To George Crawford Hyndman   16 April [1852]1

Down Farnborough Kent

Ap. 16th

Dear Sir

I am very much obliged to you for your kindness in sending me the larvæ of the Balanus.2 I have seen them before but they are very fine specimens, & I daresay will hereafter come in very useful, & I will carefully preserve them.

I beg to remain | Your’s faithfully & obliged | C. Darwin G. Hyndman Esq


Dated on the basis of the paper, which has a narrow mourning border and appears to be the same as the paper used for the following letter.
The larvae in the first stage of Balanus and other Balanidae are discussed in the section on metamorphoses of cirripedes in Living Cirripedia (1854): 104–14, but Hyndman’s specimens are not specifically mentioned.


Living Cirripedia (1854): A monograph of the sub-class Cirripedia, with figures of all the species. The Balanidæ (or sessile cirripedes); the Verrucidæ, etc. By Charles Darwin. London: Ray Society. 1854.


Thanks GCH for Balanus specimens.
