 It is the agaric employed for the amadoue ; and Mr. Brossart, who first 

 brought this preparation into practice, conceives that that which grows on old 

 oaks, which have been lopped, is the most valuable ; that it should be gathered 

 in August or September, and be kept in a dry room. 



The way of preparing it, is to take off with a knife the white and hard part, 

 till you find a substance so soft, as to yield under the finger, like shammoy 

 leather. This is to be divided into pieces of different sizes and thickness : beat 

 these with a hammer, to give them a still greater degree of softness, so that they 

 may be easily torn with the finger. 



Mr. Morand thinks, that the agaric, which when growing is of a greyish 

 colour on the outside, is better than that which is white.* 



VJII. Of a Mountain of Iron Ore, at Taberg in Sweden. By Peter ^scanius, 



M. D. Translated from the Latin by Mr. Emanuel Mendes de Costa, F.R.S. 



p. 30. 



The mines of Sweden are justly esteemed superior to the mines of most other 

 countries; and those of iron are the most famed. Among the most curious of 

 the latter, is that of Taberg, if, with propriety, it can be called a mine. The 

 Swedish iron is, and has always been, carried to most parts of Europe, and is 

 preferred to all other iron. 



This mountain is situated in a sandy tract of land, of which the sand is ex- 

 tremely fine. The whole mountain is one mass of rich iron ore, and even in 

 some parts is mixed with particles of native iron. About 200 years ago (for so 

 long have they worked on this mountain) they blew up the masses of ore ; yet 

 the mountain appears very little diminished, except in the laves or hollow places, 

 which are at the foot of the mountain, opposite to the valley. In the interior 

 fissures of the mountain, bones of animals, as of stags and other kinds, are fre- 

 quently found imbedded in the sand. No ore is found beyond the foot of the 

 mountain, nor on the neighbouring plain ; so that it appears, as if the mountain 

 Jbad been artificially laid on the sand, for it has no roots, or, like other moun- 

 tains, its substance does not penetrate the ground. The ore breaks easily, and 

 what is broken from the sides of the mountain readily falls to the foot of it ; while
