protruded from the mouth of the Dromedary, 1S9 
travellerSj who incline to distinguish three species of camels; 
viz. 15^5 The Bactrian Camel ^ with two humps ; ^d^ The Dro^ 
medary^ with a single hump, a small head, slender legs and 
neck, a light body, and gifted with great fleetness ; The 
common or Arabian Camel, also with a single hump, with 
stronger limbs, a thicker neck and body, and a slower pace ; 
and to this species he would refer the Tuscan camel. Yet, it 
may be asked, are the distinctive marks between the common 
camel and the dromedary sufficient to constitute a species ? 
Certainly not. No naturalist will attach to them so much con- 
sequence as to make them the diagnostics of a permanent va- 
riety, or a species ; and Forskall himself considers the animals 
simple varieties of the same species, remarking that the drome- 
dary, a camelo ( mdgari) non specie sed propagatione differt^ 
—Forskall, Animalmm Descriptiones, kc. quse in Itinere Orien- 
tali observavit. Havni«, 1675, p. 4. Our camel, then, I place 
in the species Di^omedarius^ although I admit that the specific 
name may not be very suitable, because the name dromedary is 
thus not appropriated to a species distinguished for fleetness, 
but used generally to denote all camels with a single hump. 
Yet, as Linnaeus, Buffon, Cuvier, and all the most approved 
naturalists, have adopted this denomination, it would be a diffi-’ 
cult, as well as an useless task to correct this slight mistake. 
Professor Santi, however, does not err in naming the dromedary 
the single hunched camel of St Rosso-re; but wishing to deter-' 
mine to which of the two varieties of this species it belongs, I ‘ 
agree in saying with Signior Porte, that ours are the Arabian, 
or common, or true camels, and not dromedaries^ since they at 
the first glance assimilate to the former in shape and habit. 
But, it is now time to return to the guttural bladder of the 
dromedary, the original object of this memoir, from which I 
have digressed, to enlarge on a discussion, in my opinion, not 
without utility, there being many Tuscans still uncertain of the 
appropriate name of our camel, although the question has been 
for some time decided beyond the Alps. 
From all I can collect in the various books I have consulted, 
the Bactrian^ or the two hunched camels^ never shew this sac, 
which so many have remarked in the dromedary : Ils li'mii 
point cette vessie.^ que les dromedaires font sortir de Imr houchc
