Annual wool review, J. B. McPhkrson (Bui. \at. Assoc. Wool Manfrx., 38 

 (l!l(iS). Ao. 'i. lip. S.')3-3!)6, chart /). — A review of the wool iiulustry for I'.tOS 

 with imicli statistical matter. In New Mexico and Arizona the iuuiil)er of sheep 

 lit for shearing increasetl duriiij: the year. The price of wool was 1.5 per cent 

 lower zhaii in 11)07. A stora.ue warehonse was bnilt at Omaha, where l.OOO.OOO 

 lbs. of wool was stored until the market partially recovered. A movement is on 

 foot to establish a jtermanent storasje warehouse in the Central West, where 

 wool can be stored and sold directly to the manufacturer. 



On digestion of meat in the stomach, and small intestine of swine, E.

 which all fat hi.d been removed, was ground, cooked for 1 hour, and washed 

 until. the wash water showed no biuret reaction. Six swine were fed 500 gm. 

 each of this meat, and the protein metabolism was studied by post-mortem 

 examinations of the stomachs and small intestines. In all cases 2 hours after 

 feeding time there was an acid reaction in all parts of the stomach, though from 

 i to 1 hour after the feeding period near the opening of the esophagus the 

 reaction was alkalin. Chemical analyses were made of different portions of 

 the stomach. After I hour digestion, cleavage products of protein were found 

 in all portions. 



The following table shows the cleavage products of the mixed contents in 

 the stomach at different periods:
