scribed, all that is required is white paper in half sheets, and tape to 

 meet the increase of bulk. The present plan is, moreover, so com- 

 pact, and the fasciculi are so mathematically uniform in superjficial 

 measurement (that is, if a little dexterity and judgment are used in 

 the mounting, so as to let the thick heads of thistles, for instance, lie 

 in the comers of the papers), that they will lie upon each other like folio 

 volumes. Another advantage over the book system is that a series of 

 genera and species can be taken out and laid side by side for compari- 

 son, and be easily replaced when done with. If I rightly understand 

 Mr. King's method, the latter does not admit of this ; at all events, it 

 cannot be practised with equal facility. Where a cabinet, purposely 

 constructed for holding plants, is possessed, of course tape and paste- 

 boards are not required, the papers lying loose on their respective 

 shelves. In this case I would, nevertheless, still pursue the plan of 

 having genera and species in separate blue and white papers, as above 

 described. — Leo. H. Grindon ; Manchester, May 16, 1843. 



322. Mr. Bahingtoii's ' Manual of British Botany.' We regret 

 that we can do no more in the present number than announce to our 

 readers the appearance of the above work, which we anticipate will 

 ere long become the text-book and travelling companion of every 

 British botanist. The generic and specific characters are of necessi- 

 ty condensed ; but, judging from our hasty glance through the book, 

 they appear to be clear and explicit, and are evidently drawn up with 

 constant reference to the most recent information contained both in 

 continental works of standard authority, and the British scientific 

 journals. We must defer a regular notice until next month. — Ed.

 from the President, from Col. Jackson, Mr. Hogg, and Mr. E. Doubleday. British 

 plants had been received from Mr. Edwin Lees and Miss Twining ; and a collection 

 of specimens from Western Australia, was presented by Mr. John Turner. Mr. Wil- 

 liam Andrews presented specimens of varieties of Saxifraga Geum, collected at the 

 Great Blasquest Island, coast of Kerry, Ireland, one specimen of which had the nec- 

 taries thickly surrounding the ovary. Mr. A. Henfrey exhibited specimens of Leuco-
