'Rattlejnake. Head flatted : body

by loofe horny joints, and varying

even 70. The one here figured is

This Snake is common in the 
hilly uncultivated parts of N. 
America: moves flow: is vivi- 
perous, and brings forth in June, 
about twelve young ones. When 
provoked, fhakes the rattle at the 
end of the tail; making a noife 
with it like that of a Ipinning 
wheel. When its bite is in the 
flefh only, it is cured by cutting 
Out the part, or fucking the 
wound; but if in a vein or artery, 
it is immediate death. Its power 
to facinate with its eyes both 
birds and fmall quadrupedes, 
caufing them to run into its 
mouth, is univerfally afferted and 
believed in America,
