the quotation of the titles of works of reference and the names of

The Completion of Saccardo's Sylloge Fungorum.—Eight 
yearsago the first volume of this great work appeared, and this has 
been followed by others in rapid succession until now we have the 
eighth and final volume of the series. In these thick volumes, which 
aggregate more than eight thousand pages, nearly thirty-two thousand 
species have been described (exactly, 31,927). The completion of so 
great a labor in so brief aspace of time must excite at once our wonder 
and admiration. We have herea work of vast extent, whose first and 
last volumes are near enough together in time, so that they are not ap- 
preciably separated by any change in plan, due to a change of view on 
the part of the authors. Whatever we may say of the plan of the 
work, and however much we may wish that a different one had been. 
adopted, it is comfortable to know that here at least is a book comple- 
ted upon the lines laid down by its author less than a decade ago. It 
is cheerful, also, to think that a generation has not died during the 
publication of the work, but that nearly all who saw its beginning have 
seen its completion. Thus the depressing influence of De Candolle's 
** Prodromus,” dragging its way through fifty years to incompletion, is 
counteracted, and we may again hope to see great undertakings inau- 
gurated. 
If we take the great masses of families as worked in this book, and 
make a distribution in an approximately natural system, we get a better 
idea of the numbers and extent of thefungi. For convenience of ref- 
erence the number of species in each family is given, and the total 
number in each order or class.
