emphatically that such a condition of things should not be tolerated.

CCOCXCV.—GREAT FROST OF 1895. 
The effects of a severe frost on a garden ot be estimated im 
mediately. Species which at first sight seem ferentis sped: recover

plants have experienced in the p ing summer e wood 
has been well ripened they will stand an amount of cold which under 
other circumstances would be fatal. 
At the end of the summer succeeding a severe winter it is possible to

Kew, and the following notes give the results. The labour of compiling 
a list showing the effects of the frost on individual species would have 
been greater than any useful result which could have been derived from 
it. A brief review has only therefore been attempted in general terms,
