siderable experience of cardiac disease. We cannot discover from what it is 
reprinted. Mayhap it is an original essay. 
The Triumph of Evolution, and other Poems, by Joseph Merrin. London : 
Longmans, 1871. The title sufficiently conveys what this work is about. 
We pass no opinion upon it. 
A complete Course of Problems in Practical Plane Geometry , by J. W. 
Palliser. London: Simpkin & Marshall, 1871. The lecturer on geo- 
metrical drawing at the Leeds School of Art and Science has here given 
what appears to be a useful work. It is accompanied by no less than 260 
diagrams j and so far as we have seen, it is simple enough, provided the 
student goes on step by step through its pages. We think Mr. Palliser has 
done well to produce it. We fancy he has supplied a want much felt.
