however, the similarity of physiological structure may be only 

 apparent; in the mean time, this list may afford data for 

 future reference to the physiological enquirer. One useful 

 fact the gardener may be reminded of by this communication, 

 viz. that " all trees upon walls which had copings were per- 

 fectly protected, excepting those whose shoots projected be- 

 yond the perpendicular influence of the coping; under such 

 circumstances the shoots of vines were quite cut off." 



It is also worthy of notice, that the variegated varieties of 

 ^'cer campestre and Aristoteh'a Macqui were the only in- 

 stances in which a variegated plant appeared to be more 

 tender than its parent. It appears also, that the ovaria of the 

 blossoms of fruit-trees may be destroyed, and at the same 

 time no apparent injury be sustained by the petals and 

 stamens, through which the cold must have penetrated. " It 

 also appeared, especially with the pears, that the fecundated 

 ovarium was more susceptible of cold than that which was 

 unimpregnated." The reader will learn from this last fact, 

 with what curious accuracy the observations were made. 



56. On the Propagation of Zamias. By Mr. Francis Faldermann, 

 C.M.H.S., Chief Gardener in the Imperial Botanic Garden at 

 St. Petersburgh. 



The Zamia is a palm with a large scaly protuberance above 

 the surface, from the centre of which the leaves spring. De- 

 stroy the centre, and buds and leaves will issue from the 

 scales, which may thus be separated, and form so many dis- 

 tinct plants. The same thing has been done in this country 

 with Zamia, Cycas, and some bulbous genera, and is probably 

 applicable to other palms, to many bulbs, and to fleshy-rooted 

 plants as Tamus, &c. 



When the heart is destroyed, it is advisable to fill it with 

 dry sand, to absorb moisture, stimulate the healing process, 

 and prevent decay.
