TO 



SIR JOHN EICHAEDSON, M.D., F.E.S., 



INSPECTOR OF HOSPITALS AND FLEETS, R.N.. 

 ETC., ETC. 



My dear Sir John Richardson, 



Since the time (now thirteen years ago) when, a subaltern under your orders, I 

 learned to admire your character and to respect your high scientific attainments, we have met 

 but rarely ; and the arduous and perilsome service into which your sense of duty has led you 

 in the interval, may well have obliterated from your mind all recollection of the fact that 

 I owe to you those opportunities for scientific observation which I have enjoyed and have 

 endeavoured to use. , 



If I remind you of such a matter, it is only that I may seem less bold in venturing to 

 dedicate to one so justly honoured as a man and so esteemed as a naturalist, these late first- 

 fruits of a beginner in zoology. 



I am, 



My dear Sib John Richardson, 



Yours very faithfully, 



THOMAS HENRY HUXLEY. 



The Government School or Mines, Jekmtn Street ; 

 Augusl IWi, 1S59.
