"QUADRUPED" DREDGED BY THE AUSTRALIAN ECLIPSE 



EXPEDITION. 



The remarkable announcement is made by a member of 

 the Australian Eclipse Expedition that the party dredged up 

 an animal on a piece of coral, the body of which was that of 

 a fish, but which had, instead of fins, four legs, terminated 

 with so-called hands. The fish, somewhat resembling a liz- 

 ard, stood up on its four legs when placed on the skylight 

 of the steamer! 12 A^June 20,1872,150. 



WORMS IN THE TROUT OF THE YELLOWSTONE LAKE. 



In referring to the explorations of Dr. Hayden about the 

 Yellowstone Lake during the past summer, mention was 

 made of the fact that the trout all seemed very much infest- 

 ed with a peculiar kind of worm, which interfered considera- 

 bly with the enjoyment of eating them. Specimens of this 

 animal have been submitted to Professor Leidy, of Philadel- 

 phia, who reports that they represent a new species or type 

 of worm, of the genus Dibothrium. Two species of the genus 

 have long been known as infesting salmon and other mem- 

 bers of the trout family in Europe, but both are decidedly 

 different from the new form just mentioned. MSS. 



RESTORATION OF EXCISED BRAIN IN PIGEONS. 



Fifty years ago Mr. Flourens removed the brains of cats 

 and rabbits, and demonstrated that these animals could live 

 without them. Recently Mr.Voit, of Munich, has obtained 

 still more remarkable results. On several occasions he re- 

 moved the brain of a pigeon, and found, to his astonishment, 

 that after some months it had grown again. The learned 

 physiologist says that for some weeks after the operation the 

 birds seem to sleep, with their heads under the wings, after 

 which they open their eyes and commence to fly about. They 

 do not strike against any obstacle, and skillfully avoid being 

 caught. This shows that they can both see and hear. When 

 some of the animals were killed, five months after the opera- 

 tion, the cavity of the skull was filled with brain matter in 

 two lobes, between which a dividing membrane (septum) was 

 found. 3 C, November 16,1872.
