The following terpenes, viz., d-pinene, d-limonene, and dipentene, were 

 found to occur in the oil. The borneol and its acetate contained in 

 the oil were dextrorotatory. 



Upon distilling the wood the authors obtained a thick oil containing 

 guajacol and a new phenol "callitrol". 



The sandarach resin yielded by this variety of tree was inferior 

 to that from Callitris calcarata. 



Rose Oil, Bulgarian. In order to afford a better understanding 

 of the tables relating to the production of rose oil *) which we published 

 in our last Report, we now present our readers with a map of the 

 districts where rose oil is produced, giving a survey of this interesting 

 region which has been so frequently alluded to in former Reports. In 

 this case also, we are indebted for the data upon which our inform- 

 ation is based to Messrs. S. Seraphim off & Co., of Kazanlik. 



Transactions in rose oil have naturally suffered during the past half 

 year under the general depression of trade, and if notwithstanding 

 this prices have remained unchanged, this may be ascribed in the 

 first place to the fact that at the very beginning of the last crop an 

 extremely lively interest for the article was shown on all sides. Any 

 oil which was not sold firm for delivery passed into the hands of 

 wealthy exporters, who were in a position to await the demand without 

 depressing the market with their stocks. It will be clear, without 

 further explanation, that these firms have not experienced much satis- 

 faction from the transactions in rose oil during the past six months, 

 for experience shows that when business is dull valuable articles are 

 those which excite the least desire to purchase. 



Roure-Bertrand Fils 2 ) report on an oil from white Bul- 

 garian roses. It possessed the following constants: dj.50 0,8723, 

 «b — 2° 54', ester no. 11,14, ester n o. after acetylation 222,44, 

 corresponding to 74,44 per cent, of alcohols of the formula C 10 H 20 O. 

 The oil is soluble, with strongly marked separation of paraffin, in 

 1 vol. of 90 per cent, alcohol. At -f- 14 it is solid, but at 20 it 

 liquefies completely. Its odour is much less delicate and persistent than 

 that of the oil from red roses, and Roure-Bertrand Fils therefore 

 advise that the latter only should be used for distilling purposes. The 

 fact that the white roses are the less valuable variety is also the reason 

 which, in 1906, induced the Chamber of Commerce of Philippopolis 

 to urge upon the distillers the advisability of abandoning the cultiva- 

 tion of the white roses 3 ).
