The duplicature of the cheeks of this animal having been extended outwardly in drying the skin, was left in its rigid state, giving it an unnatural appearance, which doubtless led to the incredulity of Cuvier when he saw the figure and description of Dr. Shaw. Dr. Mitchell was led to a similar error of opinion, at first, as to the natural position of these bags; but afterwards, when the matter was explained to him, corrected this mistaken notion.

By reference to the descriptions of Mr. Barnes and Mr. Lea, recited above, the number will be seen to have exceeded this estimate.

Memoranda of Climatic Phenomena and the Distribution of Solar Heat in 1820. By Henry R. Schoolcraft.
The influence of solar heat on the quantity of water which is discharged from the great table lands which give origin to the sources of the Mississippi was such, during the summer months of 1820, that, on reaching those altitudes in latitude but a few minutes north of 47°, on the 21st of July, it was found impracticable to proceed higher in tracing out its sources. Attention had been directed to the phenomena of temperatures, clouds, evaporations, and solar influences, from the opening of the year, but they were not prosecuted with all the advantages essential to generalization. Still, some of the details noticed merit attention as meteorological memoranda which may be interesting in future researches of this kind, and it is with no higher view that these selections are made.
