NOTE.—In 1858 (Proc. Boston Soc. Nat. Hist., vol. VI, p. 303), Dr. Skilton, of Troy, wrote that a farmer had dug up, in what had been marshy ground, 17 teeth of a horse. These, Skilton stated, belonged to _Equus major_. The teeth were greatly decayed. The writer of the report said that the enamel of the first upper molar, meaning the anterior of the six grinding teeth, measured 1.9 inches (47.5 mm.); that of the corresponding lower teeth 2.33 inches (58 mm.). If these measurements were taken correctly, they indicate a horse much larger than any yet known, unless it be _Equus giganteus_ of Texas. There is no evidence that Dr. Skilton had made any serious study of the dentition of horses and the teeth were probably those of a domestic horse, or even of some other animal. In 1884 (Trans. Linn. Soc. N. Y., vol. II, p. 47), Dr. C. Hart Merriam, in his paper “The Vertebrates of the Adirondack Region,” stated he had examined several fossil molar teeth of _Equus major_ exhumed at Keenes Station, near the Oswegatchie Ox Bow, in Jefferson County, New York. He compared them with the corresponding teeth of an immense dray horse and found them much larger. Professor G. C. Manse, of St. Lawrence University, Canton, New York, sent me for examination 4 upper teeth of a horse which must be those examined by Dr. C. H. Merriam. They are labeled as having been collected at Gouverneur, a town not far from Keenes Station. After a careful study of these teeth and comparison with those of the domestic horse, the writer concludes that they belonged to the latter. Domestic horses are known to have larger teeth. Professor Manse has unfortunately been unable to trace the history of the teeth back to Dr. C. C. Benton, of Ogdensburg, who showed them to Dr. Merriam. NEW JERSEY. (Map 17.) 1. _Swedesboro, Gloucester County._—In 1868 (Cook’s Geol. New Jersey, p. 741), Cope stated that _Equus complicatus_ was represented in New Jersey by a series of teeth obtained while a mill-dam at Swedesboro was being cleared. No further information has been secured. At the Academy of Natural Sciences of Philadelphia, the writer has seen a horse-tooth labeled as coming from the town named; but whether or not it is one of those referred to by Cope it is impossible to say. 2. _Fish House, Camden, Camden County._—In 1869 (Trans. Amer. Philos. Soc., vol. XIV, p. 250, fig. 55), Cope wrote that a partial skull of _Equus fraternus_ had been found at Fish House in a blackish clay at a depth of 20 feet from the top of the clay. Over the clay was imposed a bed of sand from 8 to 15 feet thick. This important skull appears to have been lost (fig. 7).
