which occurs in the process of oxidising a-terpinene. Attempts to obtain 

 crystallising derivatives from the terpinenol, or to separate it from the 

 accompanying bodies in a still purer form, have so far led to no re- 

 sult. Another alcohol occurs in juniper oil in addition to terpineol, 

 but in far smaller proportions than that body. This alcohol possesses 

 the following constants: b. p. 105 to no° (8 mm.) 218 to 226° at 

 atmospheric pressure, d i5 o 0,9476, «d — 4°3°'> n r>22° 1,48248. It com- 

 bines readily with phthalic acid anhydride, and was isolated from the 

 fractions boiling between 95 and 130 in the form of the acid phthalic 

 ester. In its odour the alcohol reminds of geraniol and borneol, and 

 it is probably a mixture of various alcohols. Besides the compounds 

 enumerated above, juniper oil contains bodies of a particularly 

 characteristic odour, most of which occur in small proportions in the 

 fraction boiling between 72 and 88° (8 mm.). 



Oil of Lantana camara L. ^. According to Bacon 2 ), the parent 

 plant of this oil, which belongs to the Verbenacecz and possesses a 

 pleasant odour, flourishes with such extraordinary profusion in the 

 Philippines that it would undoubtedly pay to cultivate it. The yield 

 of oil from the leaves appears to vary greatly according to age, 

 season, etc, as from two parcels of raw material, one weighing 60 and 

 the other no kilos, the oil-yield was 0,07 and 0,245 percent, by 

 volume respectively. The oil is pale yellow, with an odour reminding 

 of sage, and has the following constants: d -^- 0,9132, a D3o° -f" 11 ^ *

 22 g., b. p. 125 to 130 (12 mm.), n D30 o 1,4892; and 24 g., b. p. 130

Last year 3 ) we described a West Indian oil of Lantana odorata L. 

 With the exception of the rotation, its properties agree closely with 

 those ascertained by Bacon for oil of La?ilana camara L. 



Lavender Oil. All reports from the departments of the Basses- 

 Alpes, Alpes-Maritimes, Vaucluse, and Drome — which are the chief 

 lavender districts — , agree in stating that in the early spring the 

 highest expectations of the success of this year's crop were being 

 entertained. During the greater part of the winter months a thick 

 cover of snow protected the vegetation from the effect of a too high 

 degree of cold, and it was therefore fair to expect a healthy deve- 

 lopment of the plants in the spring. Unfortunately severe frosts in 

 May have had an exceedingly injurious effect. The first young shoots 

 were destroyed and, owing to the continuation of unfavourable weatlier, 

 were unable to renew themselves. The drought which has prevailed
