480 Liffect of Temperature on human feeling? | - 
Tn a letter, dated March 28th, 1920, Mr. Morey replies : 
“The cause you assign for the permanent formation of the 
rosin bubbles is undoubtedly correct. A hittle girl came 
running 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 burnmg. It consisted of twenty-two 
or twenty-three beads, each about one third of an inch long 
and one fourth of an inch in diameter, connected together” 
by afine fibre, less than one eighth of an inch long. In 
passing my eye repeatedly from one end to the other, I 
could not discover any difference in their 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, andthe 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 human feeling. 
Professor Olmstead, in a letter to the Editor, remarks * 
“In England, the only natural temperature that is agreeable: 
lies between 60 and 70°, so that when the thermometer is 
above ‘/0, the inhabitants begin to feel uncomfortably warm, 
and when it is below 60, they begin to approach the fire. In 
this climate, (lat. 35,40, N. long. 79, 3, W.) we do not feel 
uncomfortably warm until the thermometer is above 80; 
and we begin to kindle fires when 11 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 ihe people of England do by a heat of 80. 
Dr. Black ae remarks, that, in Sea the thermome- 
_ ter rises, m moderately warm summer air, to 64°. Accor- 
ding to this account, what would be esteemed moderately 
warm summer weather in Scotland, would be considered 
cool autumnal weather in this climate, when the presence of 
a fire would be quite comfortable, and almost necessary. li 
seems moreover agrecable to the analogy of nature, thatthe 
animal system should accommodate itself, in some meas- 
ure, to the external circumstances in which it is placed.
