76 American Elks. — A New Instrument for Cataract.

THE SPINAL MARROW. 



Dr.Tiedemann (of America) endeavours to demonstrate, that 

 instead of the spinal marrow being a continuation or prolon- 

 gation of the brain, it is the latter and the cerebellum to boot, 

 which proceed from the spinal marrow ; alias, that the brain 

 and cerebellum are an ejfflorescence of the marrow in question. 



AMERICAN ELKS. 



A description of the animal was read not long since at the 

 Linnean Society. It is also figured in Fred. Cuvier's work 

 now publishing in numbers. There is also a figure and some 

 account of it in an early number of the Colonial Journal. 



A pair of the beautiful and gigantic non-descript Elks, known 

 by the Indians of the Upper Missouri (where they have been 

 lately discovered) by the name of Wappeti, arrived at Liver- 

 pool on Tuesday the 9th of July, on their way to London. 

 These noble animals are the size of the horse with immense 

 spreading horns ; their form the most perfect model of strength 

 and beauty, combining the muscular strength of the race-horse, 

 with the lightness and agility of the greyhound ; are capable 

 with ease of drawing a carriage or carrying a person more than 

 20 miles an hour. They are perfectly domesticated, and of 

 the most amiable and gentle disposition. — Liverpool Advertiser. 



A NEW INSTRUMENT FOR CATARACT. 



Professor Gibson, of the University of Pennsylvania, has 

 lately invented an instrument exceedingly well calculated for 

 cutting to pieces the crystalline lens, in all cases of cataract. 

 It is well known that the knives of Saunders, Sir William 

 Adams, and other oculists, are defective, in not being suffici- 

 ently strong and sharp to divide the lens when it happens to 

 be of a very hard texture. Under such circumstances, the 

 cataract is soon dislocated, in the attempt to divide it by the 

 knite ; and is either depressed into the vitreous humour, or else 

 enucleated from its capsule. To obviate these inconveniences, 

 Dr. Gibson has contrived a scissor so delicate, as hardly to 

 exceed in size the iris knife of Sir William Adams, and, at 

 the same time, so strong and sharp, as to cut, vith ease, the 

 most solid and compact lens and capsule, without injuring in 

 the >ilighlest dcgrct- any jiart of the eye. These scissors are
