Lincoln Microscope Club, Roscoe Pound, Secretary. 



Jime 27, 1893. — On account of hot weather and absence of 

 members from the city, it was resolved to hold no more meet 

 ings till September. Dr. Philbrick showed the anthrax bacillus 

 in tissues. Prof. Bessey showed slides comparing paper from a 

 wasp's nest wiih a good quality of writing paper, also coarse 

 paper from the same nest with grocer's wrapping paper. In 

 each case the wasp had rather the best of it. Mr. Woods exhib- 

 ited slides showing the fertilization of the cell which produces 

 the resting spore in peronospora. 



QuECKETT Club, London, England. 



Friday, June 16. — 313th ordirary meeting; Mr. E. M. Nelson, 

 F. R. M. S.. president, in the chair. Mr. Karoj) said he had 

 found a somewhat uncommon diatom, Stauroneis legmnen, Ebr. 

 in a gathering made by Mr. C. H. Gill from the River Lea, and 

 he was under the impression that it had not previously been 

 recorded from this locality. 



Mr.T. F. Smith exhibited a 1-12 hom. immersion of 1. 3 N. A. 

 made by Swift and Son, which, in his opinion was but very 

 slightly inferior to the Zeiss apochromatics of the same focus. 

 Photograplis of P angidatum taken with these respective lenses 

 were shown, and the president remarked that although tbe 

 picture given by the apochromatic was slightly sharper, the dif- 

 ference was very small, and the new objective was undoubtedly 

 of excellent quality. 



Mr. Rousslet read a paper by Mr. Joha Hood, of Dundee, on 

 three new Rotifers, viz.; Floscularia spinata, Polyarthra aptera. 

 and Brachionus tridens, of which drawings were shown.
