126 REVERSION, NOT A LAW, SUI GENERIS. 



complexity of the crystal, and controlled the whole 

 formative process, for that crystal. It is equally mani- 

 fest, that, when the integration, of the crystal, is once 

 fully attained, there is a peculiar play, and correlation, 

 of the forces of the crystal, which constitute a coordi- 

 native power, invested with the capacity, to keep all of 

 the parts together, and capable of repairing any part, 

 when lost or injured. 



It may be well to state, that the organic species, is 

 not the analogue of what is termed a species, in 

 crystals; but, it is the analogue of those forms, 

 which are absolutely alike, when they are not in- 

 jured, or truncated. Thus, the flowers of snow, in 

 crystallographic parlance, are termed a species. These, 

 however, do not correspond to an organic species, but, 

 rather, to an organic genus ; it is those of the flowers 

 of snow, which are precisely identical, in shape and 

 form, cleavage, &c, which are analogous to a species 

 of animal or of plant. 



These different flowers of snow did not evolve, from 

 one another, but they commenced, and completed, 

 their integration, independently of the others. No 

 similarity can, with them, afford an argument in favor 

 of their evolution, one from another. So, with species 

 of animals and plants. They were evolved, specially, 

 each from an independent centre. Neither, the simi- 

 larity of different species, nor their natural subor- 

 dination, group under group, justly implies that 

 they evolved, one from another. Kinship is not 

 necessarily the bond, between the individuals of the 

 same species. The only necessary tie between them,
