Abstract
November 2, 1847.—An improved method of making gelatine medicinal capsules, which was widely adopted later, was probably the invention of a French chemist but was patented in England in the name of James Murdock, the patent agent, on Nov. 2, 1847. The capsule was made in two similar parts, formed by dipping the end of an iron rod of the required dimensions and shape into a solution of gelatine, one part fitting into the other and the two being hermetically sealed together by moistening the overlapping edges. The inventor preferred to use a vegetable gelatine produced from a species of marine moss.
