As regards the use of tho eucalyptus In
shipbuilding. we learn from Australian news
papers that vessels constructed Of this timber
are Of extreme solilty. wcmav add that masts
hundred and twenty feet in length are easily
procured. Being saturated with balsamic and

TO resist decay, and for the same reason. is sol

Of which this tree has been the object and the
therapeutic value Of it, products. According to
a memoir presented to the French Academy Of
Sciences. the essence furnished by the cucalyp-
tus is n species Of liquid camphor. The auuc-
Gus infusion OF the leaves possesses uncommon
astringent qualities. due to the presence Of II

the infusion have been found singularly cflica-

have been tested on a great scale in Austria and
Roumania and Spain. and especially by Dr..
Brunei in Monteyidco. 1t appears from his
clinical observations. covering a series Of years.
