mixture of lime water, solution of zinc chloride and mercuric 

 chloride, was white if they were mixed in the above order, and 

 yellow if the mercuric chloride was first added to lime water. 



What is the proper color of fluid extract of corn silk? was a 

 question discussed by Messrs. Lascoff, Boehrig, Lohmann, Muir, 

 Dissosway and Raubenheimer. It was the general opinion that a 

 light-colored product could not be prepared according to the N. F. 

 process, and that if a freshly gathered silk was to be used the prep- 

 aration should be included among the tinctures of fresh herbs.

FOOD INSPECTION DECISION 103. 



The Labeling of Turpentine. 



The Department has received a number of letters with reference 

 to the proper labeling of the product generally known as "wood 

 turpentine," etc., obtained by steam distilling or destructively dis- 

 tilling woods. Food Inspection Decision 58 recognizes that — 



Products used in the arts and for technical purposes are not sub- 

 ject to the Food and Drugs Act * * * when plainly marked 

 so as to indicate that they are not to be employed for food or me- 

 dicinal purposes. 



It is held, therefore, that when wood turpentine is labeled, "Not 

 for Medicinal LTse," etc., it is not subject to the food and drugs act. 

 When not so labeled it is in violation of section 7 of the food and 

 drugs act unless labeled "wood" or "stump" turpentine. Articles 

 labeled "turpentine," "spirits of turpentine," or "gum turpentine," 

 etc., must comply with pharmacopoeial requirements ; that is, they 

 must be light oils of certain properties made by distilling the 

 oleoresin of various species of Finns. The word "wood" or "stump" 

 should be in the same type and on the same background as the 

 word "turpentine," thus being given equal prominence.
