LISTS OF COLORS RECOMMENDED BY INDIVIDUALS. 177 



UNPUBLISHED RECOMMENDATIONS OF A MANUFACTURER. 



In addition to these published recommended lists the folio whig 

 recommendation has been made by letter by a manufacturer who 

 contributed specimens of food colors to the United States market 

 in the summer of 1907: 



That for the f ollowing permitted colors of Food Inspection Decision 

 No. 76, there be substituted certain colors, the Green Table numbers 

 alone being here given : 



Permitted. Substitute. 



4 94 



56 53 



85 15 



517 521 



In regard to these proposed substitutes it is to be said that Nos. 

 15 and 521 were not on the United States market in the summer of 

 1907, according to the canvass made and described in Section I, 

 Nos. 53 and 94 were on that market, No. 53 had not been examined 

 physiologically, and No. 94 had been examined physiologically 

 with only unfavorable results. The way was, therefore, not open to 

 placing any of these colors on the permitted list under the procedure 

 adopted. However, had No. 15 been on the market it would not 

 have been placed on the permitted list, because it has been examined 

 physiologically with contradictory results, while No. 521 might have 

 been placed on the permitted list because it seems to have been 

 examined physiologically and with only favorable results. 



BEHAL. 



As the result of careful investigation Belial (Revue Generate des 

 Matieres Colorantes, 1910, p. 131) suggests the use of 21 definite 

 chemical individuals which are given hi the following. With the 

 tabulation on page 63 as a guide these 21 colors are classified as 

 unfavorable, favorable, contradictory, and not reported on. The
