He is waiting to hear about the requirements for the MB examination before considering the possible trip to north America.
He is waiting to hear about the requirements for the MB examination before considering the possible trip to north America.
CD will pay for the American trip if it takes place.
Asks whether FD can help him understand the eyes of cephalopods; is the structure the same as in the Vertebrata and are the parts developed from homologous layers of skin?
Has been pleased by a recent review.
Postscript: Is thinking of a cheap edition of the Origin [1872] in which he hopes to answer St George Mivart’s criticisms.
Asks FD whether he can get some references to good papers on cephalapod eyes.
Thanks for the cheque, and also for the offer to pay for him to go on a trip to north America with G. H. Darwin.
Explains about the attendance at St George’s hospital that is required for the MB examaminations, and how this would affect plans for a trip to north America.
Thanks for FD’s help. CD cannot conceive what Mivart means by "the identity between eyes of Cephalopods and Vertebrata".
Has invited Michael Foster to Down.
Asks who Fiske is. The articles [Harvard lectures?] are "so fair and in some respects so complimentary" that CD thinks he should write to him. [See 8058.]
Sends abstract, and will bring book on Saturday.
Asks FD questions about his sketch [missing] of ridges and furrows. [FD’s answers are interlined.]
Will FD try to persuade A. D. Bartlett to show a live snake to a porcupine and observe whether the porcupine rattles the quills on its tail? [See 8333.]
Sends drawings of dogs in different attitudes, drawn by his friend A. May. FD should not trouble CD unless he thinks the drawings will please him. [See Expression, pp. 54–5.]
Quickening of heart-beat in fear. A. H. Garrod does not think that this means that the heart is working harder.
A. H. Garrod on relationship of heart-beat to amount of work done by heart.
Sends an account of an attempt to take a sphygmograph tracing of a woman during fright
and some references that might apply to CD’s work on pulse rates during rage and fright.
Sends quotation from Armand Trousseau, Lectures on clinical medicine [1868–72] 5: 213, on interruption of menstruation in young girls upon changing schools, as an example of the effect of changed conditions of life.
Sutton says monkeys often vomit, but cannot say whether they do it voluntarily.
Klein says water ought to be changed daily. Asks to tell G Revalenta shop shut. Klein reports discovery about toads’ ova does not bear on pangenesis.
Has sent Vichy water, discusses prescription. Tell Arthur Parslow not to continue on colchicum for gout if doesn’t suit him. May go to Pryor’s on Sunday.
Fears [CD’s] albumen theory will not work because albumen is coagulated and filtered out in making extracts of belladonna, hyoscyamine, and colchicine [alkaloid poisons].
Has investigated whether it makes a difference if extracts [of alkaloid poisons] are made from leaves, seeds, or roots.
Sends to Pantlludw [North Wales] bottle of formic acid. FD and Amy [Darwin] can search for spawn. If found, keep in two basins and add 6 drops of acid to one and look for differences.
