Description

The authors write: 'Although there are many qualitative analyses of pearls, from our being unable, in their voluminous literature, to find any evidence of a quantitative analysis of their ingredients having been recorded, we undertook the examination of several varieties, of which the following is an account:— 1st. As regards oyster pearls. Of these three varieties were examined, British, Australian, and Ceylonese. The qualitative analyses showed that they all had an identical composition, and that they consisted solely of water, organic matter, and calcium carbonate.'
