six cells, and these open into one common excretory duct. In 

 the casuarius emu the solvent glands are oval bags i-tn ot an inch 

 lone and -Uh of an inch wide. They occupy the whole sur- 

 face of the' cardiac cavity, which is very large. The gizzard is si- 

 tuated out of the direction of the cardiac cavity, so that the food 

 can pass into the duodenum without entering the gizzard, lne 

 structure of these organs in the long-legged cassowary ot New 

 South Wales is similar. Sir Everard Home terminates his 

 paper by showing that the length of the intestines m birds in- 

 creases with the scarcity of their food. 



In the Casuarius Emu the intestines are 7 feet long. 



Rhea Americana 19 feet 1 1 inches. 



Struthio Camelus 77 feet 9 inches. 



X. Additional Remarks on the State in ivhch Alcohol exists 

 in Fermented Liquors. By William Thomas Brande, Esq. 

 E R S 1 To confirm his former conclusions respecting the great 

 quantity of alcohol contained in wine, Mr. Brander had recourse 

 to the following process. He dropped into the wine a solution 

 of acetate of lead (Goulard's extract) till the whole colouring 

 matter was precipitated. The wine thus freed from colouring 

 matter was mixed with dry subcarbonate of potash, and set aside. 

 \lcohol soon separated, and floated on the surface of the liquid. 

 The quantity of alcohol thus obtained agreed with his former 

 experiments nearly. He found that when Port wine was partly 

 distilled, the portion in the receiver being mixed with that in the 

 alembic, the wine was restored to its original taste and specific 

 gravity. Mr. Brande now states the quantity of alcohol ol 0-825 

 in 100 measures of Port wine at 22 measures. _ 



XI. On a new Variety in the Breeds of Sheep. By Colonel 

 David Humpries, F.R.S.] Seth Wight, who possessed a small 

 farm on the Charles River, about 16 miles from Boston, had a 

 small flock, consisting of 15 ewes and one ram. One of these 

 ewes in 1 791 produced a singular shaped lamb. He was advised 

 to kill his former ram, and keep this new one in place of it: the 

 consequence was, the formation of a new breed of sheep, which 

 graduallv spread over a considerable part of New England : but 

 The introduction of the merinos has nearly destroyed them again. 

 This new variety was called the otter or ankon breed. They are 

 remarkable for the shortness of their legs, and the crookedness 

 of their lore leys, like an elbow. They are much feebler, and 

 much smaller, than the common sheep, and less able to break 

 over low fences. This was the reason of their being continued 

 and propagated.
