Peruvian slaves. The wool of the paco was introduced into England by Sir Titus 
Salt, who, at Saltaire, built factories of immense size, and inaugurated a new and 
immense industry. The wool, as used in Peru, furnished such marvellously fine 
products as to vindicate the 
enterprise of Sir Titus 
Salt. The famous merino 
sheep yield no such quality 
of material, and those who 
like the best of clothing 
may well recognize the ser¬ 
viceableness of the paco. 
When shorn, the fact that 
the paco belongs to the 
same family as the camel 
becomes instantly and 
almost comically evident to 
any one. The paco is to 
be found in zoological gar¬ 
dens, but visitors may well 
be cautious of too near ap¬ 
proach, as it is given to 
the very filthy habit of ex¬ 
pectorating its food upon 
■any one who may excite 
its enmity, which a near 
approach is likely to do. 
It is kept in flocks, is 
sheep-like in appearance, 
and its wool, (which it 
never sheds) is in great 
demand for the m a n u - 
facture of a superior quality 
of blankets. The fleece is 
taken every year, and the 
hair grows to the length 
of some eight inches. * The 
fossil forms of the suidse 
and camels are the pcebro- 
therium , which has the 
typical teeth of the auche- 
nia; the protolabis and 
procamelus , which lack the 
incisor teeth of the camel 
molars, having three only.

The Kanchil ( Tragulus kanchil ) is Malayan in its habitat, and belongs 
to the smallest sized family of ruminating animals. Its delicate head is pointed, 
the body arch-like, legs slender, and hoofs small. Its motion is that of a 
bounding ball rather than walking, running, or leaping. It sleeps resting 
and the pliauchenia which varies in point of pre-
