 from Sherrin ; 50 Mosses of Malay Archipelago, from

Among the acquisitions by purchase special mention 

 should be made of the collection of Marine Algae made by the 

 late E. A. L. Batters, consisting of more than 10,000 British 

 and 3,000 foreign specimens, and more than 3,000 microscope- 

 preparations. The slides add much to the facilities for 

 studying the Algae ; and the whole collection affords a good 

 representation of the work done in recent years towards 

 ascertaining the distribution of the species around the coasts 

 of the Bi'itish Islands.

Demonstrations on the collections have been given by 

 Mr. Britten to 27 members of the Geologists' Association on 

 March 16th, and to 9 members of the Battersea Field Club 

 on November 9th ; and on the exhibition of Memorials of 

 Linnaeus by Dr. Rendle to members of the Selborne Society, 

 and of the Ealing Science and Microscopical Society, on 

 November 23rd.

The number of visits to the Department for consultation 

 and research during the year was 2,245. Numerous specimens 

 and small collections have been named by the staff for
