In the extract of beef, or in the isolated juice of 

 beef, are found enormous quantities of minerals in 

 a perfectly assimilable condition. In one hundred 

 pounds of good dry extract of beef, made by evap- 

 orating the juices, there are contained twenty-one 

 pounds of the most important agents needed in the 

 animal economy. We would suggest to physicians 

 and invalids the use of this beef extract in all cases 

 where the system is suffering from deficient nutri- 

 tion, or where there is any weakening of the vital 

 powers through an insufficient supply of the mineral 

 c r nutritive agents essential to perfect health.
