$. Collecting, Mounting and Examining Objects, &c.* 



Hunting for Amcebse.f — Dr. J. E. Taylor has found the following 

 simple device for catcliing Amcehse to be successful in the highest 

 degree. He lowers one of the ordinary shilling glass troughs to the 

 bottom of the fresh-water aquarium, and when the trough has been 

 immersed about twenty-four hours, on being carefully brought up, 

 numerous Amcehse will be found crawling on the inner surfaces of the 

 glass. 



* This subdivision contains (1) Collecting Objects; (2) Preparing, (a) in

 (4) Cutting, including Imbedding and Microtomes ; (5) Staining and Injecting ; 

 (6) Mounting, including preservative fluids, cells, slides, and cabinets ; (7) Ex- 

 amining objects, including Testing ; (8) Miscellaneous matters.
