Vol. ii., p. 327). I have mentioned tliese statements to 

 indicate how easily a whole group of substances may be 

 condemned on the unsatisfactory behaviour of perhaps but 

 one member. What the species of Eucalyptus was from 

 which that kino was obtained it is not now possible to 

 say. The present day E. reslnlfera only exudes kino in 

 very small amount, so that it could not be collected in 

 su indent quantity to be of any use commercially, even if the 

 kino was of use for tincture, which it is not. It is probable 

 that the " Botany Bay kino " above referred to was the 

 product of several species of Eucalyptus collected indis- 

 criminately, and owing to the facility with which it gela- 

 tinized in tinctures, it probably contained a predominance 

 of kinos obtained from such species as E. pilularis, E. 

 pipi'iitu, E. hcemastoma, etc., trees which were at that 

 time plentifully distributed throughout the vicinity of 

 Botany Bay. That this is so, is shown from the description 

 given by Dr. Pereira 1 of the kino from Botany Bay that 

 he had met with, which was in irregular odourless masses, 

 many of which were in the form of tears. Some were 

 almost black, and when digested in water, swelled and 

 became soft and gelatinous, like red currant jelly. The 

 kino also acted similarly when digested in rectified spirit. 

 There seems little doubt from the above that that particular 

 sample of kino was of considerable age, and that it was 

 obtained from species allied to the " Stringybarks," or the 

 " Peppermints," because with age all this class of kinos 

 become almost black, and are then but little soluble in either 

 water or alcohol, but swell up like a jelly. The sample 

 could not have been obtained from E. siderophloia, which 

 species has been thought to have been the original E. 

 resinifera, because the solubility of the "Ironbark" kinos 

 in water is but little impaired by age.
