THE MICROSCOPIST IN BERMUDA. 



PAGE 



The situation, description and history of these small islands. 

 - The formation is "^Eolian," and dependent on coral 

 reefs. It is entirely organic. The life history of the 

 Foraminifera, the most numerous of the shells in the 

 sand. Life history of the Echinus, or sea-urchin. 

 Wonders and beauty of its structure as revealed by the 

 microscope. The bird's-head Polyzoa. The Hydro- 

 zoa, and their intermediate generation, the jelly-fishes. 

 The great interest there is in the Invertebrate 

 kingdom. - - 115 



MICROSCOPICAL COLLECTIONS IN FLORIDA. 



Florida peculiarly adapted to the development of air-plants 

 and of organs for the absorption of aerial nutrition. -- 

 Glandular cells, like inlaid pearls, on leaves of Onosmo- 

 dium. - Stellate scales on leaves of Croton plants. 

 Beauty and object of the scales on Florida moss. Resin 

 dots on leaves of Calicarpa and sweet myrtle. Insec- 

 tivorous plants. Drosera, or sun-dew. A new, float- 

 ing, variety. Utricularia, or bladder-wort. Pitcher 

 plant, the most wonderful instance of adaptation to 

 special purposes. Its development cannot be explained 

 under the Darwinian theory. - 131 



ON THE PREPARATION OF OBJECTS FOR 

 THE MICROSCOPE. 



Spiral tissue in leaf stem of castor-oil plant. Methods of 



staining vegetable tissues of all kinds. Methods of 



mounting in cells, both with fluids and as dry mounts. 



- The author's views on the various cements used in 



mounting. - - 145 



PREPARATION AND MOUNTING OF DOUBLE 

 STAININGS. 



A paper read before the American Microscopical Association, 

 giving a full account of the author's methods of multiple 

 staining, and of mounting the specimens both in Can- 

 ada balsam and in aqueous fluids. - 155
