LARD AND LAUD ADULTERATIONS. 497 



NOTES TO TABLES Nos. 23, 24, AND 25. 



In Table 23 arc included all tlic lord's of a miscellaneous origin 

 which have been examined by us, and which could not be properly 

 classified under any of the preceding heads. Of these quite a number 

 deport themselves with re-agents as pure hog grease, while others are 

 without doubt adulterated. Of those which appear pure! will mention 

 Nos. 5551, 5GG7, and 56G9. 



The microscope revealed the presence of beef fat in most of the other 

 samples, while other tests confirmed the presence of adulterants. 



In Table 24 are collected the data obtained by the analyses of crude 

 cotton oils and foots or tank settlings. 



Nos. G03 and 5G04 were furnished as pure cotton oils, but the analy- 

 ses showed that they were heavily adulterated. These are the only in- 

 stances in which crude or refined cotton oils were found to be adulter- 

 ated. The nature of the adulterant was not determined. 



Table No. 25 contains the analyses of miscellaneous oils, and espe- 

 cially of dead-hoggrease. 



The low specific gravity of the lard oil (No. 5G21) appears anomalous, 

 since it should be higher than pure lard. Further investigations will 

 determine the normal density of lard oil at any given temperature. 

 Pea-nut oil (No. 5622) has practically the same specific gravity as cotton 

 oil; while olive and rape seed oils have densities slightly above [mre 

 lard. Dead-hog lard differs from the pure variety chiefly in its refract- 

 ive index and the quantity of free acid it contains.
