138 ANIMALS KILLED IV, 
dry and rigid as wheel animals are among the 
fand? May we conclude, and conclude with rea- 
fon, that in them and other refurgent animals, 
life is entirely gone, not only becaufe the reci- 
procal aétions of the fluids and the folids is de- 
ftroyed, but becaufe the fluids are entirely eva- 
porated, and becaufe drynefs and rigidity has 
changed the natural ftate of the folids? If we 
faw a {tiff and contraéted frog, toad, or newt, 
gradually revive when put in water, as we fhould 
call it a real and-abfolute refurrection, fo fhould 
we call that which happens to refurgent wheel 
animals a real and abfolute refurrection alfo. 
But it is time to refume the hiftory of thefe 
wonderful animalcula: We have already defcrib- 
ed their figure and properties, but we have not 
yet examined their organs feparately, which is 
effential before becoming well acquainted with 
both. By thefe I mean the heart, the two 
trunks, and the wheels, acting at the vortices, I 
could not properly do this before, becaufe it 
would have obliged me to deviate from my in- 
tended plan, which led to the relation of fome 
facts following the order of time when they had 
occurred. It was in the profecution of my ob- 
fervations, that the animal exhibited all the 
three organs. While animated, it frequently hap- 
pens that the whole are not fhewn at all during 
the time of animation, or difplayed very flowly.
