 seven papers devoted to botanical subjects, 

 ten to zoological and histological topics 

 and fifteen to technical subjects relating to 

 the manipulation of the microscope, its ac- 

 cessories and the material to be examined. 

 Titles of some of the more important papers 

 were the flagella of motile bactei-ia, by Dr. 

 V. A. Moore, of Washington; corkj' out- 

 growths of roots, by Herman Schrenk, of 

 St. Louis ; the secondary thickenings of the 

 rootstalks of Spathyema, by Mary A. ISTieh- 

 ols, of Ithaca ; the history of the sex cells 

 from the time of segregation to sexual dif- 

 ferentiation in Cymatogaster, by Professor C. 

 H. Eigenmann, of Bloomington, Ind.; the 

 morphologj' of the brain of the soft-shelled 

 turtle and the English sparrow compared, 

 by Susanna Phelps Gage, of Ithaca; the

 phibia, by B. F. Kingsbury, Ph. D., of De- 

 fiance, Ohio ; the primitive source of food-

The moi-ning sessions (9:30 to 1) were 

 regularly devoted to the reading and dis- 

 cussion of papers. Following these, on 

 Wednesday afternoon the Society inspected 

 the library and other university buildings 

 and witnessed the ruling of micrometers 

 with a Eogers dividing engine in the phys- 

 ical laboratory. In the evening President 

 Gage delivered the annual address before 

 the Society. 



On Thursday afternoon the Society was 

 treated to an excursion on Cayuga Lake by 

 the citizens of Ithaca. The enjoyment of 

 this excursion was greatly increased by the 

 kindness of Professors Tarr and Williams, 



who explained the geological formations 

 met at the various points. 



In the business session on Friday after- 

 noon the project for an international biblio- 

 graphical bureau of zoology was brought 

 before the Society by Professor H. B. Ward, 

 and it was unanimously decided to present 

 the bureau with the proceedings of the So- 

 ciety and also to grant a subsidy of $25 for 

 the coming year.
