22 HISTORY OF BRITISH MOSSES. 



Miiller, in the 'Botanical Gazette/ has suggested a very 

 simple plan of preserving the leaves of Mosses and similar 

 plants, especially such as are adapted for microscopic obser- 

 vation, — between thin plates of talc, which may be immersed 

 in water without injury. A short description of this mode 

 of preservation will be found in the Appendix.
