a surplus of about 20000 bales in favour of this year's harvest, it 

 should not be forgotten that at the commencement of the new season 

 no stocks worth mentioning of old seed were left on hand, in conse- 

 quence of which a brisk demand gave rise to a firm tendency of the 

 market. The farmers had therefore no difficulty in obtaining 17 to 

 17,75 florins for their caraway, according to quality. The tone is 

 now as before very firm, and as in the meantime the prices, with a 

 brisk demand, have advanced to 18,25 florins, it appears almost certain 

 that in the further course of the season even considerably higher 

 prices will have to be paid. 



Of Norwegian caraway but little has up to the present been 



offered, and business fell mostly owing to the exaggerated notions 



of prices held by the producers. For the present it does not appear 



probable that from this quarter a pressure on the Dutch market 

 can be expected. 



Cardamom Oil, Ceylon. When examining Ceylon cardamom 

 oil, Wallach 1 ) found a hydrocarbon (d 0,846) boiling at 165 to 167 , 

 which with glacial acetic and hydrochloric acids yielded terpinene 

 dihydrochloride (m. p. 5 2 ). The surmise that it was a question of 

 s a b i n e n e was confirmed by oxidation of the hydrocarbon with 

 potassium permanganate to sabinenic acid (m. p. 56 to 57°). It was 

 found that in the case of impure sabinene sabinene glycol was less 

 suited for the identification of sabinene, than sabinenic acid, as impurities 

 easily interfere with its crystallisation. 



The correspondingly boiling fraction of oil of marj oram also yielded 

 on oxidation sabinenic acid, and consists therefore of sabinene. The 

 presence of terpinene (which had already been detected previously 

 in the two oils) may, since the presence of sabinene in the two oils 

 has been proved, be probably attributed to a conversion of this hydro- 

 carbon into terpinene. 



Oil ot Carrot Seed. We have lately distilled an oil from the 

 German fruits (not rasped) of Daucus Carota L., and found that its 

 constants differed somewhat from those of the oil obtained in previous 

 years. The brownish-yellow oil which possessed only to a slight extent 

 the characteristic odour of carrots, was obtained in a yield of 1,26 °/ , 

 and had the following constants: di.50 0,9440; «_o — I3°5'; acid no. 2,2) 

 ester no. 17,8; ester no. after acetylation 77,5; soluble in 1,8 and 

 more vol. 80 per cent, alcohol. 



The constants of oils previously distilled by us were : — 

 Distillate of 1902: d^o 0,9226; «d — 23°i6 / ; acid no. 4,6; ester 

 no. 30,6; soluble in 4,5 and more vol. 80 per cent, alcohol.
