Your Committee thanks the authors of these valuable com- 

 munications on behalf of the members. It may be observed that 

 short notes are more frequent than usual, and it is desired to 

 express the appreciation in which this class of communication 

 is held ; those who are not able to undertake a lengthy and 

 scientific paper may still be able to add their quota to the work of 

 the Club by giving short accounts of their finds, and of the 

 methods and experiences of their investigations. 



Several new and useful pieces of apparatus often the inven- 

 tion of our own members have been exhibited and described. 

 Notice of these will be found in the reports of the meetings 

 in the Journal. 



The veteran microscopist, Mr. E. M. Nelson, as in former years, 

 has laid the Club under an obligation by his numerous and inter- 

 esting communications. In May he gave a paper on " Binocular 

 Microscopes," very fully treating the subject of the new high- 

 power binoculars. At the same meeting Messrs. Beck and 

 Messrs. Leitz exhibited samples of this class of instrument, thus 

 giving an opportunity of judging their capabilities, and greatly 

 adding to the interest of the proceedings. In November Mr. 

 Scourfield read a paper describing a new species of Copepod he 

 had found in Epping Forest. The discovery by Mr. Rousselet of 

 the sexual forms of two species of African volvox, among speci- 

 mens he had received from Dr. Jakubski of Lemberg, is note- 

 worthy. The account of the experiences of Mr. Rousselet as 

 delegate to the Havre meeting of the Corresponding Societies of 

 the British Association on the eve of the outbreak of war is given 

 in the Journal. 



In February a Conversazione was held at King's College : this 

 was much appreciated by members and their friends. It was the
