PARTRIDGE witn two HEARTS. 333 
each other exatly in fize, form and colour. From their 
thicker ends came out feveral veflels, among them I ob- 
ferved one to each of the bodies pretty large and paler 
than the reft; a part of this veffel was faftened to the 
lungs in fuch a manner, that by taking hold of only the 
Jungs, thefe two bodies in queftion were both fufpended at 
the fame diftance from the lungs. In placing thefe vifcera 
on the hand in fuch a manner that the refembling fides of 
thefe two bodies faced each other, the veflels which were 
fufpended appeared uniformly difpofed, which makes me 
imagine that the two bodies were uniformly difpofed in 
the body of the animal*. However, the above obfervati- - 
ons being frefh in my memory, I ordered the entrails of 
four dozen of partridges of the fame {pecies*, juft taken 
out, to be brought me; and I found in each a body like 
the double body which had been found in the bird of Mr. 
Vergé, having fimilar veffels, fome of which were paler ~ 
than others, adhering in the fame manner to the lungs, 
and this body was certainly a heart or my partridges had 
none. I neverthelefs leave every one at liberty to judge 
, Uu which 
Yautre, en volume, en forme, et en couleur; de leur gros bout fortoient plufieurs vaiffeaux, 
parmi lefquels j’en remarquai una chacun de ces corps, afséz gros et de couleur plus pale que 
Jes autres; ume partie de ces vaifleaux tenoient au poumon, de maniére que faififfant feule- 
ment le poumon, les deux corps dont il s’agit y reftoient fufpendus tous deux a la méme dif- 
tance du poumon. En arrangeant ces vifceres fur la main, de maniére que les cotes femblables 
de ces deux corps fe regardaffent, les vaifleaux quiy tenoient fe trouvoient fimetriquement 
difpofés; ce qui me fait juger que ces deux corps devoient fe trouver dans l’animal fimetrique- 
ment placés*. Enfin ayant encore la memoire fraiche des obfervations fufdites, je me fis ap- 
porter les entrailles de quatre douzaines de perdrix de la méme efpece+ que ]’on venoit de vi- 
der, et jai vii-qu’il fe tronvoit dans chacune un corps en tout femblable a celui qui s’etoit 
trouvé double dans la perdrix de M. Vergé, ayant de peareils vaiffeaux, dont un plus pale que 
les autres, tenant de la méme maniére au poumon, et ce corps etoit certainement un cceur, 
ou mes perdrix n’en avoient pas. Je laiffe maintenant chacun libre de juger lequel paroit le 
plus yraifemblable, qu’une perdrix eut deux ce@urs, ou qu’il ne s’en trouva pas un feul dans 
quarante 
* Fe prefume quils occupoient les deux: catés du thorax, et que les veines de Yun s'anaflomofrient aus 
art.res de Pautre ct reciproguement, 
(c) I prefume that they occupied the two fides of the thorax, and that the veins of the one 
anaftamofed with the arteries of the other, and vice verfa. 
+ Elle cft un peu plus petite que celle qu'on appelle en France perdrix de paffage ou raquctie, elle fe 
perche de meme. 
(d) It appears rather fmaller than that which, in France, is called perdrix de paffage, or 
raquette; they fit ona tree in the fame manner.
