1. Chapters on the Mineralogy of Scotland Chapter III. The Garnets

Abstract

In this third chapter Dr Heddle submits the results of his analyses of garnets from thirteen localities.Notwithstanding the great frequency of the occurrence of the mineral, it is generally so largely contaminated with quartz that he was unable to procure, from many localities, specimens fit for examination.Three varieties of garnet new to Scotland—one of these being altogether new—have, however, been the reward of the present investigation.
