Oil, A TREATISE ON PILE. 73 



NOTE TO TABLES B, Nos. 1, 2, 3 AND 4. All the terms used in these tables, which were 

 previously used in Tables A, have the meaning already explained. 



h h 



The word "hypo" (from upo, under,) and hyper (from uper, above,) are necessarily 

 introduced into these tables, as they are based upon a division into 10 parts of blood ; 

 these words bringing 8 parts into 16th. 



The whole nomenclature has been founded upon a division of eight, because it is not 

 often desirable, or even practicable, to carry the division further. 



Examples. " Tetra-di-costin." The te.tr a means | or T ^ ; the di means f or T %, making 

 together, if, the complement of which is, necessarily, j* ff , which, therefore, need not be 

 expressed. 



Now, as "costin" means black and Indian, (not Indian and black,) the "di," (i. e., the 

 | or T 4 6 -,) must refer to the black portions; the term "tetra," (i. e., the f or T \,) refers 1o 

 the race mixed with the costin, and as this is black x Indian, the "tetra-di-costin" is a 

 triple race in the proportions of 8 X4 X 4; i, e., 8 white, 4 black and 4 Indian 



NOTE TO TABLE G. All the terms used in this table have already been explained, and 

 are used in the same senses. 



There is an advantage obtained by making each species primary in its turn, as is done in 

 all these tables; for example, take the name "hexa-hypo mono," which is a mixture of 

 three species in the proportion of 12X1x3, counting in 8fhs ; the if reads "hexa," the -Jg-, 

 (being made from f or "mono,") preceded by "hypo," indicating that it is less than |, 

 that is to say, ^, and the whole making " hexa-hypo-mono-costin." But if the order was 

 from white to black, and also, from white to Indian, the third number would have to be 

 indicated ; and then, instead of the word " hexa-hypo-mono," now used, it would be 

 necessary to write " hexa-hypo-mono-hypo-mono," which would be unwieldy. 



It is believed that the tables, as now presented, indicate all the shades in a distinct 

 manner ; and although some of the names may, at the first view, appear to be long, it is 

 submitted that the same complicated idea cannot be expressed in any shorter manner. 



THE COVERING OF THE HEADS OF HYBRIDS. The pile of the head of human hybrids 

 does not exhibit one uniform new variety, varying from that of both parents ; but gene- 

 rally, perfect filaments which resemble that of the one parent, and other perfect filaments 

 which resemble that of the other parent ; for example, the progeny of a white and a black 

 will have some perfect oval hairs, and some perfect eccentrically elliptical wool ; so the 

 progeny of a white and an Indian will have some perfect oval hairs and some perfect, 

 cylindrical hairs, and the progeny of an Indian and a black will have some perfect cylin- 

 drical hair, and some perfect eccentrically elliptical wool ; and, even further, one who has 

 in his veins the blood of all these species will generally have in his head pile belonging to 

 all three. Sometimes, however, where the constitutional energy of one parent outweighs 

 that of the other, only one species of pile will be found.
