48 THE BIOLOGY OF DAILY LIFE. 



smaller examples generally possess one nucleus 

 occupying the greater part of the corpuscle, the 

 larger ones usually include two, three, or even 

 more nuclei, and show more decided amoeboid 

 movement than the others. 



u Division by cleavage of the white cor- 

 puscles of the blood of the lower vertebrates 

 has been directly observed by Klein and 

 Ranvier."* (Klein's Histology, p. 13.) 



I now pass to the important subject of development, 

 again, like Polonius, promising " I will be faithful." 

 Let me just slide in one remark, the application of 

 which to the following quotation, also verbatim from 

 Klein's Histology, I leave to the intelligence of my 

 readers. Do not think I am trying to "make the 

 worse appear the better reason." I have not the skill, 

 even if I had the malice, of Milton's sophist, Belial. 

 (Par. Lost, bk. ii.) 



I know my remark has a suspicious appearance 

 of arguing that black is white. 



" All black birds are not blackbirds," otherwise a 

 sophist might prove that a crow was one of the most 

 musical of song birds. So let me say, 



All white corpuscles are not WHITE CORPUSCLES. 



I may also explain what is meant by development, 

 and some of the technical terms (such as mesoblast) in 

 the quotation which follows 



* My purpose, viz., that of showing how even generally 

 accepted teaching in Biology contains enough to prove all that 

 I contend for in food and medicine, is best served by quoting 

 from the newest and most reputed standard works, such as the 

 " Manuals for Students of Medicine," of which Klein's " Ele- 

 ments of Histology" is one.
