We had seen the thermometer at 70° below zero, at which time the Aurora was bright. We now made a few experi- ments on the effect and intensity of the cold, the results of vvrhich were as follow: With the thermometer at 62 minus, a square six-ounce bottle of sulphuric ether with a ground stopper, was taken out of the medicine chest, exactly in the same state as it had been packed at Apothecaries' Hall, viz: with the stopper down, and exposed immediately below the registering thermometer on the snow. In fifteen minutes, the interior upper surface of the sides of the bottle was coat- ed with ice, and a thick eflloresccnt sediment covered the bottom, while the ether generally appeared viscous and opaque. After having remained an hour, during which the temperature rose to 60° minus, it had scarcely changed, or, perhaps, as Mr. King agreed with me in thinking, it was more opaque. The bottle was then carefully brought into the house, and placed on a table, within four feet and a half of the fire; and though so near, and with a temperature of 32° plus, it did not recover its former clearness or purity under forty-two minutes. A bottle of nitric ether, similar in dimensions to the sul- phuric, was not changed in the same time; but after two hours' exposure it also became viscid, the temperature in the meantime having varied from 60 to 56 minus. A fluid drachm and a half of sulphuric ether was put into an ounce and a half bottle with a glass stopper; and when it had become
