 drous succession of phenomena which the life-history of every 

 individual among them exhibits, and to the order and constancy 

 which this presents. Still more is this the case, when we direct 

 our scrutiny to the penetration of that universe which may be 

 said to be included in the body of Man, or of any one of the 

 higher forms of organized being, and survey the innumerable 

 assemblage of elementary parts, each having its own independent 

 life, yet each working in perfect harmony with the rest, for the 

 completion of the wondrous aggregate which the life of the whole 

 presents. In the study of the one*class of phenomena, no less 

 than in the survey of the other, we are led towards that Infinity, 

 in comparison with which the greatest and the least among the 

 objects of Man's regard are equally insignificant ; and in that 

 Infinity alone can we seek for a Wisdom to design, or a Power 

 to execute, results so vast and so varied, by the orderly co-opera- 

 tion of the most simple means.
