AGRICULTURAL BOOK REVIEWS

itself has assumed a bulk that precludes send- 

 ing- the student to original sources except in 

 those instances when they are themselves to 

 become mvestigators. The demand on the part 

 of the layman for concise information about 

 the new food factors is increasing and worthy 

 of attention. For all of these reasons it has 

 seemed worth while to collate the existing data 

 and put it in a form which would be avail- 

 able for both student and layman. Such is 

 the purpose of the Vitamine manual. 



No apologies are made for data which on 

 publication shall be found obsolete. The whole 

 subject IS in too active a state of investiga- 

 tion to permit of more than a record of events 

 and their apparent bearing. Whenever there 

 13 controversy the aim has been to cite oppos- 

 ing vievvs and indicate their apparent value, 

 but with full realization that this value may 

 be profoundly altered by new data. Attempt 

 has been made to cover all the important con- 

 tributions up to April, 1921. Opportunity has 

 permitted the inclusion of certain data of still 

 later date and undoubtedly other important 

 papers of earlier date will have been over- 

 looked.— Publishers' note

 He also dwells on the official and private or- 

 ganizations, including the research bureaus, 

 with which the farmer comes in contact, the 

 torms of government, taxation and educational 

 provisions. 



Most of the charts in the book are repro-
