Explanatory Note 



'"T^HE object of this note-book is two-fold : to facilitate the 

 taking of adequate notes in the field, and to teach 

 accuracy of observation. 



The six outlines of animal forms represent generalized 

 types toward some one of which every vertebrate (except 

 the bird) will approximate, and which with slight changes 

 will accurately portray the species under observation. 



PLATE I A generalized fish. This with slight modifica- 

 tions, will represent any of the fresh- water 

 forms, and most of the marine species. 



PLATE II A generalized salamander. This will serve for 

 the adult and larval salamanders and newts, 

 and with modification will represent the alliga- 

 tors and the lizards. 



PLATE III A generalized frog. This will represent any frog, 

 tree-frog or toad. 



PLATE IV A generalized snake. This will represent the 

 harmless and the venomous snakes and the 

 limbless lizards. 



PLATE V A generalized turtle. This will serve for any of 

 the turtles, tortoises or terrapins. 



PLATE VI A generalized mammal. This with slight 

 changes will represent any of our smaller 

 native mammals.
