For an account of this resin see Maiden (53). Lauterer (33) 

 Ihas also given an account of this resin. 



The following unpublished note is by the late K. H. Bennett 

 •of "Ivanhoe," via Hay: — "Another substance called by the natives 

 "Tecabalah," and resembling pitch or wax exudes from this tree 

 at certain times of the year. When it first exudes it is soft and 

 very tenacious and exactly like wax, and assumes the form of 

 ■drops, varying in size from that of a pea to that of a nut, these 

 gradually harden by exposure to the air and eventually are found 

 lying around the foot of the tree. This substance is used by the 

 blacks for the same purposes as we use wax, and answers just as 

 -well, it merely requires heating." 



Yerbenace^. 

 Avicennia officinalis, Linn., "Mangrove." 



Forster erroneously supposed this species to produce a resin, 

 which led him to describe it as A. resinifera, (Kirk). See Agathis 

 ■australis, infra.

E. Schauer has described a new kino from Myristica. Pharm. 

 Journ. [iv.] 3, 117. Joum. Ghem. Soc. Abstr , lxxii., 278. It 

 should be looked for in our M. insipida of the Northern Territory. 



MONIMIACE.E. 



Atherosperma moschata, Labill., "Sassafras." 



The resin contained in the bark of this tree has been examined 

 % Zeyer (Pharm. Viertelj., x., 517), an abstract of whose paper 

 appears in Gmelin's Handbook. The following is his account of 

 it. The bark previously exhausted in water, is exhausted with 

 very weak caustic potash ; the solution is allowed to stand till 

 <3lear, and the resin is precipitated by hydrochloric acid. The 

 precipitate is indigested with alcohol, the extract evaporated, and 

 the residue boiled with water, and dried. Brown-red, melts at 

 104° 0. Dissolves easily in caustic alkalies and their carbonates,
