschappij]. Sept. 5. Gutta-percha, extracting from shrubs &c.- Leaves and twigs containing gutta-percha are very finely ground, care being taken not to raise the temperature during the operation. The mass is placed in water at 70-7.5‹ C., but not higher, and stirred. This causes the particles of gum to coalesce and float to the surface.
