We hâve nôw a fairly eomplety knowledge of Lhe Crustacea, 

 Coleoptera and Odonata, and, to a less extent, of the Rotifcra 

 and Hydrachnida, but very rnuch remains to be (loue, notably 

 with regard to lhe Mollusea, Turbellaria and Protozoa. 



WheD a gênerai knowledge of the fauna and fiora lias been 

 obtained in tliis way, ilie ground will be clear for more detailed 

 investigations into Bionomical problems, involving not only 

 the relation of groups of animais to their environment, vvhicli 

 is a work difficult, if not impossible, to dndertake withoutthe 

 continuons co-operation of workers, but also and chiefly that 

 of individual species or gênera by vvorking oui their life his- 

 toriés thorouglily. 



From L903 till the beginning of 1907 Mr. F. Balfour Brownb 

 was Director of the LaBbratory, and occupied himself willi lhe 

 studv of the distribution and life historiés of the Odonata and 

 Coleoptera. In 1907 lie lel'i to take up new duties at. Belfast, 

 and the functions of Director were assumed 1 > \ Mr. R. Gurney. 

 Mr. C. H. Martin was employed during three months of the 

 suminer of 1907 as Naturalist, and completed work already 

 begun elsewhcre on the ncmatocysts of Turbellarians, and 

 began work on the life history of an Acinetan living in colonies 

 of Cordylophora. Al preseni the Laboratory is vvithout the 

 services of a Naturalist. 



A considérable ainount of work lias beendoneon theAnalysis 

 of the waier with référence to tidal influences by Messrs. H. Peel 

 and A. (V. Innés, but the results are notyel ready for publication. 

 ( Ibservations hâve also been made from lime to lime on the tides 

 of the rivers by means of portable lide gauges, bui hère assis- 

 lance of a trained specialist in thissubjecl is particularly needed. 



A sclieme is being drawn up, in co-operalion with lhe Norfolk 

 and Norwich Naturalists' Society, for a Botanical Surveyof the 

 Norfolk Broads District, with spécial référence lo lhe aquatic 

 and marsh végétation. Il is hoped thaï good progress will be 

 made during lhe summer of lliis year (1908).
