INTRODUCTION 



ou tliu Civil side, Imvu Drs. V. S. Hudson, H. C. Snuin-s, 0. Atkey, G. R. Footner, 

 S. Siiigli and N. Mfilouf of the Sudan Medit-al J )oi)artment. To Dr. Watcrtidd wo are 

 again indebted for museum speuinieus. Major W. Erskine, K. A. 51.0., while in Kiiartouiii 

 in eharge of liritish troops was most diligent iu liis attendance at the laboratories, 

 where he did much work on Widal reactions, testing the permanency of the effect of 

 anti-typhoid inoculation ou the men of the Coldstream Guards. Major J. C. Jameson, 

 Captain Harvey and Captain O'Farrell have since that time also spent much of their 

 leisure at the benches. The last named has, moreover, very kindly aided iu the 

 compilation of the Review Supplement. 



Volume />'. Turning now to the second volume, it will be found that its contents 

 range over a considerable variety of subjects. Chemistry, Entomology, Ornithology, 

 Helminthology, certain Arachnida of the Sudan, Protozoology, Geology, Anthropology, 

 Sociology and Sanitary Engineering all ehiiming attention. 



Again we are indebted to extra-mural workers. Mr. A. L. IWitler, at my request, 

 kindly furnished a useful practical paper on the grain-eating birds of the Sudan, wliich, 

 fortunately, thanks to Jlr. Wellcome, it has been possible to have illustrated in a manner 

 worthy of the text. Dr. Leiper,' for the second time, favours us with an account of 

 Sudanese parasitic worms, and Professor Werner, of Vienna, witli a most interesting paper 

 on scorpions and annulated spiders which, with its fine illustrations, cannot fail to 

 be of value. Sir Thomas R. Fraser, of Edinburgh, has very kindly given us a paper 

 on the venom of the Sudan " Spitting-Snake," and Mr. Henry Curtis has written an 

 account of the " Spitting-Snakes " of South Africa, which is illustrated by drawings made 

 by Lady Dorothy Stanley. Mr. Duuu contributes an interesting account of ancient 

 gold mining in the Sudan and Mr. F. V. Theobald notes on two new mosquitoes. 



Dr. Aders' paper has been mentioned, and Captain Anderson, whose monograph on medical 

 customs in Kordofan was one of the features of our last Report, has again put pen to paper 

 on our behalf, and contributes a most interesting paper ou the Nyani-nyam and Gour people 

 inhabiting tlie Eastern Bahr-El-Ghazal. The chief anthropological interest is this year 

 supplied by Dr. C. G. Seligmann's paper. He and Mrs. Seligmann, iu 1908-9, were given 

 the laboratory steamer for their journey south, and in return Dr. Seligmann has kindly 

 become a contributor, dealing with subjects on which he is a well-known expert. 



Finally, Messrs. W. H. McLean and G. E. Hunt, of the Gordon College, who have 

 aided me so greatly in the public health work of the city, have compiled a practical 

 paper on such aspects of tropical sanitary engineering as are likely to appeal to those 

 who have to cater for the sanitary ueeds of towns in tropical countries, and which 

 should be most useful to Medical Officers of Health, Sanitary Inspectors, Municipal 

 Engineers, Boards of Health and other local Sanitary authorities, at least such as have 

 to work iu hot, dry and dusty countries like the Sudan. 



Turning now to the work of non-medical members of the Staff, one linds that 

 Mr. King has been most assiduous in his undertakings. As, at the beginning of his 

 report, he gives an outline of what he has accomplished, wdiere he has been and what 

 he intends to do, I need not enter into details, but content myself with sajTug that 

 Mr. King is a very valuable asset to the Sudan, and that every facility should be given 

 him to make the most of his keen interest in, and sound knowledge of, his sui)ject. 



I need merely refer to his researches on the bionomics of Tabanida;, which are now 

 ' Unfortunately the paper by Dr. Iicipcr was not received in time for publication.
