transverse apophyses—D and D’ are the oblique articulating - 
physes. 
These bones are but slightly attached to each other by Lise 
ments. There are rudiments of capsular ligaments, which are 
very thin fibrous membranes surrounding the articulation ; and 
there are a few fibrous filaments passing from one of the spi- 
nous apophyses to the other ; but they are all so delicate that they 
would be > inadequate to hold the ~~ —. 
In the diagram, fig. 3 
have attempted to tn 
the relative situation and 
direction of the muscular 
fascicles which enter into 
the composition of the * 
muscles, situated around 
two contiguous vertebral eines 
bones. Supposethelayer :

ning at the dorsal median line. Let the 1 line A A’ represent the di- 
rection of this line, in which the points of the superior spinous pro- 
cesses are represented by the points A and A’. Starting from the 
spinous apophyses A and A’, the first fascicle on each side of the 
median line, runs obliquely forward and downward, and may be 
represented by the lines Ad and A/b’, and are met at their anterior 
extremity by fascicles 16 and 1/6’; running with equal obliquity, 
forward and upward. The fascicles 61 and 6’1’ are met at their 
other extremities by fascicles cl and e¢/1’; and so on with the 
other fascicles which are thus connected, and may be followed 
on around until we get back to the starting points at the spinous 
apophyses, on the side opposite to that on which we commenct 
following this zigzag and continuous series. These fascicles 
have attachments near their middle to the bones, with the excep- 
tions of those which are attached to the spinous and transverse 
apophyses, which have their attachments by one of their extrem- 
ities. Thus in the diagram fig. 3, the points A A’, BB’, CC’, 
represent respectively the superior spinous, the inferior spinous, 
and a seepeyese, and it twill be seen that the fascicles
