Abstract
IN the letter from Mr. J. H. Kenneth published in NATURE of February 3, page 151, a relation is indicated between the odours of certain substances and specific gravity. If, however, we examine the boiling-points of the odorous constituents of the four oils mentioned, we find that in order of increasing vapour pressure the oils stand as follows: sandalwood (305), cedarwood (280), origanum (230), and terebene (160), the figures in brackets being the approximate boiling points. This order is precisely that represented by the specific gravity quoted by Mr. Kenneth.
