 that the chemical composition be stated in a manner analogous t 

 that used in the Green Tables. This procedure was necessary i 

 order to reduce the terminology to a common and nonequivocal basii 

 Out of the 13 makers, or their accredited sole importers or sellin 

 agents in the United States, who were consulted, 9 have supplied th 

 specimens requested; the remaining 4 promised to contribute, bu 

 have not done so. In the following table is shown the amount an) 

 character of the information obtained: 



Tabulation of distribution of replies and character of information received. 



In order to make provision for the 24 makers listed in the Gree) 

 Tables and not included in the 13 makers addressed requests fo 

 samples were sent to two domestic houses which import coal-tar color 

 from scources other than the above, for use in food products; thei 

 products must fairly represent any of the colors not covered by thl 

 13 makers addressed. Of these two importers, one responded wit] 

 13 samples, and of each he gave the number in the Green Table 

 corresponding to each specimen ; the other importer has not redeeme- 

 his promise to contribute specimens. 



A third importer volunteered the Green Table numbers of four ou 

 of five coal-tar colors used in his business, but could not even approx 

 imately say what the remaining color was chemically. He did no 

 contribute any specimens, nor was that necessary at the time thi 

 information was volunteered. 



A fourth importer contributed specimens of five coal-tar color 

 needed in his business, but was able to give Green Table numbers fo 

 only three of them ; he could not give even approximately the chem 

 ical composition of the remaining two. 



Out of the 17 responsible concerns consulted 5, or 29 percent, have no 

 found it to their interest to contribute either specimens or information
