REPORT OF CHEMISTRY, NATURAL PHILOSOPHY, &c. 



MM-AJENDii;, in his recent Elements of Physiology, considers all those bodies, the 

 , composition of which is constant, as iwrf^anie ; and those, the elements of which 

 arecontiuuaiiy v.irying, as living, or organic. They differ from each other in their form, 

 composition, and the laws which regulate them. Inorganic bodies are submitted en- 

 tirely to the ';i\v" of chemical affinity and attraction; living bodies are governed partly 

 by tlicsc Irtws and partly by an imkuown agent or power. Two classes of living bo- 

 dies, vegetables and animals, he has thus contracted : 



Vegetables — are fixed to the earth, I Animals — are moveable on the sur- 

 bave carbon for the chief ba-is of their | face of the earth, are often composed of 



eight or ten cl< ments, with azote for 

 their principal base, have no need to act 

 on their food to render it proper to nou- 

 rish them. 



From a number of facts, M. Methuon conceives " that the natural pvoce.ss of crys* ' 

 tallizntion originally begins in a partial decomposition of the surface of a crystaUizahle 

 fossil ; that from rcrfain spots of tliis surface, where it has first begun, the decomposition 

 proceeds in straight and narrow lines to other similar spots, which in their turn send forth 

 similar lijjes, sometimes paiallel to the formerj at other times crossing each other ; thus 

 dividing, or, more commonly speaking, carving orengraving the suifaccofthc fossil into 

 several compartments, which becimie, by a continuance of the process of decomposi- 

 tion, as many distinct pieces, constituting the body of the crystal in its rough state ; and 

 lastly, that duiiug this pioccss the substances of a difierent nature, contained in the mi- 

 neral, separate, and arrange themselves, in one or more parts of the same compartment, 

 the fossil mass continuiuL' to be solid and hard, but fragile and easy to be broken ;" the 

 author, havini; often broken, between his fingers, some which had before withstood the 

 strongest percussions. 



RI. Methuon maintains- that he has proved : " 1st, That crystals begin to form at their 

 summit, edges, and solid an;; les. 2dly, That nature produces, by a direct process, all 

 simple and compound crj stals, without first forming a vvckvs in the latter. .Sdly, That 

 lUe mutter, serving to form the crystals, is in the state of a solid mass before, and con-
