REFERENCE BOOKS 



There should be a library of reference books for the 

 zoolog}' classes consisting of all the standard works; but 

 if such is not possible under existing conditions, the teacher 

 will often be able to get a few volumes. It is better to have 

 a few good books duplicated than to have a miscellaneous 

 collection. The following are recommended and are ar- 

 ranged in the order of their importance : 

 Jordan and Kellogg, " Animal Life." 

 McMurrich, J. P., " Invertebrate Morphology." 

 Parker and Haswell, "Text-book of Zoology." 

 Comstock, J. H., " Manual for the Study of Insects." 

 Lang, " Text-book of Comparative Anatomy." 

 Holland, " The Butterfly Book." 

 Darwin, " The Formation of Vegetable Mould." 

 Jordan, D. S., " A Manual of Vertebrates." 

 Cones, Elliott, " A Key to North American Birds." 

 Tryon, " Structural and Systematic Conchology."
