On the macroscopic determination of igneous rocks
Transactions of the Edinburgh Geological Society, 1888 The object of this paper is to contribute some small item to the very scanty knowledge we at present possess as to the best means of macroscopically determining rock species. In this communication I will confine myself to the consideration of certain simple and easy methods for the identification of Igneous Rocks which I have used with fair success for

V.—The Constitution of the Igneous Rocks [PDF]
Geological Magazine, 1909 In a paper read at the 1903 meeting of the British Association and afterwards published in this Magazine, the method of calculating the chemical constitution of the igneous rocks by the collation of analyses was criticized, and the results were compared with those based on actual field-work in an area where such rocks were very abundant. Mr. F.

XXI. The Igneous Rocks of Bute [PDF]
Transactions of the Geological Society of Glasgow, 1916 The geological claims of Bute seem always to have been overshadowed by the near presence of Arran, with its superior size and variety of formations.

Bryce, in his “
