of ‘ Kampferharz,’ the odour being very similar to that of Camphor, 
and at the same time resembling that of Rosemary. It occurs either 
in brownish-yellow, almost pulverulent masses, or in nearly firm 
pieces, of the colour of cherrytree-gum, and looking like ordinary 
pitch ; in both states it has the same pleasant odour. It is brittle, 
translucent in thin films, becomes strongly electric when rubbed, 
and has a conchoidal fracture. Its hardness is 1°5, and its specific 
gravity 1:2—1:5. Its composition, excluding 0°84 per cent. of 
ash, is, according to Dr. Wittstein, as follows :—Carbon 81°89 ; 
Hydrogen 11°73 ; Oxygen 6°38=100:00,. This corresponds to the 
formula C,,H4,05, and shows the resin to be most nearly related 
to that from Giron in New Granada, which was analyzed by 
Boussingault ;* but it is distinguished from that species by its 
aromatic smell, and its being very easily soluble, without leaving 
any residue, both in alcohol and ether. The author then proceeds to 
give in more detail the effect of chemical reagents and solvents upon 
the resin, and states that, as he cannot reconcile its behaviour under 
their action, nor its peculiar smell, with the characters of any known 
species, he ventures to bestow upon it the name of Lwosmite. 
Euosmite is generally found filling up clefts and rents in the 
lignite, in such a manner as to leave litle doubt that the wood form- 
ing the lignite belonged to the tree which produced the resin. A 
microscopic examination of these pieces of lignite has shown that it 
consists of coniferous wood very similar to that of Cupressinoxylon 
subequale, Goeppert, and doubtless belonging to a closely allied 
species, with the characters of which Dr. Giimbel concludes his 
-paper.—H. M.J.

HIS number of the Jahrbuch contains six original memoirs, 
besides the usual miscellaneous matter. ‘The first two papers 
are by Dr. Geinitz, forming additional contributions towards a com- 
plete history of the Permian fauna and flora; they are :— 
1. ‘ Paleosiren Beinerti, Gein., Ein neues Reptil aus der unteren 
Dyas von Oelberg bei Braunau’ (Paleosiren Beinerti, Gein., a new 
Reptile from the Lower Dyas of Oelberg near Braunau). 2. ‘ Zwei 
Arten von Spongillopsis, Gein.’ (Two species of Spongillopsis, Gein.) 
These papers necessarily consist almost entirely of detailed descrip- 
tions of the fossils; it will therefore be sufficient to state that Palzo- 
siren Beinerti is considered by Dr. Geinitz to be most nearly allied 
to the existing Salamander— Siren lacertina, L., and the two species 
of Spongillopsis (S.dyadica and S.carbonica) to the living Spongilla 
fluviatilis, Blainv. 
The remaining papers are the following :— 
3. ‘Ueber die Stellung des “Terrain a Chailles” in der Schichten- 
folge der Juraformation’ (On the stratigraphical position of the 
‘Terrain a Chailles’ in the Jurassic Formation), by M. Peter Merian.
