234 On the Erratic Phenomena of Scandinama. 



offensive smell. The other portion of a fawn-colour, about the 

 size and form of a barley-corn, was enveloped in a membrane, 

 (perhaps a pellicle of mucus) and was surrounded by a fluid, 

 transparent and of a light brown hue. The solid matter 

 proved to be chiefly lithic acid ; the liquid seemed to contain 

 a matter like urea in solution ; but the quantity was too mi- 

 nute to allow of its nature being determined with any accu- 

 racy. It emitted an odour like that which urea gives when 

 acted on by nitric acid ; and, heated, yielded a little yellow 

 residue.

In a memoir presented to the Academy of Sciences, in the 

 beginning of 1843, I compared the erratic phenomena of the 

 Alps and the Pyrenees with those of the north of Europe, and 

 I pointed out some of the relations which exist between 

 them. Several naturalists have endeavoured to apply to the 

 erratic phenomenon of the north a theory which has lately 

 made a great noise, and have imagined the existence of im- 

 mense glaciers, or of vast sheets of ice, which, according to 

 them, formerly covered the whole north of Europe. In the 

 memoir just cited, I endeavoured to shew the impossibility of 

 that hypothesis ; and, to the facts already adduced, I have 

 now to add some others, which seem to me incompatible with 

 the glacial theory.
