REPRODUCTIVE SYSTEM. 
‘Tae organs which we have hitherto been considering, 
refer exclusively to the individual, and are necessary te 
the support of the system throughout the whole of life; 
those which now claim our attention, do not refer to the 
wants of the individual, but are subservient to the contmua- 
tion of the species. The ‘instincts by which the organs of 
reproduction are governed, have been already enumerated, 
when treating of the active powers of the mind. At pre- 
sent, it only remains for us to enquire into the different 
modes by which animals are propagated, and -the various 
organs which are called into exercise in each. 
The simplest mode of generation does not require sexual 
organs for the accomplishment of its purpose. Part of an 
individual drops off, and speedily exercises the functions of 
an independent being. This is termed Generation by Spon- 
taneous ‘Division. In other cases, a bud is produced from 
the surface, which gradually evolves, drops off from the 
parent when ripe, and ‘begins to exhibit a separate life. 
This is termed Gemmiparous Generation. 
In those animals which possess peculiar organs for the 
preparation of the germ or ovum, some are Androgynous*, 
and either have the sexual organs incorporated, and capa- 
ble of generating without assistance, or the sexual organs 
are distinct, and the union of two individuals is necessary
