380 OBITUAKY NOTICE. 



and embrace papers on collecting and preserving material, de- 

 scriptions of new species and census lists of additions to the 

 rotiferal fauna in many parts of the world. His wide circle of 

 correspondents enabled him to considerably increase our know- 

 ledge of the geographical range in the distribution of even 

 well-known forms. His descriptive papers were always accom- 

 panied by accurate drawings illustrating the specific details 

 necessary for their determination, and in this way he set a 

 very excellent example. His methods of preserving and 

 mounting the material are perhaps better known than his 

 more descriptive work both by workers in this group and in 

 other groups of animals both marine and freshwater. Narcotisa- 

 tion either by his method or some modification of it is now prac- 

 tised in all laboratories where biological work is carried on. The 

 last paper published by him, " Some Further Notes on Collecting 

 and Mounting Rotifera," appeared in our Journal (vol. xiii. 

 Journal Q.M.C, p. 321, October 23rd, 1917), where a bibli- 

 ography is given of his various papers dealing with this subject, 

 in which he achieved such marked success. 



He served the Club for many years in the office of Foreign 

 Correspondent and also as Vice-President, and was a frequent 

 attendant at both our meetings and excursions, where his expert 

 knowledge was always freely available. He was also for many 

 years on the Council of the Royal Microscopical Society, having 

 been appointed Hon. Curator in January 1898 ; he served in this 

 office till December 1916, when his increasing physical disability 

 led to his resignation. His valuable collection of reprints, 

 numbering over a thousand items, is now preserved, for purposes 

 of reference, in the Library of the Royal Microscopical Society ; 

 they probably form a unique collection of papers on the subject 

 of the Rotifera, 



For permission to use the portrait-block of Mr, C, F, Rousselet 

 illustrating this notice we are indebted to the Editors and Council 

 of the Royal Microscopical Society.
