or quoits. The muscular exercise indulged in was probably not equal to, and certainly 
not in excess of, that taken in Ithaca, but there was greater mental relaxation. The 
weather was fine from land to land and not the slightest suspicion of sea-sickness was 
experienced. ; 
The eastward voyage was begun on June 25, about 11.45 p.m., when the train left — 
Ithaca, and New York City was reached shortly after 8 o’clock next morning. The 
steamer (s.s. Caledonia, Anchor Line) sailed from New York for Glasgow about 
2.30 p.m. on June 26. Four observations were made on the train and two in New 
York City for the sake of keeping up the continuity. Glasgow was reached about 
4 p.m. and Edinburgh at 9 p.m. on July 4, the voyage thus lasting practically 
eight days. : 
The longitude of Ithaca, N.Y., is 76° 29’ W., and the local time is therefore 5 hours 
5 minutes and 56 seconds—practically 5 hours 6 minutes—behind Greenwich time. 
The clock time at Ithaca is about 6 minutes ahead of the true local time. astern — 
standard time is used at Ithaca, and this is the local time for stations on long. 75° W., 
which is 5 hours behind Greenwich time. My watch was adjusted for this difference, 
and the observations were made according to the correct local time at Ithaca. The 
longitude of Edinburgh is 3° 10’ W., and the local time about 12 minutes behind 
Greenwich time, so that the difference between Ithaca and Hdinburgh local time is 
4 hours 54 minutes. 
On the Atlantic voyage the ship’s position at noon was posted each day, and from 
the longitude given the local time was obtained. This was only correct for noon, how- 
ever, but it was known that the time gained in a day’s run east would be a little over 
half an hour, and, assuming that the vessel’s speed was uniform, allowance could be 
made for the gain in the interval between each set of observations. This only amounted 
to a few minutes, however, and for my purpose it was immaterial whether this error 
was accurately corrected or not. The readings were taken usually at the hours stated, 
but on some occasions this was not possible and a variation of ten minutes to one side 
or the other was not considered sufficient to affect the results appreciably. 
The figures obtained for the rectal, mouth, and axillary temperatures are given in 
degrees centigrade in the subjoined table, together with the temperature of the air, the 
local time, and, after the eastward journey was begun, the corresponding time at Ithaca, © 
the starting-point. The remarks, necessarily brief, may be suflicient to show how the 
subject was employed for some time immediately preceding the observations.
