a silver white colour, broad foliated fracture, and shining me- 

 tallic lustre, from Riddarhytta, and found it to be a telluric bis-

17. Vesuvian of Mussa. — According to Dr Kobell, in Kart- 

 ner^'s Archiv. b. vri. heft. 4., the Vesuvian of Mussa contains 

 Silica 34.848 ; Alumina 21.933; Lime 33.609 ; and Oxydule of 

 Iron 5.400 = 97.790. — Vesuvian of Montzmii^ Silica 37.644; 

 Alumina 16.688; Lime 38.240; Oxydule of Iron 6.420 = 

 98.972. Rather more than 1 per cent of phosphoric acid was 

 found in these Vesuvians ; but whether it was a regular or acci- 

 dental part, was not determined. 



18. Garnet. — Kobell in Karsten's Archiv, b. v., in a Me- 

 moir on Garnet, maintains, that cinnamon-stone, the Hessonite 

 of Haiiy, is a variety of garnet, and is disposed to consider Kel- 

 vin also as a variety of garnet. The hyacinth-red, and orange- 

 red garnets of Piedmont, he says, are crystallised varieties of 

 cinnamon-stone. 



19- Natural Alum. — Professor Breithaupt has met with na- 

 tural alum crystallized in regular octahedrons, in a slaty-clay, 

 near to Wetzelstein in Germany. — Kdrsten, Archiv, h. vii. h. i.

20. Entomology. — -The Highlands of Scotland are rich in 

 insects. Last summer, Mr John Curtis, the editor of British 

 Entomology, made a six weeks tour in Scotland ; and among 

 the Lepidoptera alone he added to his cabinet, which already 

 contained 1200 British species, thirty species that were new to 

 him, and no fewer XhoiXi thirteen of these non-descrlpt. At the 

 base of Shehallien he found the rare Biston trepidaria. 



21. Mastodon found in Bahama. — In a collection of objects 

 of natural history, lately sent from Bahama to Professor Jame- 

 son, there is a fossil grinder of a mastodon, the first instance we 

 recollect of the remains of that genus having been found in that 

 quarter. 



22. Mammoth at HudscnCs Bay. — Professor Jameson has in 

 his possession a fine fossil grinder of the mammoth, which was 

 found on the shore of Hudson's Bay, by the then Chief of that 

 country, William Auld, Esq.
