METHOD oF PuTTING PELAGIC ANIMALS TO SLEEP IN ORDER TO 
OBTAIN THEIR PHorocrapns.—Dr. Fol,? of Geneva, has made the 
important discovery that Ccelenterates and Echinoderms may be 
rendered insensible and kept so for hours and even days, witne 
injury, by saturating the water with carbonic acid. i 
taining vessel must, of course, be hermetically closed. pecs 
mal at once becomes insensible and motionless, but preserves £

life-like photographs, but also, as Dr. Fol suggests, 
ing animals alive. Fishes and mollusks do no 
ment, and crustaceans for only a short time. 
Dr. Fol tried various narcotics, but found that S$ 
would not bring the animals to rest, while large doses ac 
poisons. The same proved true of tobacco smoke d aque 
solutions of ether, chloroform and ethyl bromide. Sulphy: cal
