cyclones of terrific force—water-winds of all degrees : 
water-winds at feven miles an hour; water-dorms at 
thirty-fix miles an hour : water-hurricanes at eighty miles an 
hour;—what a precarious world for the water people and 
creatures to live in ! Howling water forces raging through 
the deep of waters as the wild forces of the air hold high 
carnival beneath our fkies ! Under a condition of things like 
this, no living creature poflefled of any fpecific gravity known 
to man could exift. A fmall fifh would require to be the 
weight of an elephant: it could float only by mechanical 
flotation ; and the foundations of the mightieft iflands and 
continents of our globe would be in perpetual danger of 
being undermined and fhattered to fragments. Imagine what 
would have to be the fpecific gravity of the water-breathing 
creatures there, the men and the women. To be able to 
move about and cleave the waters with the fame facility 
that our bodies move and cut through the air, would require 
a fpecific gravity eight hundred times heavier than water, 
as our bodies in our atmofphere are eight hundred times 
heavier than air. Under the preflure of our atmofphere 
it is a very light individual that weighs only i oo lbs: but 
multiplied by eight hundred it becomes 80,000, or forty 
tons! and a lady of 200 lbs. weight in London above the 
water, would be a lady of eighty tons weight in the fub- 
aqueous London at the bottom of the sea ! 
Let not this be confidered a mere piece of extravagant 
imagination. The atmofpheric ocean in which flying crea-
