even fatally, both the plants and the operator. With regard to its 
injury to the plants, I believe it can always be sufficiently obvia¬ 
ted by largely diluting the poison with flour or ashes. The former 
is preferred, because if applied when tlie plants are wet with rain 
or dew, it makes a paste which prevents the poison from being 
blown from the vines. Experiments would seem to show that the 
poison is about equally effective upon the insects, whether diluted 
with five, ten, fifteen, or even twenty times its bulk of flour. And 
the more it can be diluted without destroying its efficacy, the lees 
injurious, of course, it will be to the vines, and the more widely 
it can be diffused at the same expense. 
Considering the extremely poisonous nature of this substance 
and the very considerable extent to which it has been used, it is 
remarkable that, so far as I am aware at least, no case of death 
from its use as an insect-destroyer is on record. The onlv proba¬ 
ble exception to this statement that has come to my knowledge 
was in the case ofa child four years old, in my own neighborhood, 
■wio, together with a still younger brother, was taken suddenly 
sick with very suspicious symptoms, after playing amongst some 
potato vines near the house, to which Paris-green had been applied. 
T ese children were taken with griping, and vomiting, and purg- 
liig o green colored matter, and in a week from the time of the 
attack, the older one died. This case was, to say the least, of so 
very suspicious a character, that it made me much more careful 
m usmg and recommending this poison, and I immediately pub- 
ished a caution in some of the papers against the use of it in any 
place to which children would be likely to resort. 
With regard to to the method of applying this substance, there is 
no simpler and more effectual way than to shake it from a o-auze 
ag tied to the end of a stick, the operator always takino- the pre 
caution to stand so that the wind shall not blow the powder to-

Tlie remarkable success which has attended the use of the Paris 
green for the destruction of the Potato-bug, has- very natural! 
raised the query whether this poison would not be an equally ei 
ective remedy against other noxious insects, and a good man’ 
m eres ing experiments have been performed to test this question 
? xpe ™“ c e shows, what we indeed should suspect, that this poisoi 
is speedily fatal to all foliage-eating insects, but not to those whici
