both are moving. But the fact that these con- 

 ditions exist, and must be satisfied, is not the 

 ultimate fact, it is not even the main fat which 

 Science apprehends in such phenomena as these. 

 That which is most observable and most certain, 

 is the manner in which these conditions are 

 met. But this, in other words, is simply the 

 subordination of many laws to a difficult and 

 curious Purpose ; a Purpose none the less 

 obvious, and a subordination not the less re- 

 markable, because effected through the instru- 

 mentality of mechanical contrivance. 



" The new-born Kangaroo," says Professor Owen, " is 

 an inch in length, naked, blind, with very rudimental limbs 

 and tail : in one which I examined the morning after the 

 birth, I could discern no act of sucking : it hung, like a 

 germ, from the end of the long nipple, and seemed unable 

 to draw sustenance therefrom by its own efforts. The 

 mother accordingly is provided with a peculiar adapta- 

 tion of a muscle (cremaster) to the mammary gland, by 

 which she can inject the milk from the nipple into the 

 mouth of the pendulous embryo. Were the larynx of the 

 little creature like that of the parent, the milk might, 

 probably would, enter the windpipe and cause suffocation : 

 but the fcetal larynx is cone-shaped, with the opening at 

 the apex, which projects, as in the whale-tribe, into the 

 back aperture of the nostrils, where it is closely embraced 

 by the muscles of the ' soft palate. The air-passage is 

 thus completely separated from the fauces, and the in- 

 jected milk passes in a divided stream, on either side the 

 base of the larynx, into the oesophagus. These correlated
