HERE is no doubt shit a see impetus has been given to the 
at dy of Rusts by Klebahn’s notable book on the heterccious 
‘teceee @, It has enabled students to see what had already been 
d 'y the various Piviales ers on this important group, and has pro- 
vided a good starting-point for further observation and research. 
Mr. McAlpine’s book on Australian rusts takes up the subject for 
that far-away land, and it is remarkably interesting to read the 
records of the rusts for a country where the plants that Ky the 
part of hosts vary so much from those in Europe. One striking 
hetercecious, only four species, so far, have been proved to change 
their host during their life-cycle ; three of these a w on Graminea, 
with their ecidial stage on various chaperone, the fourth, Pue- 
cinia earicis, produces its ecidium on Urticac "All the others are 
autcecious, and complete their life-history on ne host-plant. An 
other remark of fh is that, on some of the most predominant 
yrtacee and Proteacee, rusts are practically 
absent; in the latter order only one uredo is recorded. There is 
no authenticated rust on any Eucal ptus. A number of species 
have been introduced into the country with their special hosts, and 
a separate list m4 these is given 
In first part of the book the whole history and theory of 
rusts is dealt with. The fungus is described and explained in 
its stages, in such a way as to make the subject intelligible and in- 
teresting to » non-scientific reader. we second part gives dia-
