(ours for about the same period was about 41°), and the mean 

 maximum 58° (ours 57°). Wakeham (Report of Expedition 

 in Steamship "Diana" in i8py), from June 2y to October 9, 

 1897, found a maximum temperature of 79°, a minimum of 

 27°, and a mean of 43.1°. According to the Pilot, the mean 

 temperature in 1875 for the coast between Cape Porcupine 

 and Nain was : in July 46.5° (ours 46.2°), in August 50.3° 

 (ours 49.4°), in September 44.5° (ours 43.1°). 



Our daily temperature-readings are not possessed of a 

 sufficiently assured and complete accuracy to make it desir- 

 able to give them in full. Grouped together by half-months, 

 the records, corrected so that they are fairly reliable, yield 

 the results seen in the following table. The maxima and 

 minima were given by a recording themometer, a modifica- 

 tion of Sixe's type (similar to the Miller-Casella instruments). 

 The daily range of temperature was obtained from this instru- 

 ment by determining the difference between its recorded 

 maximum for the day and minimum for the night. Average 

 (i) was obtained by determining the daily mean of the maxi- 

 mum-minimum records. Average (2) was calculated from 

 three daily readings at stated hours. The corrections were 

 made by comparison of the records of the regularly used 

 thermometers with those occasionally taken with great care 

 by aid of a fully-tested and corrected centigrade thermometer 

 loaned to Dr. Daly by the United States Coast and Geodetic 

 Survey, which, unfortunately, had to be used most of the time 

 for other purposes, and hence was not available for these 

 daily observations. 



Comparison of our averaged results with those of other 

 expeditions, as quoted above, seems to indicate that our 

 degree of error was not so large as to destroy altogether 

 the value of the table here given.
