 G., E. — Gum Tragacanth. 



[The best material for sticking labels to glass. As it will not dissolve in 

 water like gum arabic, some find difficulty in preparing it. The best way 

 is to select three or four white pieces, about the size of a coffee-berry, and 

 place in a 2-oz. wide-mouthed bottle ; then pour over it acetic acid so as 

 to hardly cover the gum, and place the bottle aside until the next day, 

 by which time the gum will have absorbed the fluid and become very 

 much swollen. Now add water, stir well, and in a day or two a semi- 

 transparent jelly will be the result. A drop or two of pure carbolic acid 

 should be added, and it will then keep for any length of time without 

 getting mouldy.]
