PREFATORY NOTICE. 
sinineniewiliesnaetini 
To those who have noticed my various publications fit will have been 
observed how anxious I am to record all that is known relative to 
the economic and medicinal properties of the plants brought under 
my notice as well as their botanic distinctions. My pleasure may 
then be in a small degree imagined at the great kindness of my 
esteemed friend, Dr. Joseph Lauterer, in placing in my hands, for 
Publication in one of these Botany Bulletins, the present valuable 
notices of the chemical and medicinal properties of so large a number 
of our indigenous gums and resins. The samples from which the 
Tesults have been obtained were in a great many instances taken from 
exhibits in the Museum of Economie Botany ; therefore, I can with 
confidence vouch for their authenticity. The want of such a publi- 
cation has long been felt by artisans who use the several products 
herein mentioned, and I feel confident they will fully appreciate the 
many long hours spent by Dr. Lauterer in working out by original 
research the careful details regarding the gums and resins of the trees 
brought under notice, and hope with me that he will continue his 
"searches and allow the results of his labours to be published in this 
I take the present opportunity of expressing my thanks to 
those persons who have kindly forwarded to me samples of gums and 
Anas of the native trees from the various parts of our extensive 
territory, and hope that as opportunities occur they will continue 
their aid in this good work.
