This collection was presented by Mr. Hoyt to the Jamestown 

 Collegiate Institute, and under the supervision of Professor Love, 

 encased in glass was deposited in the museum of that institution, 

 where it may now be inspected. 



To facilitate a better understanding of the form and structure 

 of the mastodon, we illustrate the subject by a reprint of the cele- 

 brated Cohoes specimen of the skeleton of the animal, as mounted 

 in the New York State Museum of Natural History at Albany. 

 The plate of the molar, as seen in this connection, is from a tooth 

 of the Hoyt farm collection and exhibits the conical or mastoid 

 tuberosities forming the grinding surface of the molar of the Mas- 

 todon as distinguished from the molar of the Mammoth, and giving 

 name to the former as applied by Cuvier. 



Several years later, (in July, 1888) at Bemus Point, on Chau- 

 tauqua Lake, Frank Arnold, who resided near its shore, and habit- 

 ually, in his boat, fished from its waters, had frequently observed, 

 a rod or two from shore, at a depth of two or three feet, an object 

 on the bottom which appeared to be a curiously shaped log or sec- 

 tion of the knotty limb of a tree; on removing it for examination he 

 found it to be a massive bone, which, on reference to accepted 

 authority, was decided to be the tibia (or shin-bone) of the masto- 

 don, and is probably part of the skeleton of that animal of large 

 dimensions still remaining imbedded in the soil at the bottom of the 

 lake near the place of this discovery. It doubtless became detached, 

 was thrown up, and slowly washed in shore by the agitation of 

 the waters of the lake during violent storms and by the landing of 

 steamers many times daily at this place. Other portions of the 

 same skeleton are likely to be thus recovered in the future. The 

 tibia here illustrated is described as follows: 



Length, twenty-eight inches; diameter at knee joint, ten and 

 one-half inches; diameter at ankle joint, eight inches; weight, 

 twenty-one and one-half pounds. 



A comparison of the dimensions of this specimen with reported 

 measurements of the tibia in the Cohoes skeleton exhumed in Sep- 

 tember 1866, (twenty-six inches in length) and of the Warren 

 mastodon skeleton of Warren Museum in Boston, exhumed at 

 Newbury, 1845, (twenty-eight inches in length), establishes its size 

 to be uniform with that of the latter. When clothed in flesh, they 

 were therefore respectively about nine and a half and ten and a 

 half feet in height at the shoulders, the Chautauqua Lake specimen 

 belonging to an animal of the latter dimensions. 



Next in order of discovery is the Sheridan skeleton. We are 

 indebted to George E. McLaury, Esq., of that town, for the follow- 

 ing brief particulars kindly furnished by him:
