REMARKS ON THE FIGURES OF PLATE XXII. 
‘THE CERVICAL AND LUMBAR REGIONS OF THE MAMMALIAN SPINAL AXIS ARE INCONSTANT AS TO THE 
NUMBER OF THOSE FORMS OR QUANTITIES USUALLY NAMED VERTEBRA, 
IATUS, gap, deficiency, or vacuity, is caused in plus serial quantities, by the subtraction or metamor- 
phosis of elementary parts proper to the uniform archetypes. Those archetypes or serial plus 
figures persisting in full structure from first to last, throughout that line which they describe, give example 
of a plus uniform creation uninterrupted in its whole extent, and may be symbolised thus—9, 9, 9,9,9, 9, 9,9. 
But when fitness requires that this uniform series should undergo modification in some region or regions of 
its extent, then the purpose is effected by a subtraction of quantity from one or more of those serial units, 
and this causes hiatus or void, which is tantamount to species, which is a mode of increation, and bears 
to be symbolised thus—9, 8, 8, 8, 8, 8,8,95; or, according to the degree of subtraction, will specifically vary 
from ‘the plus sum of original series, and yield the figure in many graduated conditions of development, as, 
for example, 9, 7,7, 7,7, 7, 7,9, or 9, 6, 6,6, 6,6,6,9, or 9,5, 5,5, 5,5,5,9. Subtraction of quantity taking 
place upon the same units of the original series of the quantities 9 will at length reduce them to this state, 
9,1,1,1,1,1,1,9. But. yet it will appear that this latter state of series will refer itself to the original plus 
condition, and so, between the contrast or comparison of series as it is, and of series as it once was, we read 
the paces of the law of form. The extremes of the metamorphosed series, 9, 1, 1,1, 1,1, 1, 9, while still 
remaining in plus condition, indicate the degree of subtraction which has taken place upon the quantities of 
the original means, or intervening quantities, and thus the integer 9 lends interpretation to the fractional 1, 
by telling that that 1 occurs in series, by the subtraction from 9, for 9—8=1. The cervical and lumbar 
regions of the mammalian axis are the effects of the act hiation, which subtracts quantity from the original 
series of costo-vertebral archetypes or integers, after the same manner as above specified. 
That series of proportional quantities which holds with- Fig. A represents the human cervical region of spinal 
in itself at some one region or other the archetype form 
to which all such proportionals can be referred, may be 
numbered from end to end as though it were a series of 
archetype quantities. For we understand the proportional 
only inasmuch as we know it to be the proportional of some 
full quantity or archetype. Therefore as the part speaks of 
the whole from which it has been metamorphosed, so when 
a vertebra as part of the thoracic quantity or whole stands 
in serial order with this archetype, we then may number 
the minus vertebra as though it were a plus thoracic 
quantity, sce we know it to have come of such quantity. 
The archetype quantities are uniform, and the vertebree 
are the proportionals of such as these. Since a+b=c, 
then c—d=a; or in other words, since the vertebra 
plus the costz equals the costo-vertebral archetype, then 
this archetype minus the costee equals the vertebra. 
series, and we number the serial quantities from the atlas 
above to the seventh vertebra, after which the thoracic 
quantities ordinarily commence. The seventh unit of series 
is marked 7, and in it we see the autogenous piece a. This 
seventh unit is immediately succeeded by the first thoracic 
quantity marked 1d, and from it we see projecting the 
costa a to meet its fellow of the opposite side at the sternal 
median line in front. It is evident that this costo-vertebral 
quantity contains within itself a proportional similar and 
equal to the vertebra marked 7 a; and therefore it is that 
we interpret the form 7 a, to be a proportional of sucha form 
as lda. With this interpretation then, we become pre- 
pared for all the plus anomalies of the minus quantity 7 a. 
Fig. B proves the correctness of the above interpre- 
tation, for we actually find that the seventh cervical unit 
has produced its autogenous elements a, to the character
