180 Effect of Temperature on human feeling. 
rosin bubbles is beens correct. A little il came 
nning to me one evening, with, as she said, about two 
thirds of a string she had formed from the rosin of one of 
the stove lamps, while burning. It consisted of twenty-two 
or — beads, each about one third of an inch long 
and one fourth of an inch in diameter, connected together 
by a fine “bre; a than one eighth of an inch long. In 
passing my eye repeatedly from one end to the other, I 
uld not discover any difference in cs length, form, or 
size, or in the distance they were apart, except two or three 
at one end. Considering that the temperature of the rosin, 
and the materials, and the pressure are always the same, I 
have no idea what governs the formation of the bead differ- 
ent from that of the fibre. When I mentioned it to you, I 
did not suppose it was new, and if so, I thought it very un- 
certain whether you would think it worth noticing in the 
Journal. 
23. Effect of temperature on hudion feeling. 
. —.. rg in a letter to the Editor, remarks * 
“In England, the only natural temperature that is agreeable’ 
lies a "60 and 70°, so that when the thermometer is 
above 70, the inhabitants begin to feel uncomfortably warm, 
and when i it is below 60, they begin to approach the fire. In 
this clima: te, (lat. 35,40, N. long. 79, 3, W.) we do not feel 
dseoriforiably warm until the thermometer is above 80; 
and we begin to kindle fires when it is below 70. It would 
seem therefore that our standard in this respect is 10° high- 
er than it is in England ; and that we do not suffer more by 
a heat of 90, than the people of England do by a heat of 80. 
Dr. Black also remarks, that, in Scotland, the thermome- 
ter rises, in moderately warm summer air, to 64°. Accor- 
ding to this account, what would be esteemed moderately 
warm summer weather in Scotland, would he penne 
= to the external circumstances in which it is placed.
