Rosemary Oil. The prices for French as well as for Dalma- 

 tian oil have become decidedly firmer in the course of the last few 

 months, and in the districts of production the supplies are beginning 

 to lessen. On account of the low value, the oil has gained numerous 

 new consumers, especially the French kind, and it is likely that the 

 market may shortly acquire increased firmness. 



We have already previously referred to the observations of Bircken- 

 stock 1 ) with regard to the changes, according to the season of the year, 

 in the composition of oil of Rosmarinus officinalis L. 2 ). 



Rue Oil. We have already on a previous occasion referred to 

 an article byBirckenstock 3 ) on the effect of the season upon the oil 

 contained in Algerian rue 4 ). 



From Corfu we received offers of two oils of sage, which possibly 

 were not derived from Salvia officinalis L., because, in contradistinction 

 to ordinary oil of sage, they were laevorotatory. The odour also 

 was different, thujone being less perceptible. The constants of the 

 pale yellow, almost colourless distillates, were as follows: — 

 di5° 0,9153, «r> — 15 14', acid no. 0,5, ester no. 9,0 

 „ 0,9132, „ — 1 5 5', „ „ 0,5, „ „ 10,6 

 The oils were soluble in 1,3 vols, of 80 per cent, alcohol and more. 

 Of 70 per cent, alcohol, about 25 vols, were needed to effect solution. 



Sage Oil. In a short paper on the present state of research in 

 sage oil, T. F. Harvey 5 ) refers to investigations by A. Tompkin, who 

 has examined one Spanish and four Dalmatian oils. The first-named 

 possessed the following constants: d 0,9053, «d -f- 9,60°, n D20° 146 19, 

 acid no. 0,6, ester no. 17,2, total borneol 15,2 °/ ; soluble in 2 vol. 

 of 80 per cent, alcohol. The values of the Dalmatian oils moved 

 within the following limits: d 0,921 to 0,9253, « D -(-9,93° to -\- 13,62°, 

 n r>20° 1,4618 to 1,4645, acid no. 1,3 to 2,2, ester no. 6,7 to 8,5, total 

 borneol 9,5 to 14,8 °/ , soluble in 1 and more vol. alcohol. The oils 

 boiled chiefly between 170 and 220°; below 170° only 2 to 3 °/ 

 passed over, between 170 and 200° 55 to 65°/ , and between 200 

 and 220° 21 to 31%. The corresponding fractions of the Spanish oil 

 were 13,64 and io°/ . We have made frequent communications 

 about oil of sage in our recent Reports, to which we may here refer 6 ).
