learn: if Juniperus thurifera, L. is not collected in Spain and Algiers as savin, as: for 
report?) Juniperus thurifera, L. is now known in ‘Spain: under the names Sabina Alba 
or S. Roma and appears to be used for oil-winning. The oil distilled from this plant 
had an odour like savin, but weaker, _and possessed the following characteristics: —

grown side by side with the Mentha spicata, Huds. in Germany appears to be culti- 
vated also in South Africa. A short time ago the Imperial Institute*) examined a 
sample of Mentha longifolia, Huds. from South Africa; the leaves of which yielded 
whole dried plant. The liquid colourless product of distillation possessed the charac- 
similar to English and American spearmint oil with the exception of a larger amount 
of ketones, and that doubtless it would be saleable as ae oil.

with permanganate yielded propionic acid, and with chromic acid a hexylene acid,

ester melted in the neighbourhood of 140°, the absorption of bromine amounted 
to 70 per cent. of the theory. ,y-Hexenol is identical with the alcohol’) found by
