maculatuni, Priraula faiinosa, Cerastiura triviale, var. holosteoides (?), 

 and many other plants. Mr. Davies observed a few ferns, such as 

 Hymenophylhim Wilsoni and Allosorus crispus ; also Lycopodium 

 alpinum, &c. 



Mr. Stark exhibited a new adaptation of the simple microscope, 

 suited for field-examination of the minute parts of plants, especially 

 for Algae and other cryptogams. Besides the lens, supported on a 

 stalk, for holding in the hand, and giving a power of 60 or 70, there 

 is attached a circular glass field for laying the object on, which, if in 

 a moist state, may be covered by another circular disk of thin glass ; 

 by a screw and spring attached the focus can be conveniently regu- 

 lated. The whole is very portable, going into a neat case, about four 

 inches by one in measure. 



Mr. Evans exhibited, from the Experimental Garden, a few inte- 

 resting alpine plants, and a small species of Plantago, raised from 

 Californian seeds. 



Mr. M'Nab exhibited, from the Botanic Garden, two tree-ferns, 

 introduced from the West Indies, by Mr. John Kent. They appear 

 to be undescribed, and are both very prickly. 



Mr. M'Nab also exhibited, fi-om the Botanic Garden, a number of 

 rare and interesting plants, including a complete set of Robertsonian 

 Saxifrages, Marsilea quadrifolia in fructification, Carex Grahami, 

 Hieracium alpinum, with a very woolly capitulum and broadly obo- 

 vate leaves, Aceras anthropophora, &c.
