86 ANALYSIS AND ADULTERATIONS OF BUTTER. 



It will be observed that Mr. Estcourt takes the specific 

 gravities at a temperature approaching as nearly as possible 

 that of boiling water. He places, however, but little reliance 

 upon the specific gravity test, for he advises, " as the best 

 practical method of estimating fairly the percentage of adul- 

 teration, that after the gravity has been obtained, the fatty 

 acid determination be made," especially in cases which may 

 result in legal proceedings against the vendor.
