OFFICIAL INSPECTION 14. I37 



bottle containing a mixture of cane and maple, the fact that the bottle 

 is correctly labeled does not protect the dealer from prosecution for 

 adulteration. It even makes the case against him stronger. For he has 

 knowingly, as evidenced by the label, sold an imitation for the real. 

 If a customer asks for molasses and the dealer fills the jug with a 

 mixture of glucose and molasses, putting a label on the jug that it is 

 compound molasses, in no wise lessens the sale of adulterated goods. 

 It is perfectly lawful to sell these goods for just what they are but they 

 cannot be lawfully substituted for the article they imitate.

SPIRIT OF NITROUS ETHER. 



(Sweet Spirit of Nitre.) 



The following precautions in handling concentrated nitrous ether, 

 preparing, keeping and dispensing the spirit of nitrous ether, if observed, 

 should prevent undue deterioration and if they are followed in every 

 respect, druggists will not be prosecuted under the Maine Food and 

 Drug Law if on analysis the spirit of nitrous ether dispensed should 

 yield "less than 4 per cent ethyl nitrite." 



Spirit of nitrous ether may be prepared according to the U. S. P. 

 Eighth Edition or may be made from concentrated nitrous ether. 

 If the latter method is used purchase concentrated nitrous ether from 

 a reliable house. If the label does not carry the U. S. serial number, 

 obtain a written guaranty from the seller as to its strength. 



Buy in small sealed packages so that the spirit of nitrous ether made 

 therefrom will under ordinary conditions be sold inside of one month. 



Follow directions for preparation as given by the manufacturer as 

 regards the proportions of concentrated nitrous ether and alcohol to be 

 used. Thoroughly chill both the concentrated nitrous ether and the 

 alcohol. Use a towel or other non-conducting material in handling the 

 concentrated nitrous ether container. Do not pour through the air 

 more than absolutely necessary. 



Store in amber colored, glass bottle, stoppered with tight fitting cork 

 stopper. Do not use a ground glass stopper. 



Keep the bottle in a cool place. Room temperature is not cool enough. 



Put the date of manufacture on the bottle. 



Do not sell after six weeks from preparation without testing strength 

 by assay. If weak bring up 10 strength by adding concentrated nitrous 

 ether q. s. and put new date on bottle. 



Put date of manufacture on bottle given to customer. 



A cautionary statement on the label of the dispensing bottle advising 

 the customer of the volatile nature of sweet spirit of nitre and that it 

 should be kept tightly stoppered in a cool place and not used more than 

 12 weeks after date of manufacture is suggested. 



All persons retailing sweet spirit of nitrous ether in bottles as put up 

 by manufacturers should buy these goods under special guaranty as to 

 date of their manufacture, their being of U. S. P. strength, and length 

 of time which they are guaranteed to remain U. S. P. strength. At 

 expiration of this time, they should be withdrawn from sale.
