17. Mr. R. H. Cambage, in a presidential address delivered before the 
Institution of Surveyors, N.S.W. (“ The Surveyor,” 81st January, 190S), took for 
bis subject “ Botany as an accessory to Surveying,” and (particularly pp. 14, 15) 
gave a number of instances of the relation of plants to geological formations. 
18. The same author in Proc. Linn. Soc. N.S.W., xxxiii, 55 (1908) has a 
note on Eiicalyptus Bancrofti on granite. 
19. Mr. J. F. Campbell, L.S., read a paper on “ Soil Physics ” before tbe 
Institution of Surveyors, N.S W. (“The Surveyor,” 31st May, 1909), which contains 
specific instances of the partiality of species for certain geological formations. It 
is a valuable paper from a competent observer, who has given attention to the 
subject for many years. 
20. In Proc. Linn. Soc. E.S.lf’., xxxiv, 313 (1909), R. H. Cambage has a 
valuable paper on “ Acid and basic rocks on Monaro, and tbe vegetation they 
support.” 
Mr. T. Stephens, M.A., told me many years ago that, as regards the following 
Tasmanian species, he has never seen Eucalyptus Bisdoni, Hook, f., grow on any¬ 
thing but mudstone, while E. cordata, Labill., grows in decomposed volcanic rock 
(greenstone, diabase), not in recent volcanic rock (basalt).
