Shepard 3 refers to a note upon the fall by Vaux and McEuen 2 but the reference given by 

 Shepard must be incorrect as no mention is made of the meteorite in the place quoted. Shepard's 

 account is as follows : 



I am indebted to Dr. Elwyn, the treasurer of the association, for a reference to the notice of the meteorite" of Deal 

 by Mr. Robert Vaux and Dr. Thomas M'Euen, published in volume 16, page 181, of the transactions of the Academy 

 of Natural Sciences (Philadelphia); and still further to the curators of the academy for a few grains of the stone, 

 detached from their specimen (of rather more than half an ounce weight), which has enabled me to extend the account 

 of its properties beyond the following brief remark, which is all that is embraced on this head in the paper above 

 referred to, viz: "The stone is 3 inches in its greatest length, and the surface black with many indentations." 



Its specific gravity is 3.25 to 3.30. 



Its coating is perfectly black, but without the glassy luster. In some spots it penetrates by narrow veins and chinks 

 into the mass of the stone for a slight distance. 



It is of a light color within (destitute of rust points), and has a vitreo-pearly luster. Nickeliferous iron is dis- 

 tributed through it in minute shining globules, with here and there bronze-colored specks of magnetic iron pyrites. 

 The stone is slightly coherent, and appears to be destitute of rounded concretions. 



The metallic portion is rich in nickel. The earthy part is readily attacked by hydrochloric acid; and the solution 

 formed contains silica, oxide of iron and magnesia, apparently in the proportions of howardite. 



The stone may therefore be regarded as nearly identical with that of Castine (May 20, 1848) and of Poltawa (March 

 12, 1811). 



Brezina 4 classed the meteorite as an intermediate chondrite. Nothing further seems to be 

 known of the meteorite. Wulfing 6 accounts for 10 grams, of which Paris possesses 5 grains, 

 and the Shepard collection in Washington 4 grams.

This meteorite was described by Ho well * as follows: 



This aerolite fell in the village of De Cewsville, Ontario, Canada, about 2 p. m., January 21, 1887, striking in the 

 ditch on the south side of the street known as Talbot Road, opposite lot 43, concession 1. The ditch at the time con- 

 tained about a foot of water from a recent thaw, which was covered with thin ice. The meteorite made a hole in this 

 ice about a foot in diameter. The whizzing noise in the air and the splash in the water were heard, and the latter 

 was seen by a Mrs. Leonard Strohm, who was walking along the middle of the street and was only about 15 feet distant. 

 Her first thought was that some one had thrown a snowball. The noise made by its passage through the air seems to 

 have been heard with about equal distinctness by two men who were engaged in conversation, Mr. Drinkwater and 

 Mr. Jacob Strohm, one sitting in his sleigh in the middle of the road and the other standing by a pump in his barn- 

 yard, on the south side of the road, about 150 yards west of where the meteorite fell. This fact, together with the 

 further fact that the meteorite, after striking the ice and frozen ground in the bottom of the ditch, seems to have passed 

 3 or 4 feet to the eastward, indicates pretty clearly that it came from the west, and the impression of at least one of 

 the persons who heard it, Mr. Strohm, whom I saw and questioned, was that it came from the west or a little north 

 of west. Search was at once made for the stone by Mr. Strohm and others, but without success, and the spot where 

 it struck was marked by cutting a notch in the fence near by. 



After the melting of the snow and ice the stone was found by William Kinear while on his way to school, on the 

 morning of February 16, about 3 or 4 feet to the east of where it struck. 



As the specimen has been kept intact, no analysis has been made of it. 



Its specific gravity, 3.52, is somewhat greater than most aerolites and it doubtless contains a little more iron than 

 meteorites of its class.
