From 1894 to 1898 corn oil was subjected to much study, reports 

 on its physical constants being published by Hehner and Mitchell 

 (15), Duliere (9), and Hehner (14). In 1898 Hopkins (19) made 

 an extensive stud} 7 of the oil and Procter (3 If.) reported on its plrysical 

 constants and Wiley and Bigelow (54) determined the calories of 

 the oil. 



In 1899 Winfield (55) published a monograph, including a review 

 of the literature and the results of her study of the oil. At about 

 the same time Archbutt (3) reported the oil as semidrying and un- 

 suitable for lubricating purposes. The following year Morpurgo 

 and Gotzl (29) found that corn oil is difficult to detect in cottonseed 

 oil and in 1901 Vulte and Gibson (51) determined the constants of the 

 oil and claimed to have confirmed the presence of hypogaeic, arachidic, 

 acetic, and formic acids. In 1903 a comparison of olive oil with corn 

 oil was made by Tolman and Munson (50), and Moore (28) studied 

 the digestibility of the oil. In the same year Gill and Tufts (10) 

 suggested that the presence of sitosterol in corn oil might serve as a 

 means of identifying it when present in other oils. The same au- 

 thors (11) also published during the year their investigation of the 

 unsaponifiable matter. The possibility of corn oil being used as an 

 adulterant in lard was investigated by McPherson and Ruth (26) 

 in 1906. Two years later Ritter (36) claims to have found the oil 

 equal to olive or cod-liver oil in the treatment of tuberculosis. 



In 1909 Wagner (52) published an account of the development of 

 the corn-products industry, in which he refers to some of the tech- 

 nical uses of corn oil and Olig and Brust (32) reported on the con- 

 stants of nine samples of corn oil. The refractive index of the oil 

 received the attention of Klimont (22) in 1911 and Smith (4-7) in 

 1912. The following year an editorial (1) in the Seifensieder-Zei- 

 tung suggested the use of the oil for edible purposes and Pool and 

 Sayre (33) studied the oil with a view toward its substitution for 

 olive and cottonseed oils in pharmaceutical preparations. In 1915 

 the constants were again reported on by Backer (4) and Sayre (39) 

 found its drying properties to be greatly inferior to linseed oil. 



The adaptability of corn oil to cooking and baking and for gen- 

 eral edible purposes was pointed out by Sayre (40) in 1916. The 

 digestibility of corn oil was found to be similar to that of cottonseed 

 oil and somewhat greater than that of lard by Rockwood and Sivickes 

 (37) in 1918, and in the same year Holmes (17) found the oil to be 

 digestible and suitable for food purposes. The following year Holt, 

 Courtney, and Fales (18) also reported favorably on the digestibility 

 of the oil and its food value. In 1920 Rabak (35) studied the effect 

 of mold on the composition of corn oil and reported that the mold 

 apparently feeds on the oil, causing the latter to disappear gradu-
