Citronellal could not be detected. The oil from which the citral had 

 been removed contained 10,5 °/ ester, calculated for C 10 H 17 H • COCH 3 , 

 and n,2°/ free geraniol. After saponification, limonene was de- 

 tected (by the tetrabromide) in the terpene fractions. Camphene 

 could not be obtained with absolute certainty. In the higher-boiling 

 fractions linalool is probably present. The presence of geraniol was 

 proved by the boiling point, and the formation of citral. 



In a Sicilian oil of lemon leaves (Fetitgrain citronnier) Umney 

 and Bennett 1 ) ascertained the following physical constants: diso 0,873, 

 «d -j-26 ; ester content 9,4%; aldehyde content 2g°/ ; total content 

 of alcohol 38,9°/o- The first 30 /o of the product passed over be- 

 tween 175 and 180 . 



Pimento Oil. We offer only our own distillate, and have again 

 been able to reduce its price. 



Pine-needle Oils. There is a great scarcity of all kinds, as 

 far as pure original distillates are concerned. Particularly scarce is 

 the oil of Finns pumilio, the so-called "Latschenkiefer", and an exam- 

 ination of the products met with in commerce under this name has 

 led to the result that they are almost without exception substitutes. 

 Further, this oil from the "Latschenkiefer" grown in the lowlands appears 

 to be of a different character to that from the trees in the Tyrolese 

 mountains. We hope that we shall succeed in clearing up this matter 

 by comparing our own distillates, and this seems to us all the more 

 necessary, as the oil of Finns pumilio finds a constantly growing use 

 as a medicament. 



The production of the very popular oil from the Siberian pine- 

 needle, Abies Sibirica, appears to have been neglected entirely owing 

 to the internal troubles in Russia; at present it can only be obtained 

 in small parcels, which is very annoying, as the oil has become 

 thoroughly introduced. 



The oil from the needles of Abies alba is also supplied in insufficient 

 quantities, but as it is not officinal, it can in case of need better be 

 dispensed with than the oil of Finns pumilio. 



It is much to be hoped that new sources of supply of good 

 conifer- distillates will soon be opened up. 



We have recently had occasion to distil ourselves oils of Finns 

 pumilio and of the needles of Abies alba, and we give below the 

 properties of the distillates obtained by us. The distillation material had 

 been obtained from Styria, and was worked up cut in very small pieces. 



Oil from Finns pumilio. The yield of crude oil (coloured yellow) 

 was 0,41%. The oil begins to boil at 170 (746 mm.); at 203 °,
