2. I had notice of a Fhcenomemn^ that I judged odd and confi- 
derable in fearching into the nature of Cold^ which is 5 That there 
is a litle Lake in Straherrick on the Lord Levels Lands, which ne- 
ver freezes all over ('even in the moil vehement frofts, ) before 
bruary^ but one nights frofi: there-after will freeze it all over , 
and two nights then will make the Ice of a very confiderable thick- 
nefs. This I did inquire after very follicitoufiy from thehonefiefl 
and fobereft of the adjoyniog Inhabitants, and it was verified by 
fo many,thac there was left no place to doubt the truth of the mat- 
ter of faft. I have fince heard of two other Lakes, one of which 
is on Lands belonging to my felf, called Loch Monar , of a pretty 
largenefs, which fteddily keeps the fame method, and I have in- 
quired after it bymany , who have affirm'd it to me on their own 
knowledge. There is another litle Lake in Straglafi at Glencanich 
on Lands belonging to one Chiplm\ the Lake lies in a bottom 
'twixt the tops of a very high hill, £0 that the bottom it felf is very 
high! This Lake never wants Ice on it in the middle, even in tlie 
hotteft Summer, though it thaw^s near the edges: And this Ice is 
found on it, though the Sunby reafon of the reflexion from thehills 
in that Country is very hot, and Lakes lying as high in the neigh* 
bourhoodhavenoflichphcsaomenon* 'Ti^ obfervable alio, that 
I about the borders of this Lake the Grafs keeps a continual ver- 
I - dure, as if it were in a conftant Spring, and feeds and fattens beafls 
j more in a week, then any other Grafs doth in a forthnighr» The 
I matter of faft I have fully examined in both thefe ; but to hit the 
caufc, requires a better Philofopher then I am, &c. Februar, S.
