MYCOLOGIA SCOTICA.* 
Unfortunately pressure of matter in our last issue prevented the 
insertion of a notice of this volume. It is with unfeigned pleasure 
that we now direct the attention of our readers to the fact that 
the long promised Mycologia Scotica has appeared, that it makes 
a good substantial volume, is clearly and neatly printed, and is, in 
fact, all that such a work should be. 
No one was more fitted than the author to have undertaken it. 
He has made himself so practically acquainted with the higher 
fungi, as they are usually termed, of Scotland, and worked for 
some years so indefatigably in hunting them out, that his ex- 
perience rendered him the right man for the work. Add to this 
his active participation in the work of the Cryptogamic Society 
of Scotland, and his zealous co-operation with all the Mycologists 
north of the Tweed, and his fitness is fully assured. 
* Mycologia Scotica. The Fungi of Scotland and their Geographical 
Distribution by Rev. John Stevenson. Edinburgh, 1879.
