The composition of the pure fruits and fruit juices used as the basis 

 of the fruit products is of great value in interpreting- the results 

 obtained in the analysis of these various materials. To meet this need 

 Tables 9 and 10 have been compiled, the first giving the averages of 

 analyses of whole fruits, the second of fruit juices. In addition, a 

 large number of analyses of the fresh fruits and juices have been made 

 by the writers, results of which are given in Tables 11 and 12. While 

 the analyses compiled in Tables 9 and 10 are incomplete in man}^ 

 respects, they give a fair idea of the proximate composition of nearly 

 all the fruits dealt with in the bulletin. It was not attempted to make 

 this compilation complete, Onh' such anah\ses as seemed of particu- 

 lar value in aiding the interpretation of analytical data are included. 

 It must be remembered that these analyses are of samples from 

 extremely variable sources, and as a rule represent a large number of 

 varieties, hence a wide variation in their composition is to be expected.
