as a teaclicr and invest ip;ator soon earnt-d for him the respect and 

 iidiniration of his students and colieayUHs. lie was elected a 

 I'ellow of tlie J.innean Society in 190.S. 



As an investigator his chief interest centred in the Sponges^ 

 on which groii|) he hecame an acknowledged iiuthority. His 

 Iteporfs on the Sponges collected hy Mr. Cyril Crossland in the 

 lied Sea were published by the Linnean Society in liJ09 and 101 1. 

 In 11*13 ihe Zoological Society of London, of which he was alsu 

 a Fellow, jtnhlished an elaborate memoir on the Classification 

 and Phylogeny of the Calcareous Sponges, written in conjunction 

 with Professor Dendy. He had nlso undertaken, but iinfor- 

 tnnatelv not completed, a lleport on the Sponges of South- 

 western Australia, for the Hamburg Museum, aiul, in (onjunction 

 with Professor Dendy, a Keport on Sponges collected off the 

 north of New Zealarul by the ' Terra Nova' Expedition, for the 

 British Museum (Natural History). His work on Spoiiges, 

 carried on with the greatest enthusiasm and with a keen insight 

 into the phylogeiietie principles of classification, was untbrtunateiy 

 interrujited hy the war, and, ns a piece of very useful war work, 

 he devoted himself to the study of Protozoology, while at the same 

 time continuing to carry on his teaching work at King's College, 

 especially for medical students. His investigations on amoebic 

 dyse;itery and malaria were prosecuted under the direction of Sir 

 Konald Koss. and at the time of liis death he was in charge of the 

 Malaria Laboratory at the 4th London (leneral Hospital, where he 

 dill an immense amount of useful routine work in blood-examin- 

 ation, besides carrying on progressive research on the malaria 

 jtarasite. It is to he feared th.it he great ly overw orked himself, and 

 tliis may have had somethiug to do with the lajtidity with which 

 he succumbed when attacked by intluenza. 



In addition to these numerous activities he had for some years 

 been res])oiisible for the section on Porifera in the ' Zoological 

 Kecord ' and had lately undertaken certain other groups for the 

 sauie publication. He was also a useful mendjer of the University 

 Board of Studies in Zoology, of which he had just been 

 elected Secretary at the time of his death. 



Mr. Bow's interes's were, moreover, by no means ccjifined to 

 zoological studies. He will long he remembered amoui^st phila- 

 telists as a leading — perhaps the chief — authority on the stamiis 

 of Siam, and his collection, valued at between two and three 

 thousand pounds, has been presented by his mother to the 

 British 3Iuseum. 



He had a reiuarkable gift for systematic iuvestigation, and the 

 loss to zoologital science occasiont-d by ins death is a \ery severe 

 one. Those who had the jirivilege of knowing him will alwavs 

 think of him as a loyal friend and an inspiring colleague. His 

 memory will he perpetuated at King's College by the Harold Kow 

 Endow nient for the Promotion of Zoological Eesearch, established 

 by his mother [A. D.]
