talent in our apothecaries, but from the miserable drudgery to which 

 they are subjected (five year's apprenticeships), at the very time of 

 life when they should be busily employed in the chemical and phar- 

 maceutical laboratory under the eye of the scientific chemist.

 above the level of the sea. The soil is calcareous and rocky. In the 

 vallies the following plants are met with : — Swertia perennis ; Cin- 

 eraria sibirica ; Polystichura thelypteris ; Schoenus nigricans ; 

 ^QMn\xm carvifolia ; Gentia.n2i, germanica ; G. ciliata ; G. pneu- 

 monanthe; Linaria alpina. On the sides and tops of the hills the 

 fWlowing occur: — Daphne C7i<?orwm ; Cypripedium calceolus; Aster 

 amellus ; Buphtalmum salicifolium ; Iberis durandii ; Arbutus 

 uva-ursi ; Dianthus superhus ; Hieracium praemorsum; Carlina

XIV. — Ozokerite, a mineral substance. 



This substance was first noticed in 1833 by Dr. Meyer. Its name 

 was applied by Professor Glocker. It is found in Moldavia near 

 Slanik, below sandstone, near coal and rock salt. It is also found 

 near Gresten in Austria. At Slanik it occurs in irregular pieces ; 

 texture conchoidal ; fracture slightly pearly ; in thick slices the 

 colour is brown-red, and in thin slices it is brown or yellowish 

 brown. The smell is agreeable, similar to that of petroleum. It is 

 soft and similar to wax. Its density is '953 at 59°. It is soluble in 

 sulphuret of carbon, ether, naphtha, oil of turpentine, but it is very 

 little soluble in alcohol, or even in boiling alcohol. It appears, 

 therefore, to be a variety of black bitumen. It boils at 410®. It 

 consists of hydrogen 13*787, carbon 86-204, according to Professor 

 Schrotter. — Bib. Univer., May, 1836.

Penzance, ISth June, 1836. 

 Sir, — I send you herewith,as requested, some of my oxide of Tree- 

 nium, and think that it will be found to correspond with Mr. Ri- 

 chardson's, oxide of Donium.* I regret exceedingly having been
