1879. — Mueller, F. von. " Report on the Forest Resources of Western 

 Australia" (L. Reeve & Co., London, 1879), 4to, pp. 30, with twenty plates. This 

 work, chiefly useful for its plates, figures seventeen Eucalypts, which were precursors 

 of those depicted a little later in the " Eucalyptographia." It contains a chapter on 

 Chemical and Microscopical Examination of Eucalyptus wood. 



1879-1884. — In "Eucalyptographia" Mueller devotes several illustrations to 

 microscopic sections of timber, viz. : — 



1. E. Behriana. A separate plate with sixteen transverse sections of the following 



species : — 



E. amygdalina. E. melliodora. 



E. Behriana. E. obliqua. 



E. botryoides. E. punctata. 



E. globulus. E. polyanthema. 



E. Gunnii. E. rostrata. 



E. goniocalyx. E. Stuartiana. 



E. hemiphloia. E. Sieberiana. 



E. macrorrhyncha. E. viminalis. 



2. E. goniocalyx. On the ordinary plate there are transverse sections of wood, 



magnified 60 and 220 times. 



3. E. leucoxylon. On the ordinary plate there is the following legend : — 



14. Transverse section of wood. 



15. A separate vascular tube, and next to it an isolated woody fibre. 



16. 17. Parenchymatous particles (220 diameters). 



4. E. macrorrhyncha. Three sections on a Supplementary Plate, with the 



following legend, which I quote literally : — 



2. Transverse section of aged wood, the large openings representing the 

 vascular tubes ; the rows of elongated cells constitute the medullary rays ; the scattered 

 cells and those near the vascular tubes are parenchyme (sic) ; the rest show the 

 transverse form of the numerous woody fibres, all closely set and in diameter smaller 

 than the parenchyme-eells. 



3. Tangential section of aged wood; Avide and dotted vascular tubes, rows of 

 cells of the medullary rays cut transversely, sparingly dotted woody fibres, paren- 

 chymatous ampler interstices. 



4. Radial section of aged wood, wide dotted vascular tubes, rows of cells of the 

 medullary rays cut vertically, sparingly dotted woody fibres, parenchymatous ampler 

 interstices. All x 214. 



5. E. rostrata. 



10, 11. Transverse section of wood. 



12, 13. Longitudinal section of wood, (x 200-220.) 



6. E. viminalis. 



12. Transverse section of wood, (x 220.)
