Secondly, the selection of this main theme around which 
the course is organized may be determined by the chief interest 
of the author because he feels that he can present the subject 
better in this way. This fact is in no way considered a criti- 
cism and we feel that teachers should be given much freedom in 
selecting texts adapted to their chief interests.

Thirdly, there doubtless is variation in opinions as to the 
course which should immediately follow this first year science. 
At least one author states in the preface of his text that certain 
material has been omitted almost entirely in order that it 
may be taken up in a subsequent course. This is probably more 
particularly true of the biological group of sciences. 
Fourthly, it seems that few if any of the authors intend all 
of the material presented in their texts to be used in any class. 
Since the subject so easily permits of variations, it seems not 
only feasible but in some cases advisable that the indivdual 
teachers should modify the work according to their several 
needs. 
Fifthly, a comparison of the laboratory experiments ar- 
ranged by the different authors to accompany their texts re- 
veals some differences in emphasis from that made in the 
text. Additional problems and experiments which are pro-
