The Mixture (No. 5) might be used in the

tion, but on account of there always being egg's, 
the ojieration would not be effectual, and as the 
former directions completely answer the end re- 
quired, they will be found far more proper to be 
attended to. 
As this tribe of insects, especially the latter 
described, have caused much injury, and interest 
for its eradication, and much doubt whether or no 
it ever will be destroyed, with advantage to the 
plant it infects, I may be allowed to request my 
friends to let due attention be paid to the above 
operations, and I trust it will be found advan- 
tageous, and prove its destroying ju'operties. 
Immerse a few leaves much infested with the Spider 
all over with the above Mixture, and examine 
the leaves a day or two after with the mici'oscope, 
this will suffice to prove the effect. It must be 
observed, that the eggs that may be on the leaves 
will not be desti'oyed by it, and therefore may, in a
