C4HaQ"03-34-H2=MannUe; and - 



Several other compoimds of sulphur with C^H^ do not taste sweet. 



The following sweet bodies, one possessing a multiple and the 



other nearly a multiple of the number of atoms in glycocollj do 



not readily admit of being written in the above formula

In reply to the inquiry as to whether sweetness may be as- 

 cribed to a peculiarity of form, the following facts are of sig- 

 nificai^ce :
