THE CANADIAN ENTOMOLOGIST 199 



The publications of the Canadian Institute have appeared in 

 four principal series: The Canadian Journal (1852-1855) The 

 Canadian Journal of Science, Literature and History (new series) 

 (1856-1878); The Proceedings of the Canadian Institute (1879- 

 1890) and the Transactions of the Canadian Institute (1890-1912); 

 and one minor series, The Proceedings of the Canadian Institute 

 (new series) (1892-1904). The last has not been included in the 

 general index, but a list of the papers under authors is given in an 

 appendix. 



These volumes contain a vast amount of information on almost 

 all subjects relating to Canada and a general index has been hitherto 

 much needed. The present work satisfies this need most completely, 

 being the contents of every paper dealt with in a thorough and de- 

 tailed manner. The principal entries are in bold-faced type, and 

 indented under these are the entries of subordinate topics. For 

 instance, Ontario appears in bold-faced type and under it are more 

 than three pages of entries of subjects relating to the Province. 

 Similarly we find references to genera of animals and plants in 

 bold-faced type, followed by species in ordinary type. Cross 

 references are necessarily frequent, but have been avoided as tar 

 as possible. 



This work will be of considerable value to entomologists in 

 Canada. During the first years of the Institute's history, when 

 there were few magazines dealing with special branches of science, 

 the Canadian Journal formed one of the chief means by which 

 papers on such subjects could be published; hence we find quite a 

 number of articles on botany, entomology, ornithology, etc., in the 

 earlier volumes. These are at least of historic value and con- 

 V tain many records of importance to the faunistic student. By 

 means of this excellent index they are readily accessible, and 

 there will now be no excuse for their being ignored or overlooked 

 l)y modern workers, as has sometimes been done in the pa.st.
