PHENACETIN. 



45 



A general registered trade-mark, No. 31422, consisting of the figure 

 of a winged lion resting one forepaw on a globe whilr th<> otlnr j>a\v 

 grasps a caduceus, is also found on each package. 



The cartons of the irregular product arc plainly marked a^ i> the 

 manufacturer and source of production. Each package U l:il>clcd in 

 English, French, and German as follows: 



1 'Patented in the United States of America, Nr. 400086. Phenace- 

 tine-Bayer. The resale and importation to the United States of America 

 are prohibited." 



The sample purchased by its chemical name bore the following 

 label: 



"1 Ib. Paracetphenetidine Powder B. P. This serves to remind that 

 this article must not be sold to the United States, it being patented in 

 that country. Made in Germany. E. Merck. Darmstadt." 



ANALYTICAL RESULTS. 



The tests applied to these samples were such as have been found 

 of service in establishing the quality of phenacetin, and include phy^- 

 ical appearance, melting point, solubility, and the presence of 

 p-phenetidin. 



Analyses of commercial samples of phenacetin. 



n Began to soften at 94 C. 



All of these samples are of satisfactory quality except No. 845388, 

 which is a mixture of phenacetin and acetanilid, containing about 20 

 per cent of the latter. This sample and the paracetphenidin were 

 purchased at the same place, while the other unauthorized sample 

 was obtained from a different source of supply. On examining the 

 carton containing the mixture of phenacetin and acetanilid it appeared 

 to be spurious. The two empty cartons containing the unauthorized 

 phenacetin were sent to the patentee's agent in New York with the 

 request that he express an opinion as to their genuineness. These 

 packages were immediately returned, No. 845388 being marked coun- 

 terfeit, the other genuine. The bogus carton resembled the genuine 

 one very closely, though there was a difference in color, style of type, 

 and the ornamental lines employed.
