by mechanical agitation, and by the growth of sea-weeds on 

 the rocks. The animals at present in the aquarium are sea 

 anemones (about twelve species and 3000 individuals), tube- 

 worms (four species), star fishes (three species), sea urchins, 

 lobsters, crawfish, edible crabs, spider-crabs, swimming crabs, 

 and various other crabs, prawn (two species), barnacles, oys- 

 ters, mussels, cockles, scallops, whelks, periwinkles, dogwin- 

 kles, topes, cuttles (two species), skates, angel fish, lunce, pipe- 

 fish, lumpfish, sucking fish, sole, plaice, cod, whiting pout, 

 whiting, rockling, wrasse (four species), goby (three species), 

 blenny (three species), dragonet, gunnel, gray mullet, sea 

 bream, sea scorpion (two species), pogge, gurnard, weaver, 

 bass, and many other species of fish. A few of the animals 

 consume green sea-weed, but the food of by far the larger 

 number is animal, consisting of shrimps (alive or dead), crabs, 

 mussels, oysters, and fish, but never butcher-meat. A full 

 and very interesting account of this magnificent object, with 

 drawings, appears in Nature for October 12. 



- ILLUSTRATION OF PSYCHIC FORCE. 



A correspondent of Les 3fondes y writing in reference to the 

 communications which have appeared in regard to the " psy- 

 chic force," narrates a curious fact as coming within his own 

 experience. He states that a favorite dog had been in the 

 habit of taking up his abode upon a skin of a white bear in 

 his master's chamber. On one occasion, while the dog was 

 reclining upon the skin, the writer looking at him and admir- 

 ing the entire confidence with which he rested his head upon 

 the skin of this polar monster, the thought suddenly came 

 into his mind as to the effect that would be produced upon 

 the dog if it were a real bear, and not a mere skin. In a 

 flash the dog gave a sudden bound, and got as far off the 

 skin as possible, his ears erect and hair standing on end, with 

 his mouth open, and exhibiting the utmost anxiety and terror. 

 It was a long time before the animal could be induced to ap- 

 proach the skin and recline upon it as before, several days 

 elapsing before this could be brought about ! 3 13, xxv., Au-
