Jfiflux of the Animal Spirits into the Nerves that were fc- 
parated in the Brain, I carried the Subjeft to MonficurDa 
Ferny ^tokdoT of Anatomy in theRoy alGarden ^iParu^to 
have it more carefully examined^ v*ho willingly complied 
with my defire : And firft he (earch.d for the Oprick 
Nerves,but they being ruined by theabove-mentionedPer- 
fonSjhe could not faywhetherthey had been there or not. 
2. He traced the eighth and ninth pairs of Nerves and 
IntercoftaJ. 3. Having cut i:p the Canal of the Verte- 
bres, difcovered the Medulla Spinalu all along the Ca- 
vity, and traced all the vertebral Nerves proceeding 
therefrom ; as a!fo the fciatick Nerve confiderable e- 
notigh : It is true, the Medttlla Spinalis was not here of 
that confiftence as in adult Perfons ; but one could with 
feme pains obferve all the four Tunicks, and the two 
Subftances as in the Brain, to wit, the Cortical or Glan- 
dulous Subftance, and the Fibrous or White, but with 
this difference, that the Brown Subftance is exterior in 
the Brain^. but interior in the Medulla Spinalis^ for it is 
, as it were a third Brain contained in the Canal of the 
Vertebres fb framed for its defence ; for there are Me- 
ninges as in the Brain, Sin's and Cavities which may 
pafs for Ventricles : In a word, one can fay all of U 
that they can of the Brain, and more, for it appears 
more fenfible and necelTary for the Life, for you can 
take the Brain or Cerebellum from an Animal, and yet 
the Animal (hall live fometime thereafter ; but a Wound 
or ComprefTion of the Medulla Spinalis will caufe fudden 
Death. And the Generation, or Filtration, and Diftri- 
bution af^ Animal Spirits, is performed the fame way 
as in the Brain: And Monfieur Du Ferny has obferved, 
that all the Subjeds of this nature, that he has had oc- 
cafion to diflecS:, never one of them was found wanting
