JUNIPERINE. 
BY J. H. SALISBURY. 
In January of 1847, after having obtained a peculiar chrys- 
talizable principle* from the outside bark of the white birch 
(betula populifolia), and while examining for similar princi- 
ples in the hemlock (pinus Canadensis), black birch (betula len- 
ta), red cedar (juniperus Virginiana), and several other species, 
tufts of acicular crystals were observed shooting out from the wood 
of the red cedar, which, on further examination, seemed to con- 
duct themselves, in many respects, very similar to those of the 
white birch. This body, at that time, was supposed to be new. 
It has since been obtained in considerable quantities, and the ex- 
aminations which have been made seem to confirm the former 
opinion. It may, however, turn out to be nothing more than the 
solid essence of the plant noticed before by others, though the man- 
ner of obtaining it is very different. There is so little said of the 
solid essence of cedar wood, that it is difficult to decide yet 
whether it be the same substance or not. 
The liberty has been taken, till other examinations be made 
which are now under way, to call it Juniperine. 
It is extremely volatile, passing off at the ordinary temperature 
of the atmosphere. It smells strongly of the hejirt wood of the 
red cedar, and seems to be the principle to which it owe's its agree- 
able and fragrant odor. 
When sublimed from the wood, it crystalizes in beautiful fas- 
ciculated tufts. These recrystalized from ether, often take a stel- 
lated arrangement, and from oil of turpentine a pinnate. Some 
of the crystals, under favorable circumstances, when the process 
is continued for a considerable length of time, at a proper tem- 
perature, are occasionally extended from one to two inches in 
length. 
• The crystals observed in the bark of the white birch may be beUiline, notice" 
first by Lowry. A method of obtainin<T tliem was noticed by Prof. Emmons, in 
the January No. of 1847, of his Journal of Apricullure and Science.
