of Crabs and Lobfters, &'c. depends not upon their Celerity, and as 
thefe inhabit the Cavities of fubmarine Rocks and Cliffs, where their 
Enemies often lurk under the fame Shelter ; to prevent therefore a fudden 
Surprize from any of thefe, Providence hath not only guarded them 
with a ftrong fhelly Covering, and often Prickles ; but hath fo commo-

preffes it,
