work of a great and worthy naan lately oeceafed, an 
ejfay on the vital and involuntary motions oj animals . ? 
by Dr. Whytt *. 
' And it deferves to be remarked, that parts, whofe 
motions are of this mixed kind, will be found to have 
generally a double diftribution of nerves, namely fuch 
as are without ganglions, to fubjeCt them to the will ; 
and fuch as have ganglions occafionally to iupport 
thofe motions of the fame parts which go on without 
the will ; but, thefe lupplies from the interco/tals 
being very minute, their adtion is generally called 
forth and aflifted by fome degree of uneafy fenfation 
or flimulus. 
If thefe anatomical objections have not force enough 
to overthrow our dodtrine, the following of a phyfio- 
logical nature, it is prefumed, will not be more formi- 
dable. 
3. It has been objected, that if -the ganglia inter- 
cept the communication between the fenforium com- 
viune and thofe parts whofe nerves are derived from 
them, they ought not only to intercept the commands 
of the will, and render the motion of thefe parts not 
voluntary, but they ought alfo to prevent the im- 
preflions made on the nerves of thefe parts from being 
conveyed to the fenforium commune , 1. e. thefe parts 
ought to be infenfible.. The contrary of which is 
true , for example, the inteftines, whofe nerves come 
from ganglia , are among the moft fenfible parts of 
the body. And if the uneafy fenfation in the lungs, 
in aflhmatic cafes, was not conveyed to the fenforiuin 
commune , how could the will redouble the action of 
£he diaphragm and the intevcojlal mufcle.s ?
