    Believes JDF's discoveries in the structure of glacier ice will explain the structure of many volcanic masses. Will JDF's views throw any light on the primary laminated rocks?

Transcription

“How singular it at first appears, that your discoveries in the structure of glacier ice should explain the structure, as I fully believe they will, of many volcanic masses. I, for one, have for years been quite confounded whenever I thought of the lamination of rocks which have flowed in a liquified state. Will your views throw any light on the primary laminated rocks? The laminæ certainly seem very generally parallel to the lines of disturbance and movement. Believe me, &c. C. DARWIN.”
To Professor FORBES.
