Note 168 — LETTERS ON SCIENCE.

Following this letter in the same number of the Reader was one from the well-known geologist Mr. Joseph Beete Jukes, F.R.S., who, writing from “Selly Oak, Birmingham, Nov. 22,” described himself as “the originator of the discussion.” He therefore was no doubt the author of the article in the Reader alluded to above (p. 173, note). Mr. Jukes died in 1869.
