TOURMALINE. 4?1 
not only of attracting ashes from the warm or burning 
coals, but that it also repels them again, which is very 
amusing : for as soon as a small quantity of ashes leaps 
upon it, and appears as if endeavouring to writhe them- 
selves by force into the stone, they in a little time 
spring from it again, as if about to make a new attempt. 
It was on this account that the Dutch called it the 
ashes drawer." 
Since the above period, tourmaline has been found 
in Brazil ; and in Norway, Germany, France, and se- 
veral other parts of Europe. It generally occurs em- 
bedded in different kinds of mountain rock ; and, in 
these, is rather confined to single beds or strata, than 
disseminated through the whole mass of the mountain. 
A piece of tourmaline, of cylindrical form, and brownish 
grey colour, was some time ago discovered in the 
neighbourhood of Kitt-hill, near Callington, Cornwall. 
Black tourmaline, both in large and small crystals, is 
found in granite rock, in the vicinity of the Logan, or 
Roeking-stones, near Treryn, in the same county. 
When laid on a table, the tourmaline appears a dark 
and opaque stone ; but, when held against the light, it 
has generally a pale brownish hue. It is sometimes cut, 
polished, and worn as a gem ; but, on account of the 
muddiness of its colours, it is not in general much 
esteemed. Those persons who wear tourmalines set in 
rings consider them more as objects of curiosity than of 
elegance : they show them as small electrical instru- 
ments, which, after being heated a little while by the 
fire, will attract and repel light bodies. 
In the superb collection of minerals of the British 
Museum, there is a magnificent specimen of red 
tourmaline, or rubellite, which has been valued at 
lyOOOZ. sterling. It was presented by the King of Ava 
to the late Colonel Symes, when on an embassy to that 
country, and was afterwards deposited by the latter in 
Mr. Greville's collection ; with that collection it became 
the property of the British Museum.
