500 Effect produced on certain Plants by Frost, fyc. 



in the blossoms of the Strawberry, it was the ovaria which 

 were destroyed, and that the stamens were but little injured. 

 This therefore shews that the ovarium of fruit is so delicate 

 in its organization, that a degree of frost which is incapable 

 of affecting the fleshy calyx, the petals, or the stamina imme- 

 diately enclosing it, will entirely destroy the ovarium through 

 all those envelopes ; and that the ovarium once affected, no 

 power is left in the uninjured calyx, even of the Apple or 

 the Pear, whose fruit is the consequence of the enlargement 

 of that organ, to proceed further in its growth. It also 

 appeared, especially with the Pears, that the fecundated 

 ovarium was more susceptible of cold than that which was 

 unimpregnated.
