seen, but none caught; they were often observed to make very high 

 though clumsy leajjs, a feat not often I believe practised by flat fish. 

 A fish of considerable size, from twelve to twenty lbs. weight appa- 

 rently, and in form resembling the salmon, was frequently seen of an 

 evening performing very astonishing leaps. They were always quite 

 perpendicular, and therefore appeared as a gambol, more than an effort 

 to take prey, and sometimes extended to a height of thirt}^ feet. 



Of shell-fish we found craw-fish and prawns, the latter of great 

 size and very delicious ; they are limited to the creeks of the east 

 side of the island, where also the one in the neighbourhood of the 

 Meug-breng village possesses truly fine oysters. They are large, 

 but of a flavour as delicate as our own Colchester luxury : it may 

 be lamented that they are not more generally known, and attempts 

 made to grow them elsewhere. They have been transported to Kyouk 

 Phyoo, and do well there. 



Turtle are common, and are taken by the natives on the sand- 

 islands and bays. They are of large size and of good species, but I 

 can make no mention of their quality as food. 



Many beautiful and valuable species of shells are to be found on 

 the fiats off the North Point of the island, where however but little 

 leisure or opportunity of dredging for them was afforded. 



Of wild birds, theSarus [Larus.H is perhaps the largest on the island, 

 and is plentiful. They are common in other parts of India, and are, I 

 believe, good eating. There are a great many varieties of the crane, 

 some of very beautiful plumage and great size. These constitute 

 the greatest portion of the feathered inhabitants, and would supply 

 perhaps some new and valuable varieties, if not species : doves are 

 very numerous ; a small green parrot is found, and some few green 

 pigeons were seen. But in general, other than have been mentioned, 

 the birds are of those species most commonly met with in these cli- 

 mates. The jungles are, however, scantily peopled, though I may 

 not omit to notice one which, with its sweet and soft note late in 

 the evening, often gratified us, and was deemed not an unworthy 

 brother-songster of the nightingale. 



NIGER EXPEDITION : — DR. VOGEL. 



Our readers will rejoice to learn that Dr. Vogel, Mr. Fraser, and 

 Dr. Stanger are not among the victims of the fatal Niger expedition. 

 Dr. Vogel has recovered from an attack of fever, and will remain for 

 a time at Fernando Po, for the purpose of botanical investigation.

On the Structure of the Cyst-worm. By George Gulliver, F.R.S. 

 (Medico-Chir. Trans., vol. xxiv.) 



Ix this memoir, after remarking the great importance of the Cyst- 

 worm as one of the very few parasites that infest the muscular fibre 

 of man, as well as that of animals used by him as food, the author 

 proceeds to describe many points in the anatomy of the Entozoon
