bers, Mr. George N. Lawrence. The phalanx has exactly the same appearance and 

 texture as the specimens of Jefferson, and as observed by Mr. Cooper, probably 

 belonged to the same individual skeleton. 



4. The tooth, and portion of claw described by Dr. Wyman, from the neighbor- 

 hood of Memphis, Tennessee. These have been received through the kind attention 

 of my friend, Mr. J. D. Dana, and are loaned from the cabinet of Prof. B. Silliman, 

 Jr. The tooth is a first superior molar, is of large size, and is dull ferruginous in 

 color. The portion of a claw is the ungual process of the median digit of a young 

 animal, having the epijihysis detached and lost. It is of a dirty yellowish-white 

 color, and is unchanged in its original texture. 



5. A number of bones of an adult skeleton, which were discovered by Dr. M. W. 

 Dickeson, in the vicinity of Natchez, Mississippi, associated with remains of the 

 Mylodan, Mastodon, Equus americanus, Bootherium, Oervus, Ursus, Tapirus, etc. 

 They were obtained, according to Dr. Dickeson, from a stratum of tenacious blue 

 clay, which underlies the drift east of Natchez.^ 



The specimens, which are now preserved in the museum of the Academy of 

 Natural Sciences, are compact, firm, and heavy, and are of a deep brown color, from 

 the infiltration of oxide of iron.^ They consist of a skull nearly entire, containing 

 on one side the anterior three molars, and on the other the posterior four ; the 

 metacai'pal bone and phalanges of an index finger ; the first and ungual phalanges of 

 a median finger ; four carpal bones; portions of both scapulse; a clavicle ; a fragment 

 of the sacrum; small fragments of both innominata ; several fragments of ribs ; and a 

 hyoid bone. 



6. A first superior molar tooth, and the fragment of a rib, and of an ungual pha- 

 lanx, discovered by Dr. Dickeson, near Natchez, Mississippi, but not with the 

 preceding. The three specimens are white, chalk-like, and friable, and apparently 

 belonged to the same individual. 



7. A first superior molar of the right side ; a fourth upper molar ; all the phalanges 

 of the annular, median, and index fingers, and the auricular and annular metacar- 

 pals of the left side ; and a right os femoris. These apparently belonged to four 

 distinct individuals ; and they were discovered in Adams County, Mississippi, and 

 were kindly loaned to me by Col. B. L. C. Wailes, of the latter State. Most of 

 the specimens are in an admirable state of preservation. 



8. A supposed third superior molar tooth from Tuscumbia County, Alabama, 

 loaned by my friend Prof. Jeffries "Wyman. 



9. A first and a third superior molar, fi'om one individual, and a second superior 

 molar, from a second individual, from Natchez Bluffs, Mississippi, loaned to me by 

 Prof. Wyman. 



10. A number of bones derived from a single skeleton, as follows : A nearly 

 entire skull and lower jaw; the atlas, axis, and three other cervical vertebrae; one 

 dorsal, one sacral, and one caudal vertebra, and small fragments of several others;

^ With these specimens, and presenting the same general appearance of color, compactness, &c., was 

 discovered the so-called fossil human innominate bone. — Ibid. 107.
