Here may in, very appropriately, some sugges-
tons of Professor Draper himself given in an introduc
tory lecture Phosphorus before his Medical Glass, in
October, lS47:
No intellectual operation take place except be
attended by the oxydaton of phosphorus and accord
as II is more vigorous and prolonged is the amount OF
that oxydation greater The who breathes por OF
ether and thus partially prevents the naturalization of
his blood, necessarily puts check on ai5 chemical
change and for the time being he TO have clear
perception OF things he becomes nsenble to the most
terrible operations of surgery On the other hand the
nan who breahes the protoxide of nitrogen erare
rallies hrs blood. In the interior Of his system all
oxydzing processes 60 at accelerated rate fever

pass oeiore him; he lives year IN minute and that
year s IN the seventh heavens Do not misappre-
bend what say would not have you suppose that in
tellectua operations in material changes The fact
am pointing out is, that in the action of the mind on
external things chemical changes intervene We all know
that mental operation directly any mechani

may be, lift from the ground" Nor the

organs that the mind there is lever-ke arrange
ment OF bones, which is set in action by the contrace
power Of the muscles, and these in their by the
nerves. In this chain of physical events intervening
after the primitive action of the mind the oxydaon OF
phosphorus bears essential part Your anatomical
studes Will teach the character OF these
organs They will for instance, set forth the parts OF
eye its coats its humors its lens, and how the
expansion of the retna is connected with the train

images Of external objects form, optical principles,

that though certain the action OF that nerve
special yet in reality is like that of any other sensory
nerve which in like transmits the impression OF

am material to take step in advance of the idea
presented above and maintain that intellectual operations
do arise in material changes The lecturer himself takes
this STEP perhaps unwtngly For example, the rays Of
light reflected from fall upon his retna; its nerve
