which deprived him instantly of sense. From John Lloyd, Esq. 
he had learned another case:=-A negro working in his field was 
seen suddenly to fall, uttering a shriek ; on approaching him, it 
was found that he had struck off the head of a very large rattle- 
snake, the body of which was still writhing. On recovering, he 
said that he had shrieked with horror on discovering the snake, 
and at the same instant had been overpowered by a smell that 
took away all his senses. Mr. Nathaniel Barnwell hada negro, 
who could, from the acuteness of his smell, at all times discover 
the rattle-snake within a distance of 200 feet, when in the exer- 
cise of his fascinating power, and when traced by this sense, some 
object of prey was always found suffering from this influence, To 
these facts Major Garden added some anecdotes collected from 
Vaillant’s: travels and other sources, corroborating his. theory. 
When gorged with food the serpent is supine. It is only when 
under the.stimulus of hunger that he exerts this fascinating fa- 
culty. c—

ninety feet above the stream tide. It is to be of cast iron, upon 
the principle of suspension..
