ZOOLOGY. 
1. Calcareous Coverings of Polypi .—The observations of Dr. Milne Edwards 
on the Polypi of the Mediterranean, have induced him to conclude that the 
horny, cartilaginous or calcareous coverings which envelop them, far from being 
merely external crusts, without any organic connexion with the animals which 
produce them, are integrant parts of these beings, and consist of an organized 
tissue, the substance of which is more or less charged with horny or calcareous 
matter deposited in it; and the nutrition of which is effected by introsusception. 
Among all these animals there exists a tendency in their tegumentary and 
reproductive parts to become hard, and the degree of solidification which these 
parts attain, is the only character by which zoologists can class them, as naked 
Polyps, flexible Polyps, &c. Thus the cartilaginous or stony covering of a 
Sertidaria , or Zoaniharia , is not a dwelling constructed for themselves by these 
animals, but a skin which forms a solid frame-work of their body; and which, 
like the skin of vertebrated animals, sometimes affects a membranous form, at 
others a cartilaginous texture, and even a condition which may be called bony. 
2. Death of a tame Elephant in Paris. —“ Asie,” the male Elephant in the 
Jardin des Plantes, died on Saturday, March 23, after an illness of ten days. 
The chief remedy administered was honey dissolved in water, given in homoeopathic 
doses of about ten-pails-full at a time, sometimes with the addition of sulphate 
of soda. The only person who could induce him to take his medicine was Gean
