From 1894 to 1898 corn oil was subjected to much study, reports 
on its physical constants being published by Hehner and Mitchell 
(Id), Duliere (9). and Hehner (U). In 1898 Hopkins (19) made 
an extensive study of the oil and Procter (3S) reported on its physical 
constants and Wiley and Bigelow (54) determined the calories of 
the oil. 
In 1899 \Yinfleld (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-dimcult 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 hypoga?ic. 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 (47) 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 (4-0) 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 Rock wood 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 hitter to disappear gradu-
