cannot endure even the moderate heats of the valley of Nep£l, and the Lama of 
Digerchi’s pet, though familiar with confinement, and most comfortably lodged 
and fed, died at the very commencement of the hot season, before lie had been with 
us above a month, and while the maximum of Fahrenheit, in the stable lie tenanted, 
was only 80° ; a temperature, besides, seldom reached for 2 hours a day, or tor - 
days of that month, ( March.) , . , 
1 shall conclude this account with a detail of the dimensions and colours of the 
individual above noted, which I examined alive, and after death forwarded its skin 
to Dr. Abel, who added some technical particulars to my account, and did me the 
honor to name the species after me. Grey blue is the general colour of the hair 
throughout nine-tenths of its extent, from root to tip, as well as exclusively so ot 
the wool beneath the hair. This radical and prevalent color is, however, but dimly 
seen through the external or superficial hues with which it is overlaid j and whic i 
hues, upon the superior parts of the animal, are, pale fawn red ; upon the inferior 
parts and insides of the limbs, and ears, white. The shoulders are faintly marked 
by a tracing of color lighter than that of the surrounding parts. Down the fronts ot 
all the 4 legs, runs a black line, reaching from the body to the hoots in the case of 
the two forelegs, but to the knees only in regard to the two bind ones.s 
The forehead is perfectly black, and a fringe of the same hue proceeding fiom the 
bottom of the frontal skin passes round the outsides of those tufts which I have 
mentioned as being placed beside the nostrils. These tufts, as well as the rim sur- 
rounding them, are black, so also are the bristles of the mouth and lips : bu : those 
few depending from the lower lip are white. The lips themselves (upper as well as 
lower one) are white. The roof of the mouth is colourless : the horns and hoofs, 
full black ; the irides dark brown: the genitals black.

yj .Interesting Experiments with Canal-Boats. 
[From the Scotsman Newspaper.] 
We regard the experiments described below as extremely important. If the re- 
sult iJ correctly stated, an«l if no counteracting disadvantage has escaped notice, we 
think these experiments may be said to have added a million sterling to the value 
o canal property in Great Britain, since they must at no distant period, add fifty or 
a hundred XmJand pounds to the annual dividends. Nothing can be more para- 
doxical or startling in appearance than this result ; and yet our knowledge ot the 
manj unexpected "truths in mechanical science which experiment has brought to 
light! will not permit us to reject it as incredible. It is this ; that the surge gene- 
rated in a canal , by the motion of a boat, and which is so destructive to the banks , m 
3 Since writing the above, I have procured another skin of a very old male. 
The ruddy tint of the upper surface is in this specimen nearly merged in hoary grey 
upon the neck : hind head and buttocks behind, and the black lines of the legs reach 
to P the hoofs in all 4 legs. The white of the insides of the ears and belly not white, 
but whitish only, with a subtint of buff.
