The rearing of insects from the egg is the next snbject. Here we 

 find full instructions for carrying on successfully this fascinating work. 



The directions for packing and transmitting insects are short but 

 complete, and it vi^ould be well if many that are not merely amateurs 

 would read them carefully and carry them out. 



A useful appendix (o this manual is a list of text books and other 

 entomological works, with suggestions as to the best Avay to obtain them. 



The publication of this book must, we believe, be followed by a 

 largely increased interest in the study of insect life, as we feel sirongly 

 that the chief reason why so few young people, both boys and girls, on 

 this continent have not had their eyes opened to the charms of this 

 branch of Natural History, to say nothmgof its usefulness, is the want of 

 such a help as Prof Riley has now provided in this concise, complete, 

 and plainly written manual. 



The Orthoceratid.^ of the Trenton Limestone of the Winnipeg 

 Basin, by J. F. Whiteaves, (Trans. Roy. Soc. Can., Vol. IX, 

 Section IV., pp. 77-90, 1892.) 



This paper as the author indicates " consists of a critical and 

 systematic list of the Orthoceratidce at present in the Museum of the 

 Geological Survey of Canada from the formation and region indicated 

 it its title, with descriptions of such species as appear to be new." The 

 specin)ens were obtained, for the most part, by officers of the Geological 

 Survey of Canada: Dr. Bell, Messrs. Tyrrell, Weston, Dowling, Lambe 

 and also by a number of gentlemen interested, e.g., Messrs. Donald 

 Gunn and A. McCharles, the last mentioned having sent unusually fine 

 specimens in 1884. 



In this paper Mr. Whiteaves departs from the classification of 

 Cephalopoda by Karl Zittel and considers the genera Adinoceras and 

 Sadoceras as distinct from Ofthoceras, and Pofcrioccr as irom Gomphoceras. 

 The characters of the specimens examined by Mr. Whiteaves and the 

 grounds upon which that author separates these genera are in our 

 estimation valuable and valid.
