rich forests of the beech, Fagus Cunninghamii, and of the various species of 

 Eucalyptus. 



With the above it is interesting to compare the impressions of a visitor, 

 as given by Saunders* reporting the tour of the British Association in Aus- 

 tralia. More detailed studies of limited areas are those of Osborn and Hardy, 10 

 the latter giving an interesting account of a scrub vegetation termed "mallee," 

 as it occurs in a portion of Victoria with 12-20 in. annual precipitation. This 

 seems to be a semi-desert association of woody plants growing 6-10 ft. high, 

 at times forming a rather open stand, but often almost impenetrable thickets. 

 Shrubby species of Eucalyptus with vegetative habits of reproduction pre- 

 dominate with the almost leafless "broom mallee," Exocarpus spartium, upon 

 sandy ridges. 



Osborn" describes the climatic conditions of the region about Adelaide 

 which possesses a winter rainfall, 70 per cent of the total annual precipitation 

 being between the months of May and October. Evidences remain that the 

 plains upon which the city of Adelaide now stands were originally well wooded 

 with various species of Eucalyptus, while the low sandy flats separating the 

 plains from the sea show associations of the mangrove. Avicamia officinalis. 

 and of shrubby species of Salicornia. Portions of the coast have in addition 

 low sand dunes with grasses and shrubs. Notes upon other associations of the 

 plains and mountains are also given, while not the least interesting is the brief 

 study of the remarkable similarity of leaf forms existing in widely separated 

 families, notably the sickle-shaped leaves of certain species of Eucalyptus 

 and cicada —Geo. D. Fuller. 



Meiotic divisions— Owing to views put forward by Lawson 12 as the result 



stages in a species of the same genus, and her conclusions do not agree in the 

 main with those of Lawson. 



In the resting nucleus, the chromatin granules are found to be held in the 

 meshes of a so-called fine linin network. This network, though perhaps not 

 so extensive as it appears, is not altogether a fanciful structure. At no time 

 in the early prophases was the individuality of the chromosomes apparent,
