242 DR SUTHERLAND SIMPSON ON 
After arriving in Edinburgh the observations were continued, with one day’s 
interruption (July 6), till July 10, the daily routine being not much different from 
the same in Ithaca. From July 17 till August 10 the time was spent in the 
Orkney Islands, somewhat over 200 miles farther north than Edinburgh, but practically 
in the same longitude, and here another series was taken from August 3 to 9 
inclusive. 
On August 5 I walked around one of the islands, a distance of about twelve miles, 
over rough ground, temperature records being taken at intervals of one and a half hours, 
and a glance at the chart (fig. 3) will show the effect on the body temperature. On 
August 8 I remained in bed the whole day, and abstained from food entirely from 
9 p.m. August 7 till 8am. August 9, at the same time making an effort to restrain 
muscular action as far as possible. As these records are important for comparison with 
others taken subsequently under somewhat similar circumstances in Winnipeg and in 
Ithaca, they are given below together with the room temperature, which was practically 
the same as that of the outside air, since all the windows of the sleeping-room were 
open. Readings were taken every hour. 
The journey westward was begun on August 14, when the train left Edinburgh 
for Glasgow at 6 am. The steamer (s.s. Jonzan, Allan Line) sailed from Glasgow 
about 10 a.m. and from Greenock about 2 p.m. the same day. The weather was fine, 
and the voyage uneventful until we ran into fog and ice off the Newfoundland coast, 
when we were compelled to go dead slow or to drift for almost two days (August 20 
and 21). On the evening of the 21st we entered the Straits of Belle Isle, and from 
that time onwards it was full speed ahead until Quebec was reached about 9 p.m. on 
August 23. That night was spent on board ship moored at the quay, and at 7.30 a.m. 
we left Quebec and steamed up the St Lawrence to Montreal, where we disembarked 
about 7 p.m. on August 24. That night and the following day was spent in Montreal, 
and at 10.30 p.m. on August 25 the train to Winnipeg was taken, where it arrived at 
9.20 p.m. on August 27. 
During the whole journey from Glasgow to Winnipeg the observations were kept 
up without interruption on steamship and train until noon August 30, three days 
after arrival in Winnipeg. 
On August 29, the second day in Winnipeg, I repeated the routine of August 8 
in the Orkneys, remaining in bed the whole day without food and voluntarily inhibiting 
muscular movement as far as possible. The light was partly obscured by the close 
proximity of a brick wall to the single window of the room I occupied, and this, 
together with the fact that no person visited me, was particularly favourable for my 
purpose, which was to secure as completely as possible bodily and mental quiescence. 
The rectal, mouth, and axillary temperatures were recorded hourly together with the 
temperature of the room (see Table II.). ' 
On the return journey from Winnipeg to Ithaca several stops were made on the 
way and the observations were discontinued until September 10, the day after arriving
