has been queftioned by fome Naturalifts, yet the accu- 
rate refearch of SwamMerpam has fufficiently proved 
their real nature, and that they are furnifhed with near- 
ly the fame humours, coats, and veffels as in moft of 
the larger animals. Some authors have fuppofed the 
horns to be a kind of natural telefcopes, and that the 
animal fhortened or lengthened them according to the 
diftance of the objects to which it directed them; but 
this idea fcems to imply a more complicated ftructure 
than can be found in this organ, and, I believe, muft 
be given up as one of thofe ingenious hypothefes which 
are too frequently entertained by fpeculative enquirers. 
'The teeth of the Snail are fharp and ftrong, and all 
the internal as well as external parts of the creature 
are admirably calculated by Nature for the mode of life 
to which it is deftined. 
But the moft wonderful part of the hiftory of the 
Snail, is its manner of breeding; and I muft requeft 
my readers to fummon all their philofophical faith to 
receive the furprifing particulars. 
If the obfervations of the moft profound enquirers 
into the operations of Nature amongft the lower orders 
of animals may be depended upon, the amours of Snails 
are conducted in a manner very different from thofe of 
moft other creatures, and are always preceded by a ve- 
ry extraordinary ceremonial, which has all the appear- 
ance of a regular combat. 
When thefe animals are difpofed to love, they figni-

at each other. Thefe darts are of a very fharp form, 
and of a horny fubftance, and the animals are provided
