!>y the little tare which they exercise in represent- 
iiiij these animals, and in preparing them for being 
exhibited in their different collections.” This leads 
l)im to a disquisition on the best modes of stuffing 
and preserving animals, by taking casts, 8cc. all 
of which appear admirable, and being the result of 
much experience and ingenuity, merits the especial 
regard of those engaged in such labour. 
One of the investigatlims which, at this era of his 
history, most dee|ily interested Camper, related to a 
remarkable and highly interesting peculiarity in the 
structure of birds. In all animals, the osseous or 
bony system subserves two grand purposes. As it 
includes all the hard and more solid parts of the 
machine, it s.cX% first, as a substantial framework, to 
vvhicli the soft parts are attached, and, in conjunc- 
tion with which, the process of locomotion is ac- 
complished ; and, secondly, it .affords a covering and 
defence to the many very delicate internal organs by 
winch the phenomena of life are maintained. The 
lungs, again, are those organs by which, in all the 
higher classes of animals, respiration is performed, 
the ]iurification of the blood is effected, and the vital 
heat is preserved. These, in general terms, are the 
principal functions performed by the osseous and re- 
spiratory apparatus in man and quadrupeds. Now, 
up to the period under review, it had not been sus- 
])ected that there was any marked peculiarity in the 
uses to which in birds tliese parts were appropriated. 
Camper, however, whilst engaged in some minute
