LIFE AND OKGANISATION. 89 



duce the perfect form in each of the divided parts. In some 

 of the Infusoria, the problem is further perplexed by a double 

 manner of generation through ova, and by self-division of the 

 animalcules themselves. 



All these things, and others equally wonderful such as 

 the modes of parasitic or complemental generation described 

 by Mr. Darwin in his Monograph on Barnacles may well 

 astonish those who come unprepared to the subject. In 

 reality, however, there is nothing more unintelligible here 

 than in the familiar facts of ordinary generation, nor more 

 wonderful than what we before knew as to the economy of 

 other animals higher in the scale of creation. The modes of 

 reproduction of the Bee (especially as last developed by the 

 researches of Dzierzon and Van Siebold) may be taken as an 

 epitome of all that is most marvellous in this great function 

 of life. The true mystery, as we have already said, lies 

 deeper; and is equally associated with every variety and 

 aspect of these phenomena. It is one of the many cases in 

 science and philosophy where familiarity gives a semblance 

 of knowledge ; satisfying the shallow enquirer, but otherwise 

 estimated by the more cautious seeker after truth. The 

 several questions we have been discussing, and others not 

 less difficult of solution, are all subordinate to the single 

 problem of the transmission of life and likeness from one 

 living being to another. All theories and systems are alike 

 arrested at this point. The problem, in truth, is one insoluble 

 by the present capacities of man. 



Another topic of eminent importance to all our views of 

 life, and the economy of living beings, is that of Animal 

 Instincts. Much has been observed, thought, and written 

 on this subject; but less connectedly, we think, than its 

 interest requires. Facts have been multiplied and better de- 

 fined ; and the. special structures serving to the fulfillment 

 of instincts more carefully, yet for the most part vainly
