acquaintance and friendship between us. Batters was not married 

 at the time when I identified the Dasya, being a student at Cam- 

 bridge. I stayed three days at Berwick with him when his aunt 

 was aw T ay, and showed him Codiolum and Cladophora arctiuscula 

 growing there, and Dictyosiphon mesogloia on the road to Holy 

 Island, where we went (four miles across the mud) to get Mertensia 

 maritima, and where I found Carex incurva. Every seaweed that 

 he had not got I gave him a duplicate of if I had one, and gave 

 him the names and addresses of all my correspondents. I intro- 

 duced him to Buffham, who in the first place came to me to know 

 what remained to be done in the microscopic examination of algas. 

 I told Buffham that the reproductive organs of several species 

 were not knowm, indicating the groups and species. This work 

 he did well, being a first-class microscopist. Indeed, he taught 

 Batters what he knew of microscopic work, and helped him to 

 choose his lenses. I also indicated to Batters, and to Traill before 

 I knew Batters, the plants that should be looked for in the north, 

 and many of these they found. Batters, having a keen eye and 

 being an excellent draughtsman (he comes of an artistic family), 

 found also several new species and described them. Concerning 

 them I gave him what help I could, and when I could not deter- 

 mine what they were, being too busy teaching Materia Medica, 

 &c, I told him to whom to send them/' 



The first important paper published by Mr. Batters was his 

 "List of the Marine Algae of Berwick-on-Tweed" (Trans. Berwick- 

 shire Naturalists' Club, 1889, 171 pp., 5 plates), in which he 

 revealed to the public for the first time what a remarkable know- 

 ledge he had already acquired of marine algae. He tells us that 

 for several years he had visited Berwick at all seasons for the 

 purpose of collecting, and that with very few exceptions he had 

 himself gathered every species recorded in the list. The excellent 

 plan of the book shows the author's capacity for marshalling 

 his facts, and the critical notes are evidence of his powers of 

 observation. 



In 



1890 he collaborated with Mr. Holmes in th& production of 

 rised List of the British Marine Algge " {Annals of Botany, 



a 4t Ee vised 



v. pp. 63-107). This was a check-list with the distribution of 

 the species broadly indicated ; and in it a new classification was 

 adopted more in accordance with the advance of knowledge, Mr. 

 Batters taking the Cyanophycea and Phceophycece, and Mr. Holmes 

 the Chlorophycea and Rhodophycece. 



His first contribution to the Journal of Botany was a " Hand- 

 list of the Algae of the Clyde Sea Area" (1891, pp. 212-214; 

 229-236 ; 274-283, with map), compiled at a time when there 

 was considerable activity in the biological research of this region. 

 In the years that followed he contributed to the Journal a number 

 of short papers treating of new or critical British algae, among 

 the novelties there described being the following genera new to 

 science: — Gonimophyllum, Colaconerna, Trailliella, Porphy rod i sens, 

 Neevea, Rhodophysema, Erythrodermis. Another new genus, Con- 

 chocelis, a perforating alga, was described in the Phycological
