of the specimens selected. This first issue includes forty specimens of 

 these minute plants, which have been obtained chiefly from the three 

 northernmost counties of Britain, Northumberland, Cumberland, and 

 Durham. Of the Lecanora no less than ten specimens find a place 

 in this fasciculus, these are followed by the Cladonia with six, while 

 the Peltigera and Callema are represented by three specimens each, and 

 the Ramalina by four. 



The arrangement reflects great credit on the compiler, and the student 

 will find this work brings valuable assistance to the investigation of 

 these lowly yet interesting organisms of the vegetable world which 

 engage his attention.
