tlielr respective neighbourhoods, and would affix to the 

 specimen a statemeiit of the exact circumstances aud tliick- 

 ness of tlie bed. The sinaller the specimens are, the better, 

 if they show the characteristic structure of the rock. 



With regard to existmg Plants and Animals, several 

 considerable improvements In arrangement and additions to 

 our coUectlon have been made during the past year. The 

 Herbarium is in good order, but it only contains 700 out 

 of 1600 British flowering plants. If any person wishes to 

 con-espond with the Society for the sake of exchange, or 

 in Order to benefit us, a marked catalogue will be supplied 

 him by the curator. We have no Cryptogamia, except a 

 good collection of ferns and sraaller marine algaj ; and the 

 microscopic forms of vegetable life are altogether wanting. 



The only portion of our collection which is in a satisfac- 

 tory State, as regards the lower Orders of animal life, is the 

 cabinet of British Shells. Of these we have 270 out of 

 about 400 species. A simllar arrangement may be made 

 with regard to these as I have mentioned with regard to 

 our collection of flowering plants. 



Of the Sponges, Zoophytes, Polyzoa, Echlnodermata, 

 and Annelids, we have next to nothing ; but the collection 

 of Crustacea formed by the late Mr. Baker has been put in 

 Order, and, though small, forms a nucleus for a more com- 

 plete set. 



Arrangements have been made for the gradual fox'mation 

 of a complete serles of Insects. A considerable number of 

 species have been procured by Mr. Parfitt, and arranged 

 with those of Mr. Baker's collection that were worth pre- 

 serving. Additions to these are particularly requested. 



All the specimens of British Fish we possess are now 

 properly arranged and protected, in the same manner as 

 the skeletons of reptiles, birds, and small mammalia which 

 we received from the late Mr. Baker.
