An Account 
Of an Experiment made by ,Hook 5 of Preferring Animals alive 
by Blowing through their Lungs with Bellows. 
T his Noble Experiment came not to the Publisher's hands, till all the prece - 
Ami Particulars were already font- to the P refs, and almofi all Printed of, (for 
which caufe alfo it could not be mentioned among the Contents :)And it might have 
been ref crved for the next opportunity , had not the confiderablenefs thereof been a 
motive to hafien its Publication. It fhall be here annexed in the Ingenious Au- 
thor his o\\m words, as he prefented it to the Royal Society , Q$ft©b. ?4‘ iri^7* 
the Experiment it felf having been both repeated (after a former fuccefsful trial of 
ft, made by the fame hand a good while agoe) and improved the wee f before, at 
their publlck Affembly. The Relation it felffollowcs 
f Did heretofore give this Llluflrious Society an account of an Experiment 
I formerly tryed of keeping a Dog alive after his Thorax was all difplay’d 
by the cutting away of the Kibbs and JDiaphragme •, and after the Pericardium ■’ 
of the Heart alfo was taken off. But divers perfons Teeming 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 caus’d at the laft Meeting the Time 
Experiment to be Shewn in the prefence of this Noble Company , and that with 
the fame fuccefs, as it had been made by me at firft • the Dog^being kept alive 
by the Reciprocal blowing up of bis Lungs with Bellowes , and they fuffered to 
fubfide, for the fp.ice of an hour or more, after his Thorax had been fo dis- 
play'd, and his Afpera arteria cut off juft below the Epiglottis , and bound on 
upon the nofe of the Bellows. 
And becaufefome Eminent Phyfitians had affirm’d, 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 loon as the Lungs Should ceafe to be moved, I did (the better to for- 
tifie my own Hypothecs of this matter, and to be the better able to. judge of 
feveral others ) make the following additional Experiment ^ viz, . 
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 int osConvulfive motions by ceafing to blow the Bellows, and permitting 
the Lungs toftibfide andlyeftill, and of fuddenly reviving him again byre- 
newi ng the blaft, and'confequently the motion of the Lungs : This, I fay, ha- 
ving been done, and the Judicious Spe&ators fully fatiefied of the reallity of the 
former Experiment-, I caufed another pair of Bellowes to be immediately 
joyn’d to the firft, by a contrivance, I had prepar’d, and pricking all the outer-
