In addition to laurinic aldehyde, a second aldehyde appears also 
to be present in the oil of Abies pedinata, which we would designate 
as decylic aldehyde. At least, we obtained as the first runnings of 
the above-mentioned principal fraction, about 1,8 gm. of an aldehyde of 
the boiling point 94° to 108° (5 mm pressure) which had a distinct odour 
of orange oil. Its semicarbazone melted at 93° to 95°. We endeavoured 
without success by fractional crystallisation to obtain the body sufficiently 
pure for analysis, but we could ascertain from the combustions that the 
derivative consisted chiefly of the semicarbazone of laurinic aldehyde. 
Rose Oil. Since our last Report, business in this important article has 
been so slow, that on the whole the prices since the harvest have scarcely 
advanced by as much as the normal rate of interest. The enormous yield 
of the harvest has frustrated the contemplated manipulation of the prices 
by a few speculators, although the lifeless condition of the market is 
also in part attributed to the uncertain political situation in the Balkans. 
The normal state of affairs in the rose oil trade has, according 
to our experience, become worse rather than improved, for we have 
not in any previous year encountered the same difficulties as this year 
in finding faultless qualities. 
The following figures of the exports of 1903 show^ a considerable 
increase, as compared with the export of 1902; about half of this is 
due to speculative enterprise, which cannot cause surprise in view of 
the low quotations.
