44 LIFE OF SIR JOHN LUBBOCK c. 



Jermyn Street, 

 Sept. 15th, 1858. 



My dear Lubbock — I have been greatly interested 

 in what you tell me respecting the wide occurrence of 

 the " vitelligenous " glands in Insects. I was quite 

 unaware they had been described, but I had not looked 

 into the matter, particularly as it was only a collateral 

 point in my paper. Von Siebold so far as I recollect 

 makes no mention of these glandular bodies, which is the 

 more misleading as he is particularly well up in Insect 

 anatomy. 



I am very much obliged to you for drawing my 

 attention to the fact that these bodies have been described 

 already, and I will put a note about them into my paper. 

 If you will let me put any of your new facts into it, the 

 work will be all the more valuable. 



I have been making no discoveries. On the contrary, 

 with a more than Roman virtue and stoicism, I pur- 

 posely left my microscope behind — knowing very well 

 that the work I had to do would not be done, if I took it. 



I have been very busy working at my " Oceanic 

 Hydrozoa" and the Croonian Lecture, which was not 

 written when I delivered it. Both are I am happy to 

 say nearly finished. I used to work from half past eight 

 in the morning till two, and then stroll about all the 

 rest of the day. 



I am sorry to say I shall be unable after all to come 

 to Leeds [where the annual meeting of the British 

 Association was to be held], the death of a connexion of 

 mine having upset all my arrangements. It is very 

 annoying but cannot be helped. — Ever yours very truly, 



T. H. Huxley. 



For some time young Lubbock had been 

 preparing a paper on the Daphnia, the so-called 

 Freshwater Flea, though it is really a crustacean, 

 which was eventually published in the Philo- 

 sophical Transactions of the Royal Society, and 

 led to his election as an F.R.S. in 1858. 



There are letters connected with this paper 

 from Huxley, and also from Professor Owen, 

 speaking of it in very high terms, but they are
