tites, he had inspected many considerable collections in differ- 
ent parts of England, and collected abundance of new informa- 
tion, which he fully expected to be able to digest into regular 
order, so as to present a continuation of his report on the sub- 
ject at the next meeting. 
Mr. Stevenson’s teport on the relative Level of Land and 
Sea was read. 
NaruraAv Hisrory, 
Ar the last Meeting of the British Association, a Committee 
was appointed for procuring drawings illustrative of the Spe- 
cies and their details of the Radiate Animals of the British 
Islands, to accompany a Report of the state of our knowledge 
of such Animals, and the sum of 50/. was placed at their dis- 
vosal. 
Respecting the state of our knowledge of two divisions of the 
Radiate Animals, the Committee feel it unnecessary to furnish 
any report, these departments being undertaken by individual 
members of the Committee, whose researches are either pub- 
lished, or are now in course of publication*. With regard to 
the remaining portion, the Acalepha, they are persuaded it 
cannot be effectually investigated and illustrated, except when 
the artist and the naturalist are combined in the person of 
one individual. ‘The Committee, therefore, after an expendi- 
ture of only two pounds, now bring forward the drawings they 
have ‘had prepared, and, for the reasons assigned, beg leave 
to discontinue the further prosecution of the subject. 
Tur Committee appointed at the last Meeting of the British 
Association, for the investigation of the Marine Zoology of 
Great Britain, by means of the dredge, lave to report the ex- 
penditure of 152. out of the 50/. granted for that purpose. The 
state of the weather, which prevented dredging in the open sea 
during a great part of the summer, and the dittculty of obtain- 
ing observations sufficiently precise in information respecting 
species, have been the causes which have operated against 
them, and caused the expenditure of so small a portion of the 
grant. A series of queries, and printed formule to be filled up 
with the results of the dredging excursions, were prepared and
