omitted the corrections of parallax and aberrations, not intending to get more than a rough approximation. I find to my sorrow that they do not agree with those from my own observations. I shall look over them again next week.
"At noon I ran around and did up several errands, dined, and was back again at my post by 1.30. Then I looked over my morning's work,--I can find no mistake. I have worn myself thin trying to find out about this comet, and I know very little now in the matter.
"I saw, in looking over Cooper, elements of a comet of 1825 which resemble what I get out for this, from my own observations, but I cannot rely upon my own.
"I saw also, to-day, in the 'Monthly Notices,' a plan for measuring the light of stars by degrees of illumination,--an idea which had occurred to me long ago, but which I have not practised.
"October 23. Yesterday I was again reminded of the remark which Mrs. Stowe makes about the variety of occupations which an American woman pursues.
"She says it is this, added to the cares and anxieties, which keeps them so much behind the daughters of England in personal beauty.
"And to-day I was amused at reading that one of her party objected to the introduction of waxed floors into American housekeeping, because she could seem to see herself down on her knees doing the waxing.
"But of yesterday. I was up before six, made the fire in the kitchen, and made coffee. Then I set the table in the dining-room, and made the fire there. Toasted bread and trimmed lamps. Rang the breakfast bell at seven. After breakfast, made my bed, and 'put up' the room. Then I came down to the Atheneum and looked over my comet computations till noon. Before dinner I did some tatting, and made seven button-holes for K. I dressed and then dined. Came back again to the Atheneum at 1.30, and looked over another set of computations, which took me until four o'clock. I was pretty tired by that time, and rested by reading 'Cosmos.' Lizzie E. came in, and I gossiped for half an hour. I went home to tea, and that over, I made a loaf of bread. Then I went up to my room and read through (partly writing) two exercises in German, which took me thirty-five minutes.
"It was stormy, and I had no observing to do, so I sat down to my tatting. Lizzie E. came in and I took a new lesson in tatting, so as to make the pearl-edged. I made about half a yard during the evening. At a little after nine I went home with Lizzie, and carried a letter to the post-office. I had kept steadily at work for sixteen hours when I went to bed."

CHAPTER II
1847-1854
MISS MITCHELL'S COMET--EXTRACTS FROM DIARY--THE COMET
Miss Mitchell spent every clear evening on the house-top "sweeping" the heavens.
No matter how many guests there might be in the parlor, Miss Mitchell would slip out, don her regimentals as she called them, and, lantern in hand, mount to the roof.
On the evening of Oct. 1, 1847, there was a party of invited guests at the Mitchell home. As usual, Maria slipped out, ran up to the telescope, and soon returned to the parlor and told her father that she thought she saw a comet. Mr. Mitchell hurried upstairs, stationed himself at the telescope, and as soon as he looked at the object pointed out by his daughter declared it to be a comet. Miss Mitchell, with her usual caution, advised him to say nothing about it until they had observed it long enough to be tolerably sure. But Mr. Mitchell immediately wrote to Professor Bond, at Cambridge, announcing the discovery. On account of stormy weather, the mails did not leave Nantucket until October 3.
Frederick VI., King of Denmark, had offered, Dec. 17, 1831, a gold medal of the value of twenty ducats to the first discoverer of a telescopic comet. The regulations, as revised and amended, were republished, in April, 1840, in the "Astronomische Nachrichten."
When this comet was discovered, the king who had offered the medal was dead. The son, Frederick VII., who had succeeded him, had not the interest in science which belonged to his father, but he was prevailed upon to carry out his father's designs in this particular case.
The same comet had been seen by Father de Vico at Rome, on October 3, at 7.30 P.M., and this fact was immediately communicated by him to Professor Schumacher, at Altona. On the 7th of October, at 9.20 P.M., the comet was observed by Mr. W.R. Dawes, at Kent, England, and on the 11th it was seen by Madame Rümker, the wife of the director of the observatory at Hamburg.
