gardens, with a view to ascertain if the Hies were in reality 

 Attracted by the kerosene oil, or if their getting into it was purely 

 accidental. Our experiment showed that there is nothing acci- 

 dental in connection with their getting into the oil, but showed 

 most clearly that the kerosene really attracted the flies. A vessel 

 containing some kerosene was placed in the forks of a tree about 

 18 inches above the ground, and at a point where ordinary 

 specimens of the flies are never noticed. Within 15 minutes after 

 having placed the vessel in the position above mentioned dozens 

 of Hies could be noticed moving about the trunk of the tree 

 making their way to the oil ; and 18 hours later Mr. Newman 

 removed and counted V24 fruit flies from the one vessel. Female

I n the article from whiqh the above quotation is made, a figure 

 is given of a self -feeding tin for the capture of the fly. It should 

 be noted that the tins must be shallow, such as lids of cocoa tins, 

 &c and it is found in practice that they are most effective when 

 half fu 1, and inclined at a slight angle. It is reported in the
