16 DTFFERENTIATION AND SPECIFICITY OF STARCHES. 



other conditions nnisi be determined; the time-reactions of the effects of each reagent 

 should be repeatedly obser\'cd, as often as occasion demands, in the case of each specimen 

 under given conditions of experiment in order to establish mean standards, and so on. 

 However, if the three finidamental objects stated in the beginning of this chapter have 

 been fulfilled, and if by throwing open the shutters investigators may perceive roads and 

 pathways leading to the elucidation of the extraordinarily important relations that exist 

 between stereochemistry and protoplasmic processes, the labor has not been in vain. 



In the final arrangement of this report it has been found to be a mechanical necessity 

 to carry the detailed laboratory records into a separate volume, and these accounts now 

 compose Part II of this publication. This arrangement, it is hoped, will make this mat- 

 ter easy of reference, although the first impression may be that they have been taken out 

 of their more logical position.
