can still be seen in various stages of develop- 

 ment moving about in the parent cell, and as 

 one leaves, another very minute nucleus will 

 be seen just coming into view : thus favouring 

 the presumption that this multiplying process 

 may go on under congenial conditions ad 

 infinitum. . . . 



"The white corpuscle is to be seen of every 

 size, from the germ just left the parent to the 

 full-grown cell, exceptional ones of which I 

 have seen containing as many as thirty-five 

 germ corpuscles, or nuclei."* (Physianihropliy, 

 p. 125.)

THE WONDERFUL METAMORPHOSIS REQUIRED BEFORE A 

 LEUCOCYTE COULD CHANGE INTO A RED CORPUSCLE, 

 LONG LOOKED OUT FOR BY HOSTS OF MICROSCOPIC 

 OBSERVERS, GENERALLY ASSUMED BY PROFESSORS OF 

 PHYSIOLOGY, &C., BUT NEVER ONCE SEEN, OR ANY 

 STAGE OF IT. 



" Amongst the hosts of microscopists not 

 one so far (although their minds have been 

 driven into this groove), has observed a tran- 

 sitory phase of change of that wonderful meta- 

 morphosis which must of necessity take place 

 before the ' white corpuscle' can be changed 

 into the red. 



" For it must first cast off its cell-wall, lessen 

 its size, alter its configuration, internal organisa- 

 tion, and specific gravity. It must change its
