Now

the parts are obvious enough to physical perception. However,
with the view of observing due order and sequence and of combining
rational notions with physical perception, we shall proceed to
enumerate the parts: firstly, the organic, and afterwards the simple
or non-composite.
The chief parts into which the body as a whole is subdivided,
are the head, the neck, the trunk (extending from the neck to the
privy parts), which is called the thorax, two arms and two legs.
