Lindley uses pajjer eighteen and a half inches long by eleven 

 and a half wide, though he remarks that it is rather large and 

 expensive. 



The herbarium of Sir William J. Hooker, at Glasgow, is not on- 

 ly the largest and most valuable collection in the world, in the pos- 

 session of a private individual, but it also comprises the richest col- 

 lection of North American plants in Europe. Here we tind nearly 

 complete sets of the plants collected in the Arctic voyages of dis- 

 covery, the overland journeys of Franklin to the polar sea, the col- 

 lections of Drummond and Douglas in the Rocky Mountains, Ore- 

 gan, and California, as well as those of Prof. Scouler, Mr. Tolmie, 

 Dr. Gairdner, and numerous otticers of the Hudson's Bay Com- 

 pany, from almost every part of the vast territory embraced in their 

 operations, from one side of the continent to the other. By an ac- 

 tive and prolonged correspondence with nearly all the botanists and 

 lovers of plants in the United States and Canada, as well as by the 

 collections of travellers, this herbarium is rendered unusually rich in 

 the botany of this country; while Drummond's Texan collections, 

 and many contributions from Mr. Nuttall and others, very fully 

 represent the flora of our southern and western confines. That 

 these valuable materials have not been buried, nor suffered to ac- 

 cumulate to no purpose or advantage to science, the pages of the 

 Flora Boreali-Americaiia, the Botanical Magazine, the Botanical 

 Miscellany , the Journal of Botany, the Icones Plantarum, and other 

 works of this industrious botanist, abundantly testify; and no single 

 herbarium will alibrd the student of North American botany such 

 extensive aid as that of Sir William Hooker. 



The great botanical collection of the Jardine des Flantes, 

 which is probably the largest in the world, is next mentioned. 

 The herbaria occupy a large room, eighty feet long and thirty 

 wide. 



The other collections are those of De Candolle at Geneva, 

 surpassed by few in size and by none in importance; the Royal 

 Bavarian herbarium at Munich, mostly Brazilian plants; the 

 herbarium of the late Prof. Sprengel, comprising many North 

 American plants; the Royal Prussian herbarium, at Schone- 

 burg; and one or two private ones at Berlin. The whole ar- 

 ticle is highly interesting. 



With the commencement of the present volume of the 

 Journal, of which the number for January is the first, the 

 editors give notice that they will furnish the numbers to all 

 their subscribers, free of postage. This will be quite an item 

 of saving, and will, we hope, be an inducement for individuals 

 to give it their support. From a notice attached to this num- 

 ber, we extract the following, in relation to this subject, and 

 commend it to the attention of all who are desirous of reading 

 a scientific periodical: —
