number, under which it is described in the “ Sylloge,” in order 
to facilitate reference. This would not have added a page to 
the bulk of the “ Supplement,” and would certainly have saved 
the student a vast amount of time in turning to Indices, 
We have so often referred to this work during its progress, 
that little of commendation is left for us now to say. We are 
glad to welcome the 12th part, and so will all Bryologists who 
are interested in the British Moss-Flora. The only drawback 
is the tardy rate at which the parts make their appearance. 
However, we must be thankful for small mercies. The present 
part concludes the Grimmiaceae, and adds the Schistostegaceae. 
It is, moreover, announced to subscribers that the present com- 
pletes one half of the work. It has occupied nine years to bring 
us up to the middle ; will it take another nine years to bring us 
to the end P Let us hope that better luck is in store for us.
