Plates CLXXXIX., CXC., CXCI., and CXCII. 
The Council of our Society having, as our excellent President has 
explained, determined to found an Annual Quekett Lecture, have 
done me the distinguished honour of requesting me to deliver the 
first of the series. With this gratifying invitation I cheerfully 
complied ; and the more gladly because though of course I did not 
know Mr. Quekett as well as some of you who are now present, 
still, being so much his junior, I was perhaps, on that very account, 
in one respect, better able to appreciate the kindliness of his nature, 
and his readiness to assist those who were but beginners in the 
science of which he was a master. I am glad, therefore, to have 
this opportunity of expressing my warm acknowledgment of his 
kindness towards me personally. In commencing the first Quekett 
lecture, it has been thought not inappropriate that I should give a 
slight account of the distinguished biologist in whose honour these 
lectures have been founded— a biologist, moreover, specially dis- 
tinguished in those branches of natural history with which our 
Society is peculiarly concerned.
