48 THE EVOLUTION OF LIVING BEINGS. 



casian army, the Mongolian army, the Indian army 

 and the Negro-Army. 



Suppose now, on the contrary, that the bataillons 

 we originally made, had been of the proper size, then 

 uniting them to regiments, would already cause a 

 change of constitution, because we would get, say a 

 Caucasian-Mongolian and an Indian-Negro regiment, 

 in stead of specifically pure regiments, so that the 

 army, consisting of such regiments, would have to be 

 designated as the Caucasian-Mongolian-Indian-Negro- 

 Army. We could of course also constitute a Caucasian- 

 Mongolian-Indian-Negro army by dividing, from the 

 beginning, all four species equally over each bataillon. 



Now if we compare these different kinds of armies, 

 we find that each of the armies of the first kind con- 

 sists of one species only, that in the army of the se- 

 cond kind the bataillons constitute species, but the 

 regiments Linneons, and that in the army of the 

 third kind the bataillons already are Linneons, con- 

 taining different species, be it, each species consisting 

 of but a small number of individuals. 



Now what does Nature say to such grouping ? 



Suppose we try to find out. To do this, we discharge, 

 the men and women, marking each of them by a ta- 

 too-mark indicating the bataillon to which he or she 

 belongs, and charge them to mark their progeny to 

 come, with the same tatoo-marks they got themselves, 

 each child thus obtaining two tatoo-marks, one from 

 his father and one from his mother. 



Now suppose twenty-five years later, we enlist these 

 children and arrange them in our armies according to
