His contribution to the Transactions of 1889 — "List of the 

 Marine Algae of Berwick on Tweed " — first revealed to the 

 Club his remarkable acquaintance with this unexplored province 

 of Natural History. His admirable method in marshalling 

 facts bore witness to the possession of great mental capacity, 

 and his critical notes likewise attested his wonderful powers 

 of observation. In 1890 he collaborated with Mr E. M. Holmes 

 in the production of a " Ke\ised List of the British Marine 

 Algie"; and in 1902 he published his most valuable contribution, 

 entitled " Catalogue of the British Marine Alga?," in a Supple- 

 ment to that veai-'s issue of the "Journal of Botany," in 

 which is supplied a list of all the species of Sea-weeds known 

 to occur on the shores of the British Isles, with the localities 

 of their occurrence. So great was his diligence in a comparatively 

 short life that his Herbarium is estimated to contain upwards 

 of 10,000 British specimens, besides 3,000 exotics ; and these 

 along with his manuscripts have been lodged in the British 

 Museum with a view to their acquisition. 



Mr Batters was of a kindly, modest, and unselfish chsposition, 

 which endeared him to his relatives and associates, who deeply 

 deplore his premature death. His name meanwhile is com- 

 memorated in the genus Batter sia founded by Ileinke in 1890 

 upon a Ralfsia-Vikc, brown Alga of the family Sphacelariacece, 

 collected near Berwick.
