by Dr Pullas in the Kirguise fheep, may be “owing 
to some local cause. 
6th/y, Tat a temperate climate is the most fa- 
vourable for the production of wool; as extremes of | 
both heat and cold have a tendency to convert it into 
hair, or at lease into a species of wool so extreme-= 
ly coarse, as not to be easily distinguifhed from 
it.* 
8zhbly, That saline bitter pastures, have great in- 
fluence in augmenting the size of iheep, as well as 
in fattening them; ar the same time that such pas- 
tures have a particular tendency to produce the spe- 
cies of soft oily grease, which forms more especially 
on the rump and tail of the steatopyga variety of

may afford a subject for a separate difsertation. Some facts respecting 
this subject are ascertained with tolerable accuracy by experiment 5 
ethers still are doubtful, and require further elucidation, so that Isus-

+ With regard to the nutritious plants mentioned above by my 
learned friend, I can say nothing of the fhrub resembling a species of 
yobini., as he does not name it ; but I believe you have none of the 
genus to which he compares it. However, surely the mountains of 
Scotland must be well stored with Alpine plants in general, to which’ 
he attributes so much merit; and as ior the astragalr, which he single
