percentage of Carbon that they contain. One way 

 in which this is effected is by the loss of water. The 

 exact changes which occur are not known, but the 

 following formulae show how such a change might 

 be effected. The first formula shows how two 

 molecules of Glucose, 2C 6 H 12 O 6 , might be concen- 

 trated by loss of water, and form a molecule richer 

 in Carbon, C 12 H 14 O 7 ; the second how this, with one 

 other molecule of Glucose, could change to the third, 

 showing a still greater amount of Carbon. Thus
