and it is also very probable that the connective threads, in many

and that the middle-lamellary protoplasm is the remainder of the

wall much compressed together, and therefore only visible, or dis- 
tinctly visible by the swelling of the cell-wall.

WILLKOMM’S ARRANGEMENT OF THE VEGETABLE KINGDOM.— 
In a review of a recently published “ Bilder Atlas, ” by M. Will- 
komm, in the Botanisches Centralblatt, the following i is given as 
his proposed arrangement of the vegetable kingdom: 
FIRST KINGDOM, SPOROPHYTA. 
Division I. Thallophyta. 
oma I, Mycetoideæ, containing the orders 1. Myxomycetes and 2. Fully 6 
1. Phycoideæ, containing the orders 3. Lichenes, and 4. Alge. 
Division TI. Cormophyta. 
oe 11. Protonemacez, orders 5. Hepatice and 6. Musci 
Class 1v. Prothallionate, orders 7. Eguisetine; 8. PEENE and 9. Filicine. 
SECOND KINGDOM. SPERMATOPHYTA. 
Division III. Gymnosperme. 
Class v. Pseudocarpe, orders 10, Cycadee ; 11. Taxinee ; 12. Conifere; and 13. 
Ambigue.
