2. Messrs. Baker and Smith of the Technological 

 Museum exhibited a section of the timber of Callitris 

 intratropica, recently received from Northern Australia, 

 upon which had crystallised out a quantity of guaiol, the 

 sesquiterpene alcohol which occurs in the timber of all 

 species of Callitris. Guaiol has been obtained in quantity 

 from the timber of the " White Cypress Pine," Callitris 

 glauca, and its occurrence in this genus was notified to this 

 Society at the August meeting of last year, and is recorded 

 in the Society's Journal, p. 170.

 genus known to occur in our State being T. trichiurus (T. 

 dispar) from human beings, T. crenatus from the pig, and 

 T. nodosus from the mouse, all three however being uncom-
