COR R.E SPONDENCE. 
THE SEA-SERPENT. 
To the Editor of the Monthly Journal of Science . 
Sir, — With reference to the letter of “ Serpent-Hunter,” in your 
February No., I would beg to ask whether anyone has taken the 
taken the trouble to ascertain whether any such narrative as that 
quoted in Dr. Wilson’s work was really deposed to at Liverpool, 
or whether the whole is not the invention of some audacious 
canard-monger ? A friend tells me that this point has been 
raised by one of your contemporaries. — I am, &c., 
Sceptic. 
SPIDER’S WEB FOR MICROMETERS. 
To the Editor of the Monthly Journal of Science. 
Sir, — Mr. W. Mattieu Williams, in his article on “ Spider’s Web 
for Micrometers,” contained in your last issue, speaks of spiders 
as “ his six-legged friends.” This is doubtless a clerical error, 
as spiders have eight legs. — I am, &c., 
An Entomologist. 
ADHEMAR’S THEORY OF EVOLUTION. 
To the Editor of the Monthly Journal of Science. 
Sir, — Has the possible bearing of Adhemar’s theory upon the 
question of Evolution ever been thoroughly discussed ? If 
every ten thousand years the waters of the globe are translated 
from the Northern to the Southern Hemisphere, deluging the 
continents on their way, must not the great majority of animal 
and vegetable species, terrestrial at least, be extirpated ? If 
prior to the last of these great cataclysms the bulk of the water 
occupied the Northern Hemisphere, where were the wide conti- 
nents in which the majority of organic species seem to have 
taken their rise ?
