The specilic iiTavilv. ret'ractive index, rise of temperature with 

 sulphuric acid, and saponilicat ion number of this oil arc practically 

 identical with the same values of olive oils. The iodin number is much 

 lower, and the melting point of fatty acids much higher than for olive 

 oils. lnit when mixed, for example, with an olive oil having a liijrh 

 iodin numher and a consequently low melting point for its fatty acids 

 as much as ;.< to <!<> per cent of the lard oil could he u-ed without ren- 

 dering these values abnormal for pure oils. 'The lard oils have a liijjli 

 contour of solid fatty acids, hut this factor is rendered of little value 

 when the oil is mixed with an olive oil having a hi.irh iodin number, 

 since such an olive oil will probably have a correspondingly low con- 

 tent of solid fatt acids as is shown b Table XXXIII. 



The oils named in tables XXXII and XXXIII were analyzed* to 



obtain further data regarding their values, and also for the purpose of 

 studying their use in the adulteration of olive oil. Through tho. 

 kindness of the V. I). Anderson Company, of Cleveland, a number of 

 cold-pressed oils were prepared from seeds which were identified in 

 the seed laboratory of the Department of Agriculture. They are as 

 follows: 



Hrmvn mu.-tard ......................... Brassica arrewls (charlock). 



P.lack mustard ......................... Brassica juncea (Indian mustard). 



Yellow mustard ........................ Sinapis alba (yellow mustard). 



Rape .................................. />w.s-.s-/m. IKI/HI*. 



Poppy ................................. J'o/Hiri'r xoinnift'ro (opium poppy). 



The cocoanut oil was prosed from the flesh of cocoanuts. The pea- 

 nuts used were from Virginia. The almond, cotton-seed, and lin-. <-d 

 oils were prepared from commercial seed. Other oils were prepared" 



in the laboratory. 



There are a number of commercial oils included in these tables, but 

 as there was no way of being assured of their purity the results obtained 

 are not of great value. Sample No. ^lUior, was sent by Armour & Co. 

 as a pure neutral lard oil and it had practically no lard odor or ta-te 

 except when heated. These samples were discussed under the headings 

 of the various oils.
