1S8 Dr Paolo Savi on the Bag^br Bladder occasionally 
should think myself inexcusable to naturalists, had I not pro- 
cured materials for illustrating and explaining the fact, placed as 
I am, in a situation the most suited to note the habits, disposi- 
tion and structure of this animal. There is, as is well known, 
near Pisa, a breed of camels pertaining to the Crown, in the 
district of San Rossore, in an extensive and beautiful plain, 
which, defended from the north winds by a mountain chain, al- 
ways enjoys a mild temperature. 
The soil of this district is chiefly sandy, and abounds in 
thickets of evergreen plants, of the species most agreeable to 
camels; hence these animals, there enjoying perfect liberty, 
suitable food, and living, in short, in circumstances almost- similar 
to those of their native country, are perfectly accustomed to the 
climate, are in perfect health, and completely perform all their 
functions, which can never be the case with camels cooped up 
in the menageries of a colder climate, almost the only situations 
under which they have been attentively examined by naturalists, 
I therefore endeavoured to profit by these favourable circum- 
stances as much as possible, especially as I frequently was among 
the camels in summer and in winter, both with the females while 
suckling their young, and with the males, either feeding at large 
in the woods, or led by the camel drivers in agricultural labours, 
and had every convenience for examining them attentively, and 
studying their natural history. And although the camel be an 
aniraaL of which much has been written, yet I have found that 
some facts have escaped other observers, and that some things 
which have been stated respecting them require correction. 
But before entering on the subject, it is necessary to ascer- 
tain to what species the camels of St Bossore belong. The best 
naturalists admit but two species of the genus Camelus, viz. the 
camel with two hunches, Camelus BajCtriamLs; BX\d. thecamel with 
a single hump, Camelus Dromedarius. As our camel is furnished 
with but one hump, it belongs to the last species; and Professor 
Santi, in a memoir Sur les Chamtaux de Pise^ inserted in the 
17th volume of the Annales du Aluseum of Paris, for 1811, has 
given it the name of Camelus Dromedarius. But Signior 
Luigi Porte, who published, in 1815, a memoir Sul Camello 
Toscano^ is of tlie opinion of Valmont de Bomare, and of divers
