sustains all the physical sciences, namely, induction, meneenaes the 
correspondence of the phenomena with the theory. 
Those who have not profoundly studied the science, cannot 
judge of the details; it certainly appears very extraordinary that 
numerous organs should be included within a mass no larger than 
the brain, and that so many faculties should be found in particu- 
lar regions, especially in that of observation along the front and 
lower portion of the brain, contiguous to the eyes and the arches 
of their orbits. It appears the more strange, inasmuch as dissec- 
tion does not enable us perfectly to separate the different organs, 
although the convolutions of the brain are distinct, and may in- 
deed be dissected apart; but there are no visible boundaries be- 
tween the organs, so that they can be removed, one by one, 
There is however an apparatus by which communication is made 
to them and through them by the medium of nervous fibres ; 
many groups of these fibres are visible in the brain, pervading 
different organs, and therefore we may presume that, where we 
cannot see them they may still exist, and perform their office of 
communicating their appropriate impressions. 
Strong analogies favor this view. For example, in addition to 
the nerves and blood vessels that may be traced in every part of 
the body, there are certainly others that exist in inconceivable 
numbers and with an infinitesimal minuteness, baflling equally 
our powers of vision and dissection, and even of conception; for, 
whatever part of the system we puncture with a needle or other 
sharp instrument, we both draw blood and excite pain, thus prov- 
ing that not only blood vessels but nerves of vanishing minute- 
ness pervade the entire structure, and every one of these blood 
vessels receives its stores of blood from the circulation that is sus- 
tained by the contractions of the heart, faithfully returning the 
vital fluid again to that organ; in the same manner, the infinitely 
divided nervous fibres all communicate ultimately with the brain, 
and thus when they are wounded, impart the information from 
the remotest extremities to the grand head quarters of the mind, 
and that quicker than an electric movement in our machines, or 
- in the atmosphere, or in the wide external world. 
But this is not the ultimate term of infinitesimal minuteness. 
While every part of the system is thus furnished with nerves of 
common sensation, so that we suffer by a wound inflicted in any 
place; and the mind is instantly informed of the injury ; there
