I found factors in table 8 [huge?] 356, correction
for temperature, for level of the sea, Table
4, Page 359, in Buchan's book of meteorology,
would have used Loomis, but in correcting
for the level of the sea, the temperature
varies only between 40 & 90, the [illegible] has stood
lower several times, and I had to take
the other [table?]. The height here above
the Level of the sea is 660 ft.
I took the proportional parts of the factors.

I hope you will let me know, the
result of your examination.
