1904-1905-] Address by the President. 231 



to be taken up seriously there must be a division of labour, — 

 separate workers in many different departments. To carry 

 this out, the members should form themselves into small 

 sections, vpith a convener to each, for the study of those 

 branches of the subject to which they are more particularly 

 inclined. A place of meeting could be found at the house of 

 one or other of the members of each section, or at such other 

 place as might be arranged. Papers from the workers in these 

 various sections would be communicated to the Society at its 

 monthly meetings, and would thus appear in the ' Transactions.' 

 This would prevent the sections from drifting apart, and would 

 constitute a bond of solidarity and an esfrit de corps among the 

 members as a whole. Again, members would change from one 

 section to another, which would tend to broaden their know- 

 ledge and increase their sympathies with each other. The 

 following are some of the subjects for the study of which 

 sections might be formed : — 



Animal Kingdom: (1) Stib-Jcingdoms Protozoa and Ccelente- 

 rata. — Under these sub -kingdoms the following divisions 

 would furnish many interesting subjects for the study of the 

 lower forms of life — viz.. Amoeba, Infusoria, and Hydrozoa. 

 The following are books bearing upon these divisions : — 



' Fresh-water Rhizopods of North America,' Leidy. 

 ' Manual of the Ccelenterata,' Greene. 

 ' Manual of the Infusoria,' Saville Kent. 

 ' British Zoophytes,' Pennington. 



(2) Crustacea. — Under this division, and particularly under 

 the sub-class Entomostraca, there are a very large number of 

 genera, specimens of which are easily obtainable, and having 

 this additional advantage, that the life-histories of many of 

 them can be studied without much difficulty. Eeference to 

 the following books may be made: — 



' Natural History of British Entomostraca,' Baird. 



' Report on the Present State of our Knowledge of Crustacea,' Spence 



Bate. 

 ' The Crayfish,' Huxley. 



(3) Arachnida. — These include the spiders, mites, &c. The 

 following books may be consulted : — 



' British Spiders,' Staveley. 

 ' British Oribatidae,' Michael. 



There are also some in German on special genera.
