BIOLOGICAL NOTES. 



The Ocean Food-Supply. — The food-supply of the ocean 

 consist of a few species of unicellular microscopic plants, and 

 of a few simple protozoa which feed upon them. This supply 

 is inexhaustable and it is the only source of food for all the in- 

 habitants of the ocean, except a few which live upon floating 

 sargassum and the littoral alga), and the drainage from the 

 land. — Brooks. 



NEW PUBLICATIONS. 



The Microscope ; its construction and management, by Dr. Henri 

 Van Heurck. English edition translated by Wynne E. Baxter. 

 London and New York, 1893, pp. 382, figures 250. Royal 8.° 



As illustrative of the art of printing, this volume is exquisite; 

 everything about it is superb. But we are especially interested 

 in the subject m.atter. 



Written in French before the Antwerp Exhibition and trans- 

 lated since that event, certain improvments and additions were 

 made in the English edition. That the translator has satisfied 

 the author abundantly appears from the preface by the latter 

 who writes in praise of the work. For Americans then, the 

 English edition alone is desirable.
