me to convey to you the expression of their high sense of the value 
of your labours for the advancement of the science for the cultiva- 
tion of which the Socicty has its being. For many years you have 
devoted yourself with great assiduity to the study of the Fossil 
Crustacea, founding your work upon those objects upon a thorough 
systematic acquaintance with their existing relations; and by this 
combination of zoological and paleontological knowledge, you have 
been enabled to work with great profit upon an exceedingly difficult 
branch of the science of extinct organisms. It would be a work of 
supererogation on my part (even did I feel capable of doing it) to 
enumerate the many valuable contributions to this department of 
natural history with which you have enriched the pages of our 
“ Quarterly Journal” and of other periodicals ; but I may refer espe- 
cially to your most important memoir published by the Paleonto- 
graphical Society, on those remarkable types of Paleozoic Crustacea 
which have been united to form the order Merostomata. Your cata- 
logue of British Fossil Crustacea, although one of those works which 
may appear to be mere products of laborious industry, nevertheless 
shows many evidences of critical acumen, which raises it far out of 
the ordinary level, and will render it a most useful aid to all future 
investigators of that branch of British Paleontology. Besides these, 
which may be regarded as your special studies, you have further 
contributed to the elucidation of other fossil forms, and especially 
of some of those obscure remains of Insects and Arachnida the in- 
terpretation of which is always a matter of doubt and difficulty. In 
recognition of the value of the labours to which I have most imper- 
fectly alluded, and of your other services to the science of geology, 
and to aid you in the further prosecution of your researches, I have 
much pleasure in handing to you this small testimony of the Council’s 
appreciation. 
Dr. Woopwazp, in reply, said,— 
Mr. PREsIpENT,— 
I am fully sensible of the honour conferred on me this day by 
the Council of the Geological Society in selecting me to be one of 
the recipients of the ‘‘ Lyell Award,” and particularly grateful to 
you, Sir, for the kind manner in which you have spoken of my scien- 
tific work. There is a special pleasure in this award derived from 
the fact that in 1864 Sir Charles Lyell (then President of the British 
Association) took a warm personal interest in my first paper (read 
at the Bath meeting), ‘‘ On the Discovery of some new forms of Pa- 
leeozoic Crustacea.” If any incentive were needed to induce me to 
continue the work upon which I am engaged, it would be found in 
the kind words of encouragement which I have received from you 
to-day. 
The PrestpEnt then procceeded to read his Anniversary Address, 
which was devoted to an examination of the structure of limestones,
