So there were different observations upon something that was seen in November, 1883. These observations were Philistines in 1883. In the _Amer. Met. Jour._, 1-110, a correspondent reports having seen an object like a comet, with two tails, one up and one down, Nov. 10 or 12, 1883. Very likely this phenomenon should be placed in our expression upon torpedo-shaped bodies that have been seen in the sky--our data upon dirigibles, or super-Zeppelins--but our attempted classifications are far from rigorous--or are mere gropes. In the _Scientific American_, 50-40, a correspondent writes from Humacao, Porto Rico, that, Nov. 21, 1883, he and several other--persons--or persons, as it were--had seen a majestic appearance, like a comet. Visible three successive nights: disappeared then. The Editor says that he can offer no explanation. If accepted, this thing must have been close to the earth. If it had been a comet, it would have been seen widely, and the news would have been telegraphed over the world, says the Editor. Upon page 97 of this volume of the _Scientific American_, a correspondent writes that, at Sulphur Springs, Ohio, he had seen "a wonder in the sky," at about the same date. It was torpedo-shaped, or something with a nucleus, at each end of which was a tail. Again the Editor says that he can offer no explanation: that the object was not a comet. He associates it with the atmospheric effects general in 1883. But it will be our expression that, in England and Holland, a similar object was seen in November, 1882. In the _Scientific American_, 40-294, is published a letter from Henry Harrison, of Jersey City, copied from the _New York Tribune_: that upon the evening of April 13, 1879, Mr. Harrison was searching for Brorsen's comet, when he saw an object that was moving so rapidly that it could not have been a comet. He called a friend to look, and his observation was confirmed. At two o'clock in the morning this object was still visible. In the _Scientific American Supplement_, 7-2885, Mr. Harrison disclaims sensationalism, which he seems to think unworthy, and gives technical details: he says that the object was seen by Mr. J. Spencer Devoe, of Manhattanville. 25
