CAIRO.
Reaching Cairo, I found Dr. T. E. Maclean from Thebes, with good instruments. He kindly compared
mine with his, and gave me the following results:—The difference between my aneroid (Casella)
and his is very slight, varying generally from 0.05 to -0.10. He advises me to neglect this
slight difference. The dry bulb is, on the whole, a little higher than his; and we have not
sufficient observations for the wet bulb. The pocket thermometer wants correction; it reads from
+1 deg. to +2 deg. 15'.
