Summary

Cancelled: part of 1757. Has examined a specimen of [of what he had previously described as the ovaria of Lepadidae, see Living Cirripedia 1: 57-8]. Could not find cells resembling ovigerms. When THH has seen the organ in different states, and can say positively that in none could ovigerms be in formation, CD will 'give up the ghost handsomely and entirely'.

Summary

Sends specimens of sessile cirripedes for corroboration of their cementing apparatus.

Absence of anus in Brachiopoda and Alcippe cirripedes.

Summary

Thanks THH for corroborating his observations. Discusses metamorphosis of ovaria to cement organs. Ovaries, germinal vesicles, and anatomy of cirripedes. Difficulties of classification, and observation.

THH’s article on Mollusca [Charles Knight, ed., English cyclopædia: a new dictionary of universal knowledge (1854–70) 3: 855–74].

Summary

Thinks J. O. Westwood deserves Royal Society’s Gold Medal. Asks THH’s opinion of his nomination. Lyell deserves Copley Medal, but, since he has Royal Medal, it may be objectionable to propose him.

Summary

Thomas Bell thinks John Lindley superior for Royal Society Medal. CD agrees, but demurs at Medal going to same branch of science two years in succession.

Perplexed about Albany Hancock’s qualifications compared with J. O. Westwood’s.

Death of H. De la Beche.

Summary

Asks whether THH will attend Council of Royal Society and speak for him on Joachim Barrande and J. D. Dana.

Summary

Responds to THH’s questioning of his observations on cirripede anatomy with extensive discussion of what he observed. Admits his elementary knowledge of microscopical structures but seriously doubts he has erred. Cement glands, ovarian tubes, etc.

Summary

Approves drawing. No one who cannot draw should attempt to be a naturalist. Suggests corrections to [Lepas?] drawing. Comments on position of ganglia, cement glands, and stomach.
