W. M. Carpenter on the Muscles in the Glass Snake. 93 
Now each of the fascicles of this series being met at each of 
its extremities on alternate sides, by other fascicles at acute an- 
gles, unite with them to form the hollow little cones already 
mentioned. Each of these cones is received and exactly fits in- 
to the hollow of that which stands next to it in the direction of 
its point ; and in turn it receives the point and body of that which 
stands next to it in the direction of its base. Each of these cones 
may perhaps be one third or one fourth as long as the entire fas- 
cicles of which it is composed. 
Some of the fascicles being attached near their middle to the 
bones, have both of their extremities free, and it is by these free 
extremities that the conical muscles, in each direction, are form- 
ed; while those fascicles which have their attachment to the spi- 
nous and transverse processes, are attached by their posterior ex- 
tremities, and from them project only forwards, and having only 
one free extremity, enter into the formation of only one set of 
muscles. 'The points of attachment which are in the middle of 
some of the fascicles, are common to both the anterior and pos- 
terior sets of muscles. The fascicles surrounding a bone have 
each a single point of attachment to that bone, and are not at all 
attached to any other bone ; and the series of amuanles surround- 
ing a bone, has. fibrous or aumeralen attachments to this bone 
alone, and has no fibrous attachments to any other tissues, except- 
ing a very slight one on its contour, to a thin fascia which sur- 
rounds the series and binds it together.

Iasi 4, [have endeavored to show the arrangement of the 
fibres in each of the fascicles, which, in the middle portion, is a 
flattish muscular membrane, and for a portion of its length to- 
wards each extremity, forms the lateral half, A and A’, of a hol- 
low muscular cone, the concavity, in the two, presenting in oppo- 
Site directions, and which meeting with other similarly arranged 
fascicles, completes the cones which stand in opposite directions, 
The foscicle j is attached to the bone by the middle at B. 
In fig. 5, I have endeavored to exhibit the manner in which 
the systems of muscular cones, connected with two contiguous 
bones, mutually receive and are received by each other. The
