Dr. Kane, in his Second Arctic Expedition, found the thermometers
beginning to show unexampled temperature: they ranged from 60° to 70°
below zero, and upon the taffrail of the brig 65°. The reduced mean of
the best spirit-standards gave 67° or 99° below the freezing point of
water. At these temperatures chloric ether became solid, and chloroform
exhibited a granular pellicle on its surface. Spirit of naphtha froze
at 54°, and the oil of turpentine was solid at 63° and 65°.
