90 - Report of tlw Broivn-Harvard Expedition. 



Temperature. — In spite of the cold Arctic current that 

 sweeps southward along these shores, the summer was, on 

 the whole, very comfortable and fairly uniform in tempera- 

 ture. The observations made by the expedition suffered 

 considerably in accuracy from the fact that the thermometers 

 used were not wholly reliable, and from the impossibility of 

 finding on the ship any situation where the instruments could 

 be wholly shaded from the sun and have free circulation of 

 air about them. To some extent the observations could be 

 corrected by the aid of other observations made at irregular 

 intervals for other purposes by Dr. Daly, using a thoroughly 

 reliable thermometer. The results thus attained, while not 

 entirely accurate, are yet of some value in judging the sum- 

 mer temperature of the Labrador coast. The highest tem- 

 perature recorded by the instruments was 78° ; the probably 

 highest actual (corrected) temperature was 72°. Tlie lowest 

 temperature was 30.5°. The average was 46°. There were 

 only five days recorded, and probably only one actually, when 

 the maximum exceeded 70°. On about 33 days, or one-third 

 of all, the maximum was less than 50°. On only 6 days was 

 the minimum below 32°, but on 45 days it was below 40^^. 

 The average daily range of temperature was 13°, the highest 

 range 25.5°, the lowest 4.5°. 



Of the temperature in the interior, north of Lake Mis- 

 ^assini. Low says that 80° is exceeded on only a few days 

 during the summer season; that 45° below zero appears to 

 be the minimum winter temperature of most years; and that 

 the mean temperature at the lake in 1885 was: for June 

 53.1°, for July 59.9° (ours was 46.2°), and for August 56.7° 

 (ours 49.4°). Bryant found the minimum temperature for 

 his journey 29°, the maximum 82°, the mean minimum 42°
