find its parts examined by a celebrated phyfician of his 
time, Velchfius, from whom Blafius has taken it, 
and by the Academy of Sciences. Blafius has, how- 
ever, made the anatomical diftribution of its parts and 
their explanation ; from whom I fhall take the figure 
inafomewhat larger fcale, for its better illuftration ; 
and although this laft author quotes Severinus and 
Coiterusas difledors of the tortoife, as well as Velch- 
fius, yet this latter only mentions the wind-pipe. 
In Blafius’s figure, this pipe, for a few inches from 
the epiglottis, is Angle, but foon divides into two ; and 
as it defcends in company with the oefophagus, it 
forms a folded ring outwards on each fide, and turns 
down again to enter the lungs : fo that the animal has 
the advantage of a double afpera arteria, with a 
volution in each : which fhews that this provilion is 
intended to contain a greater portion of air than or- 
dinary while he is under ground in winter.. 
The tortoife difieded by the Academy of Sciences, 
was a large land tortoife from the coaft of Coromandel ; 
in which was found a biffid wind-pipej each branch is 
faid to be fix inches long, but no mention is made of 
the volutions in this land tortoife ; which, one would 
think, being fo remarkable a variety from the common 
ftandard, ought not to efcape the notice of fu'ch able, 
anatomifts. Yet it was found, by feveral experiments, 
that refpiration was very flow and unequal in this 
animal, as well as in the camelion ; the Academicians 
obferved feveral tortoifes for a long time together, and, 
have taken notice, that they fometimes call; forth a cold 
breath through the noflrils, but that is by long inter- 
vals and without order ; and that the camelion is
