I should perhaps add before concluding^ that my pretensions to 

 attempt a work in this difficult department of Botany rest, amono- 

 other grounds, on my possessing an extensive collection of Grasses 

 made by myself, not only throughout this island, but also in the 

 West Indies and the southern parts of North America, as well as, on 

 an unlimited freedom of access to the Herbarium of the Royal Bo- 

 tanical Society of Edmburgh, and to the rich collections of Professor 

 Graham and of Dr Grenlle of Edinburgh, and of Professor Balfour 

 of Glasgow.
