ETJCALTPTUS GLOBULUS. 



The statements in reference to the specific gravity hitherto given fluctuate between 

 (Osborne) and 1"108 (Laslett). This great disparity finds its explanation in the different degrees 

 of dryness (natural or artificial) and also in the age and quality of the timber from different 

 localities. To render records of this kind most reliable, the mean of a multitude of observations 

 should be ascertained, and the samples be reduced to an uniform complete dryness. Our experi- 

 ments here on ordinary samples from timber yards ranged in their results from -845 to 1"096. 



Perhaps not even to the Royal Oak of England has such an extensive literature been devoted at 

 any particular period as to our Blue Gum-tree within the last twenty years. Indeed, if even only the 

 main substance of the writings on this now famous tree, such as appeared during the comparatively 

 short space of time since it came into notice, were to be collected, we should have material enough 

 to fill a large volume. But as the main object of the present work consists in an endeavour to 

 set clearly forth the systematic characteristics of the various Eucalypts, with a view of facilitating 

 the discrimination of the species, it will not be necessary on the present occasion to excerpt 

 extensively from the writings of other observers ; but it may prove of utility to quote the list of 

 publications on Eucalyptus (and chiefiy on E. globulus) inserted into the " Bulletin mensuel de la 

 Soci^t6 d'Acclimatation de Paris," as far as they appeared in that important periodical, an index 

 of which up to 1877 was given already by Dr. Jules Grisard. {See Bullet, troisifeme serie, tome 

 iii. 59-62.) To this list are here now added notes on some more publications, quoted in Bentley's 

 and Trimen's " Medicinal Plants " (Part 15) and many in addition, to which I had access also ; 

 though this index is far from claiming completeness, the scattered literature even of Eucalypts 

 being only very partially to us accessible here.
