TO A. HANCOCK, ESQ. 251 



will appear in the Annals, and tlien I shall be able to study it. 

 I have no sort of pretension to claim any favour from you, but 

 if you could at any time spare me one or two specimens in the 

 shell, preserved in spirits, it would be a most material kindness. 

 T would pledge my honour not to publish anything so as to in- 

 terfere with any further researches you might choose to make on 

 the species. No one can be aware better than yourself, after 

 your excellent labours on the MoUusca, that when one is em- 

 ployed on a monograph, trifling points are found to be of interest, 

 which are known to be so only to those employed on the class, 

 and it is on this ground that I should so much like to dissect a 

 specimen of your genus. I have now dissected species of all the 

 genera of the Cirripedia, and have nearly finished the systematic 

 part of the Pedunculata, but yet from the extreme slowness of the 

 rate at which my health allows me to work, my monograph will 

 not appear for one or two years, so that I could not encroach on 

 anything" which you might choose to publish further on the sub- 

 ject. 



I trust that the great interest which I have felt in your in- 

 teresting discovery will make you forgive my taking the liberty 

 of asking you so great a favour as that contained in this letter. 



I beg to remain, with much respect. 



Yours faithfully, 



C. Daewin.

 Dear Sir, 



I am truly obliged to you for your very kind letter 

 and offer of specimens of Alcippe. You cannot imagine how 

 much I shall enjoy seeing in your paper and in actual specimens 

 a new form of Cirripede ; for I am wearied out with examining 

 scores and scores of closely allied common Cirripedes.
