based on morphologic characteristics. Maiden then turns against 
Baker and Smith ^) who differentiate the various species in the first 
place according to the chemical composition of the essential oils pro- 
duced from them. 
In two further publications by the same author 2), Eucalyptus bicolor 
A. Cunn. and E. polyamthemos Schauer are dealt with. 
Finally, the first three parts have been published of a larger work 
on the eucalypts: "A critical revision of the genus Eucalyptus"^). In 
the preface Maiden points out that twenty years have now elapsed 
since the publication of the famous " Eucalyptographia " of M tiller, and 
that in that period much material has been collected by means of a 
large number of observations, which has led to the individual species being 
looked upon from a partly different point of view. The introduction 
consists mainly of the contents of the above-mentioned first paper. The 
first species described is Eucalyptus pilularis Smith, and under this 
designation everything is embraced which up to now has been des- 
cribed under the following names: E. discolor Desf ; E. persicifolia 
Lodd.; E. persicifolia D. C; E. incrassata Sieb.; E. semicorticata F. v. M.; 
E. fibrosa F. v. M.; Var. Muelleriana var. nov.; E. Muelleriana Howitt; 
E. dextropinea R. T. Baker; E. laevopinea R. T. Baker. The second 
part deals with E. obliqua L'Heritier; as synonymous the following are 
mentioned: E. pallens D. C; E, porcera V>€^Vii\.\ E. gigantea Hook, f; 
E. elatus Hook, f ; E. fabrorimi Schlecht; E. fissilis F. v. M.; E.falcifolia 
Miq.; E. nei'vosa F. v. M.; E. heterophylla Miq. The third part describes 
Eucalyptus calycogona Turcz. with two varieties, namely, var. celastroides 
Maiden (syn. E. celastroides F. v. M. and E. friicticetorum F. v. M.), and 
var. gracilis Maiden (syn. E. gracilis F. v. M., E. gracilis F. v. M. var. 
breviflora Benth. and E. yilgarneitsis Diels). As doubtful varieties are 
mentioned: E. gracilis F. v. M. var. Thozetia?ia F. v. M. and E. och'ophloia 
F. V. M. Each part contains a number of beautifully executed plates. 
. R. T. Baker ^) also gives a contribution to the knowledge of the 
Eucalypts, under the title ''On Eucalyptus melanophloia ¥. v. M. and its 
cognate species". 
Fennel Oil. The fennel plants in this neighbourhood have thriven 
well and, in consequence of the great heat, they have also ripened 
well and in good time, so that at this moment new goods are already 
offered for sale. As usual, the large-sized first fruit again fetches this 
year a specially high price, and does not come under consideration 
for manufacturing purposes. As a matter of fact, the Liitzen fruit would
