254 THE PLANTS OF THE GRAMPIANS. 
down the temperature of springs, there are some data in my 
note-book, which may illustrate the summer temperature of 
the earth and atmosphere, in a general way. If, on examina- 
tion, they prove adequate to this object, I may offer a few 
pages upon the subject to the readers of this Journal, in some 
future number. Meantime, the result of observations made 
several years ago may be seen in the Magazine of Natural 
History, seventh volume, page 444, or in my small volume 
published under the title of “Remarks on the Geographical 
Distribution of British Plants,’ pages 27—30. Numerous 
notes of temperature made on the Grampians, in 1841, will 
carry forward that branch of the subject somewhat farther, 
when compared and reduced into methodical form, which has 
not yet been done. 
On the Position to be assigned to the Genus Cneorum in the 
Natural Series. By P. B. Wess, Esa. 
It has long been a matter of doubt to what Class among its 
congeners the little group of Cneorum, containing, even now, 
only two forms, can be rightly referred. To the older of 
these Linneus applied the name of Cneorum, though it was 
neither the xvéepov, of Theophrastus, nor the @vpedaia or 
xvéupov of Dioscorides, species of Daphne, (Daphne Gnidium 
and Daphne oleifolia ?) the former of which yielded the once 
well-known Gnidium Granum, It may possibly have been 
one of the plants confounded by Pliny under the names 
Thymelea, Chamelea, Cneorum, and Oleastellum; it is not 
however a native of Greece or Asia, nor, properly speaking; 
of Italy. To this, (the Cneorum tricoccum, L.) Ventenat 
added a second species, Cneorum pulverulentum, raised in the 
garden of Cels, from seeds sent by Broussonet from Tene- 
riffe. When Jussieu arranged all the known genera in Natu- 
ral Orders, he placed Cneorwn in the second section of his 
Terebinthacee, a provisional union, as he himself declares, 
the component parts of whieh have been variously divided, 
and classed by subsequent botanists. None however have
