EbSENTIAL OIL OF ROSES. 335 



The calyxes do not in any fhape diminifh the quality 

 of the attar, nor impart any green colour to it; though 

 perhaps they may augment the quantity ; but the 

 trouble necefTary to ftrip them rnuft, and ought, to 

 prevent its being ever put in practice. 



Luc know, May, 1787.
