the mol. refr. (found 56,29, calc. 53,16) pointed to the presence of two double 

 bonds, a surmise which was confirmed by the absorption of 4 molecules 2 ) 

 of bromine. The author supposes the new compound to represent an ali- 

 phatic aldehyde, to which he has given the name of cypral, and which gives 

 the characteristic aldehyde-reactions with silver nitrate and magenta-sul- 

 phurous acid. 



The higher-boiling fraction of the alcoholic extract contained a hitherto 

 unknown sesquiterpene, called cypressene by Odell, and possessing the 

 following constants: b. p. 218 to 220° (35 mm.), 295 to 300° (778 mm.), 

 d% 0,9647, [«] D20 o+6,53 o , n D220 1,5240. The mol. refr. was found to be 

 64,66 (calc. 62,55) which points to the presence of a double bond. In 

 accordance with this supposition the sesquiterpene absorbed 2 molecules 1 ) 

 of bromine. With concentrated nitric acid of moderate strength cypressene 

 yields a yellow, amorphous oxidation-product; with concentrated sulphuric 

 acid it gives a distinct red coloration. 



Oil of Thyme. Roure-Bertrand Fils -) report on an almost colourless 

 thyme oil originating from Syria. The sample contained 43% phenols (thymol 

 and carvacrol) and possessed the following properties: d 15 o 0,9120, « D — 0°56', 

 soluble in 1 vol. and more 80% alcohol. 



Turpentine Oil. An instructive review of the entire position of the 

 American turpentine trade and industry, consisting of a symposium of 

 articles written by various contributors whose office or qualifications 

 entitle them to be regarded as authorities, has appeared in a profusely 

 illustrated special number of an American periodical 3 ). It would far trans- 

 cend the limits of our Report to enter into the particulars of these, in part 

 extremely interesting, articles, and we will therefore content ourselves 

 with quoting the titles and the names of the respective authors, and giving 

 a synopsis of the principal contents of those contributions which contain 

 new information of real importance. The articles conclude with very 

 elaborate statistical tables covering recent years as well as, in part, the 

 distant past, and dealing with the production of oil and rosin, the price- 

 fluctuations of turpentine oil in the course of the last 28 years, the export 

 figures relating to both the above-named products from the year 1880 

 onwards, the exports to each country of shipment in the past 10 years 

 and the total sales and quotations of the twelve different qualities of 

 resin (WW. to B.).
