168 RECORD AND RESULTS OP 



Smith Strait ; the interval between these dates was consumed in the attempt of 

 beating in and through the strait. During this interval the climatic relations were 

 so nearly the same as those at Port Foulke that we may conveniently commence 

 the meteorological record with September 1, 1860. The observations extend to 

 July 14th (10 A.M.), 1861, at which date the vessel was unmoored and pulled 

 out of the harbor ; crossing the strait, the schooner anchored for several days in the 

 vicinity of Cape Isabella; on the 29th she was off Gale Point; and on the 31st 

 some short distance to the southward of Cadogan Inlet. AVe may, therefore, com- 

 bine, without much risk of error, the recorded observations during the latter half of 

 July with the preceding record, and thus form a continu.ous meteorological record 

 for Port Foullie, extending over eleven months. A proper method of interpolation 

 will enable us to deduce a mean A^alue for each meteorological element for the 

 twelfth month, and the annual mean values may safely be made out. 



The results will be further illustrated by comparison with those obtained from 

 Dr. Kane's^ and Sir F. L. McClintock's" expeditions, as published by the Smithsonian 

 Institution in 1859 and 1862. 



Takiiig the refraction into consideration, the sun's upper limb would, in the lati- 

 tude of Port Foulke, astronomically disappear after October 25th noon, and reappear 

 at noon February 15, thus remaining below the horizon for 113 days, or nearly 

 three and two-third months. Owing to the surrounding cliffs the sun did not make 

 its appearance at the harbor until February 18. 



TEMPERATURE. 



The expedition was supplied with about two dozen thermometers of different 

 kinds, graduated according to Fahrenheit's scale, excepting two, Avhich were divided 

 in degrees of Reaumur. Some were spirit, others mercurial thermometers ; there 

 was also one metallic thermometer. Three of the instruments were considered of 

 standard excellence, and of these No. 3 was selected by Mr. Sonntag as the 

 standard, to which accordingly the indications of all others will be referred. 



Thermometers Nos. 1, 2, 3, are standard instruments. No. 3 was selected as the 

 most reliable. (They are, no doubt, spirit thermometers.) 



Nos. 4, 5, 6, ordinary thermometers (supposed spirit thermometers). 



Nos. 7, 9, mercurial thermometers. 



Nos. 8, 10, 12, 13, ordinary thermometers. 



M, a metallic thermometer by Beaumont, of New York. 



1705, 1657, maximum thermometers; they are mercurial.
