1911] Proceedings. 89 



Dr. A. B. Plowman of Carroll College, Waukesha, gave the even- 

 ing's lecture on The Public Museum as a Factor in Popular Education. 



Because of the lack of a quorum no business could be transacted. 

 But owing to the necessity of having a Treasurer for the Society, as 

 urged by Dr. Dernehl, Dr. Barth and Mr. Muttkowski, President Barth 

 appointed Mr. Herman B. Beckmann as Treasurer pro tern, until a 

 Treasurer could be elected in the regular way prescribed by the by- 

 laws. 



President Barth then thanked the lecturer for his interesting 

 paper. 



The resignation of Mr. Colles as Chairman for the Committee on 

 Programs for Section Meetings was submitted. President Barth 

 appointed Dr. Robert G. Washburn to fill this place on the committee 

 for the present. 



Upon motion the meeting then adjourned. 



Milwaukee, June 8, 1911. 



Meeting of the combined sections. 



Mr. Teller in the chair. Mr. Burrill as Secretary pro tern. 



Minutes of the last section meeting read and approved. 



Dr. R. G. Washburn gave a demonstration of the hookworm and a 

 review of its life history with notes on its ravages in man. Dr. C. W. 

 Stiles brought the matter to public attention by his publication in 

 1902. This lazy-worm disease is prevalent in rural districts only. 

 Infestation is by embryos getting through the skin, not by the mouth 

 in drinking water as once thought. It comes to infest all people 

 having to do with the soil. General debility follows. Worms are not 

 fixed like tape-worms but move about, biting holes here and there, 

 giving anaemia. Also they may give off a poison in the blood, 

 increasing debility. There may be a few or thousands of worms in 

 one person. Thus has been produced the class of the south called 

 "■poor white trash". The hookworm is a member of the Nematode fam- 

 ily Strongilidd!. \t differs from its European relative Ancylostoma 

 (la oil emit a by the lack of holding hooks and fleshy lips. 



The paper was discussed by Messrs. Burrill, Monroe, Washburn 

 and Miss Elmer. 



Mr. Burrill read a paper on the "Lake Flies (CMronomus plu- 

 mosu8) and their August Swarming About Lake Winnebago". This 

 paper was discussed by Miss Elmer, Mr. Teller and Mr. Ralph.
