although in the main the system of notation of the mamma- 

 lian teeth prepared by Professor Owen was a great advance

 method of determination. 



Professor Huxley gave an account of the observations 

 •which form the the subject of his paper in this Journal. 



Other papers relating to microscopical science were the 

 Rev. A. M. Norman^ s, on " A New Sponge (Oceanapia) 

 from the Shetlands/^ and on " Hyalonenia boreale of Loven." 

 That by Mr. Moggridge, on the " Muffa," appears in another 

 part of the Journal; whilst the President's (Rev. M. J. 

 Berkeley) Address we have also given in full, since it con- 

 tains a valuable review of some recent speculations in crypto- 

 gamic botany. There was, we regret to state, a very marked 

 absence in the Department of Anatomy and Physiology, of 

 papers on histological subjects. 



Medical Meeting at Oxford. — A most interesting and care- 

 fully arranged series of preparations, under nearly 120 

 microscopes, was exhibited by Dr. Lionel Beale at the August 

 meeting of the British Medical Association at Oxford. The 

 series was described in an illustrated catalogue presented to 

 each member, and formed, perhaps, the most complete histo- 

 logical exhibition ever arranged.
