An Account 
of an Experiment made by M}loo\ of Pr efer ving Animds dive 
hj Blowing through their Lungs mth Bellom^ 
This NMe Exferlment came not to the Publiilier's hands, till all the frece-^ 
ding Particulars were already fent to the Prefs^and almofl all Printed off, {for 
which caufe alfo it could not he mentioned among the Qontttitsi) And it might have 
been referved for the next offortmity^ had not the conjlderablenefs thereof been a 
motive to haflen its Publication. It fhall be here annexed in the Ingenious An* 
x^mthis o^n words, as he frefented it to r/?^ Royal Society , Odob. 24. ^66^, 
the Experiment it f elf having been both repeated {after a former fuccefsful trial of 
it^made by the fame hand a good while agoe) ^nd improved the week^ before^ ap 
f^^ir publick Affembly. The Relation it felffollowes 
I Did heretofore give this Illuflriom Society an account of an Experimeill 
I formerly tryed of keeping a Dog alive after his Thorax was all difplay'd 
by the cutting away of th^ Ribbs and Diaphragme and after the Pericardimn 
of the Heart alfo was taken off. But divers perfons feeming to doubt of the 
certainty of the Experiment (by reafon that fome Tryals of this matter,made 
by fome other hands, failed of fuccefs) 1 causM at the laft Meeting the fame 
Experiment to be fbewn in the prefence of this Noble Company^ and that with 
the fa me fuccefs, as it had been made by me at firft • the Dog being kept alive 
by the Reciprocal blowing up of his Lungs with Bellowes^ and they fuffered to 
fubfide, for the fpaceof an hour or more, after his 7"/;^?^^^? had been fodif» 
play'd, and \iis Afpera arteria cut off juft below the Epiglottis^ and;bound on , 
upon the nofe of the Bellows. 
And becaufefome Eminent Phyfitians had affirmed, that the Motion of the 
Lungs was necefl'ary to Life upon the account of promoting the Circulation of 
the Blood, and that it was conceiv*d, the Animal would immediately be fuffo- 
cated as foon as the Lungs fhould ceafe to be moved, I did (the better to for- 
tifie my own Hypothecs this matter, and to be the better able to judge of 
feveral others ) make the following additional Experiment ^ vi^o . 
The Dog having been kept alive, (as I have now mentioned) for above an 
houre, in which time the Tryal had been often repeated, in fuffering the Dog 
to fall into Convulfive motions by ceafing to blow the Bellows, and permitting 
the Lungs to fubfide andlyeftiil, and of fuddenly reviving him again byre- 
newi ng the blaft, and confequently the motion of the Lungs : This, I f ^y, ha- 
ving beendone^ and the Judicious Speftators fully fatisfied of the reallity of the 
former Experiment- I caufed anoiher pair of Bellowes to be immediately 
joynM to the firft, by a contrivance, I had preparM,and pricking all the outer- 
C0.it ofche Lungs with the flender point of a very (harp pea-knife,, this- fecond
