 soluble in 8 vol. 90 per cent, alcohol. 



As in the case of all these distillates any adulteration whatever is 

 out of the question, it will be necessary to revise the limits fixed; 

 for our part, we must for the present decline to fix definite figures 

 as the material at our disposal does not yet appear to be sufficient 

 for the purpose. 



Oil from the needles of Abies alba is again in stock in abundant 

 quantity, but the fine Swiss oil from the cones (01. templini), the 

 manufacturing season of which takes place in the last months of the 

 year, may possibly only be obtainable this year with great difficulty. 

 Although the formation of the young sprouts looked very promising 

 this spring, the trees now only carry such a small quantity of cones, 

 that it will scarcely pay to gather them. For this reason the prices 

 will have to be raised in proportion. 



It is all the more satisfactory that we are able to state that the 

 Siberian pine-needle oil finds favour with a constantly growing 

 number of consumers, who are utilising it for their purposes on account 

 of its powerful characteristic odour, and not the least on account of 

 its advantageous price. Our informants report that the distillation takes 

 place in the summer and autumn, and that orders placed in the spring 

 and summer can be executed to any extent. Only in the autumn 

 and winter it is often difficult, and occasionally impossible, to procure 

 the oil, owing to the difficulties in the transport caused by snow and 

 ice. The producing-district is in the Government Wjatka, whilst Siberia 

 itself supplies only small quantities which cannot compete owing to 

 the high cost of transport. The new railway Wjatka- Wologda-St. Peters- 

 burg has meanwhile been opened for traffic, and this route will be 

 the more advantageous One for the transport of the oil. There are 

 no difficulties of any kind which would prevent the supply of this oil 

 in any desired quantity. 



A distillate from the needles of Pinus halepensis Mill, originating 

 from Algeria, had the following properties: almost colourless; d^o 0,8643 ; 

 «d — 3 22' \ acid no. 1,3; ester no. 21,2 = 7,4 °/ ester, calculated for 

 bornyl acetate. The oil has accordingly a certain similarity to the 

 oil of Pinus purnilio, which it also approaches in respect of the odour. 



In continuation of his examinations of the essential oil of the 

 shoots of Pinus maritima Mill. 1 ), E. Belloni 2 ) detected the presence 

 of 1-borneol, by means of Tiemann and Kruger's 3 ) phthalic an- 

 hydride process. The 1-borneol obtained melted at 205 . Possible 

 deviations of his present values from those previously obtained are
