The animal, in whom artificial breathing was kept up, 

 mftead of having its heat maintained by the converfion of 

 arterial into venous blood, and vice i<erfd, was thus actually 

 cooled by the air conveyed into its cheft. 



Having thus afcertained, that the ordinary changes are 

 effected in the blood by its circulation and artificial refpira- 

 tion in a decapitated animal, Mr. Brodie proceeded to mew, 

 that the oxygen of the air undergoes its ufual converfion 

 into carbonic acid. He found, that a living rabbit formed 

 50 — 56 cubic inches of carbonic acid in an hour ; a de- 

 capitated animal, in whom artificial refpiration was kept up, 

 emitted 40—48 cubic inches in the fame time. The 

 thermometer in the rectum of the latter had fallen from 

 97 to 90, while in another rabbit left to itfelf, but fimilarly 

 treated in all other refpetts, it had fallen only to 91. In 

 a rabbit poifoned with woorara, or the efiential oil of 

 bitter almonds, not decapitated, and in which artificial 

 breathing was kept up, 51 cubic inches of carbonic acid 

 were emitted in an hour. The thermometer in the rectum 

 had funk to 91 in 30 minutes ; while it itood in another 

 animal treated exactly the fame, excepting the artificial 

 breathing, at 92. 



Thefe experiments fecm fully to warrant Mr. Brodie's 

 conclufion, " that in an animal in which the brain has 

 ceafed to exerc.fe its functions, although refpiration con- 

 tinues to be performed, and the circulation of the blood is 

 kept up to the natural (landard, although the ufual changes 

 in the fenfible qualities of the blood take place in the two 

 capillary fyftems, and the fame quantity of carbonic acid 

 is formed as under ordinary circumllanccs ; no heat is gene- 

 rated, and (in confequence of the cold air thrown into the 

 lungs) the animal cools more rapidly, than one which is 

 actually dead."

On the fubjett of this article, the molt valuable works, 

 both for the collection of facts from various fources, for 

 original views and refearches, acutenefs of investigation, 

 and clofe reafoning, are thofe of Mr. Ellis ; entitled, " An 

 Inquiry into the Changes induced on atmofpheric Air by 

 the Germination of Seeds, the Vegetation of Plants, and 

 the Refpiration of Animals," 1807. And, " Further In- 

 quiries, &c." 181 1. Dr. Boitock's " Effay on Relpira-

 known on this fubject up to that time. The preceding

RESPITE, Respectus, in Law, &c. a delay, for- 

 bearance, or prolongation of time, granted any one for the 

 payment of a debt or the like. 



Menage derives the word refpite from the Latin refpetlus ; 

 as defpite from defpedus. Du-Cange will rather have it come 

 from refpirare, to breathe ; refpite being, in effect, a breath- 

 ing-while, granted a debtor, &c. 



"In the cuilomary of Normandy, refpite is a judicial delay 

 or demur, given to procedures. 



RESPITE) Letters of, or Credit. See Letters. 



RESPITE of Homage, is a forbearance of the homage due 

 from the vaffal, or tenant, holding by homage, or by knight- 

 fervicc, to his lord. 



Anciently, thofe who held by thefe tenures paid a fmall 

 fnm every fifth year into the exchequer, to be refpited doing 

 their homage or fervice. 



By Hat. 12 Car. II. this refpite of homage is taken away, 

 as a charge arifing from knight-fervice ; which is thereby 

 likewife annulled.
