BOOK NOTICE. 



The School Fern-Flora of Canada ; by Prof. George Lawson, 

 Ph.D. LL.D., F.R.S.C, pp. 221-251, 1889. We have to thank our 

 esteemed member Dr. Lawson for a eopy of his School Fern- Flora of 

 Canada, which has been published as an appendix to a reprint of Dr. 

 Asa Gray's " How Plants Grow," lately issued by Messrs. A. &, W. 

 Mackinlay, of Halifax, N.S. The whole volume containing both works 

 will be supplied by the publishers for 75c, but a discount of 20% will 

 be allowed if ten or more copies are taken. As is well known, Dr. 

 Lawson has made a special study of our Canadian ferns, and there is no 

 doubt that the publication of this paper will be welcomed by many of 

 our members who are frequently enquiring for a small and intelligible 

 work upon this favourite branch of our native flora. There are no 

 plants which are so universally admired as urns, and none of greater 

 interest than those which grow wild in our northern woods and rocky 

 ravines. Botanists and lovei's of nature are now provided with a means 

 of identifying any fern they may find growing wild, for this little work; 

 which is illustrated by one plate upon which 17 genera are figured, 

 11 comprises descriptions of all ferns known to inhabit the Dominion
