some centuries. Rurnpli^ already 200 years ago,

remedy especially as administered somewhile after 
parturition ; he also found the native people 
there employing the foliage of the Cajuputi- 
Melaleuca as an insecticide. In legitimate practice 
the oil has long been recognized as an anti-spas- 
modic. 
Professor Schulz in his first chapter explains 
that the Eucalyptus Oils, as they appear in com- 
merce, differ considerably ; this is traceable partly 
to the diversity of the raw material, partly to the 
mode of distillation, and partly to the age of the 
oil. He operated with oil distilled from leaves of 
Eucalyptus Globulus obtained from Algeria. 
There this tree for forestral and hygienic pur- 
poses was introduced and also largely diffused 
chiefly through the writer of this communication. 
That oil, however, which on by far the largest scale 
is exported from Mr. Bosisto’s great factory to 
almost all parts of the world, is derived from the 
richly yielding Eucalyptus amygdalina, first 
brought under notice by the writer as the cheapest 
of all Eucalyptus oils. In reference to various 
oils from different species of Eucalypts, the re- 
ports of the International Exhibitions of 1855, 
1862, and of subsequent years might be consulted, 
furthermore, the descriptive Atlas of Eucalypts,
