NOTfiS AND QUERIES.

successively sunk for upwards of a century, and the belief generally prevails 
ill the district that the combustible substance is there. 
2. What, and where, are the correlates of the fossils now detected here for 
the first time ? I have lying on the table while I write a specimen from Links- 
field, near Elgin, of the " Cypris globosa bed" of marls, and which, from these 
and other organisms, are generally regarded as belonging to the Triassic and 
>he Wealden. My eye detects no difference in either the character of the 
matrix or the forms and contour of the Crustacea organisms in the Dron and 
the Elgin specimens. Both are of the same thickness, the same colour, the 
same shelly texture, and the Entromostraca are numerically the same in the 
composition of the respective deposits. Further researches may possibly unfold 
more resemblances. 
3. The student of physical geology will find much to interest him in the 
district ; in the general structure and variety of the trappean formations, the 
vast accumulations of drift in the strath, the boulder clays along the slopes*of 
the hills and in the lateral valleys, and the various ravines formed by the moun- 
tain streams by the incessant and ever-wearing action of ages. Bat Glenfarg 
will form one of his chief attractions, from its many natural beauties and ex- 
uberant richness in many rare minerals. The entire family of Zeolites are 
there : — Tkomsonite, Stilbite, Datholite, Heulandite, Analcime, Preh/iife, and 
the newly analized Fargite, long described as Galeatite from its extreme 
whiteness. — Dr. Anderson, Newburgh, Eifeshire. 
Fossil Trees at HaughlInd. — A short time since when Mr. William Young, 
builder, Bisliopmill, was digging a well at Haughland, near Palmercross, a very 
unexpected discovery was Made. First, in digging the well, the workmen cut 
through two feet of good mould, a depth of soil of which many of our farms 
would be glad. There was then soft sand mixed with some clay for other five 
feet d6wnwards. This was followed by six inches of moss, then six inches of 
sand underlying the moss, and these three strata were followed by a bed of 
strong blue clay eighteen inches or so in thickness. Next came two feet and 
a-half of black moss at the depth of nearly ten feet from the surface, and here 
was found a birch tree with its branches, some of them four inches in diameter, 
embedded in the moss, lying along as they had been laid when the tree was 
uprooted. A great part of the tree was in a comparatively good state 
of preservation, and when pressed the water oozed through it like a sponge. 
It is hard, black, and of course very heavy. We may remark that this fossil- 
tree grew ten feet beneath what is now the river Lossie, which flows within 
two hundred yards of the spot where it was found. Geologists are agreed that 
the great plain extending from Aldroughty to Birnie was once covered by a 
lake, but the tree found beneath the bed of blue clay shows it was a forest 
before it was a lake, and the bed of sand both above and beneath the moss in 
which the tree was found strongly favours the belief that the land in the plain 
meiitioned has been oftener than once submerged by the sea. 
The Minerals of the Metallic Veins of Frieberg. (Extract in the 
Annales des Mines, by M. Delesse, from the article " Die mineralien der Frei- 
berger Erzgange Zusammengestellt, von C. Weiss, mit Bemerkungen von Bern- 
hard Cotta," in the Berg und Huttenmanmsche Zeitung, 1860. Translated from 
the French by H. C. Salmon, F.G.S., F.C.S.) — I have proposed to myself to 
compare the mineralogical composition of the metaUiferous veins of Freiberg 
—a task which has been accomplished by the aid of the numerous documents 
posscFsed on this subject, and by the assistance of one of my pupils, M. Weiss. 
It is summed up in the following table, which gives the mineralogical composi- 
tion of our four systems of metalliferous veins. The minerals most frequently 
met with are inserted in italics.
