Dr. Maccullock’s account of the Hebrides is nearly fin~ 
ished.* . 
Jameson’s Philosophical Journal is much devoted to 
Mineralogy, and the numbers which have appeared do him 
great credit. 
Heron de Villefosse has been enlarging his work, and his 
Geological Map of Saxony and the North of Germany is 
said to be very fine. 
Berzelius has lately been at Paris and republished his 
new system. : 
Von Buch is busy with his work on Teneriffe in which 
many interesting discussions on Volcanic products will be 
introduced. ‘The Baron lately dislocated his arm in leap- 
ing from a German stage coach. 
Mr. Jameson has published his Vew system of Mineralo- 
gy, after the external characters only; but there are about 
thirty new substances, he has not mentioned: his Geology 
is not yet out. - 
Mr. Greenough is now the chief man of the Geological 
Society, and is preparing a Geological Map of England ; 
but what shall we think of his late small work comprising 
the best observations of a Von Buch, Brongniart, &c. (with 
others of less weight) in which he expresses the opinion, that 
there is nothing constant in Geology, and that there is no _ 
stratification of rocks ! 
Bakewel is the principal teacher of Mineralogy in Eng- 
land. 
- Mr. Brocehi’s work on the Appenines, and especially on 
the petrifactions, is fine. 
Mr. Blainville’s determination of the impression of fishes, 
in a periodical work, will be useful. 
Specimens from China, the Cape, India and Senegal are 
now most prized in France, and many of much interest have 
been received. : 
At the Cape there is Mica Slate with granite veins. In 
Senegal much Iron stone, probably in a red sand stone 
formation. : 
Our Chromate of Iron is not likely to be much prized 
now, as Dr. Heber found plenty in the Shetland Islands, of 
which he is about publishing an account.
