Specimens of mountain-meal was brought by Mr Laing from the 

 parish of Degersfors, on the northern branch of the river Umea 

 in Umea-Lapmark. It was discovered in July 1832 by a farmer 

 in cutting down a tree. It forms a bed under moss, and has been 

 used by the natives, mixed with rye-flour, to form bread, and boiled 

 to make gruel. Government prohibited it on the idea of its being 

 unwholesome. 



Dr Traill found that it does not efi^ervesce with acids ; that it 

 loses by calcination 24 per cent, and becomes more white after first 

 blackening. The odour seems partly animal. The microscope 

 shews it to consist chiefly of bodies that have the form of elongated 

 and flattened elliptic bodies, probably the remains of infusoria. 

 Dr Traill is analyzing it, and considers it, from his preliminary 

 experiments, to consist chiefly of silica. 



In the same district, in bad years, the farmers make a bread of 

 half rye-flour and half bark. The inner bark of the pine is washed, 

 dried, and pounded, for this purpose. Specimens of this bread 

 were exhibited.
