Catalogue of the appendages and other parts of Cirripedes, mounted as microscopical slides

Editor’s notes: As of 22 March 2022, the transcripts has been uploaded here. There are a number of illegible words I am not able to crack. Help is welcome. The transcript will be uploaded to Darwin Online in due course where the images and the text can be seen side-by-side. References are from Darwin: A Companion, 2021.

Transcript:

Xerox copy of this catalogue was made June 1972 and is kept with the slides. R. D. Norman. Mr. C. Darwin’s Catalogue of the appendages and other parts of Cirripedes, mounted as microscopical slides.

The Collection was received on Feb. 20, 1897. Mr Darwin’s numbers have been retained on the slides, which have been arranged systematically, in accordance with the order of the species in the two volumes of the Cirripede Monograph published by the Ray Society.

Feby. 20th./55/ Sent to Mr Huxley

280 Cornuta

219 Chelonobia appear to complexity glands [illeg]

203 Elminius complex

285. B. [Tintinnabulum] shiny gland

179 origin frame

A note on the paper used in this catalogue

The full sheet torn in half is then folded to give a convenient page size. The handwriting is contemporary with the Cirripede work. There seems no reason to doubt the record of the slides was made at the time of their preparation.

pp1-18 probably earlier than the rest- in Lady Barlow’s possession are children’s drawings on the backs of cirripede notes on similar paper to this.

pp. 19-28 the paper closely resembles that used for the full version of the ‘Origin’ begun “By Lyell’s advice May 14th 1856.”

The cirripedes were “packed away, began working notes for species theory” Sept. 9th 1854.

Pedunculated Cirripedes appeared 1851

The remainder 1854.
