In the above summary it should be noted that the percentage of 
excreta is no indication of what may be considered the percentage 
of infestation, since the excreta become loose and adhere slightly to 
uninfested figs. It will be noted that samples 1 to 10, purchased 
in open market, were free from insect injury except in two cum 1 -. 
In the case of sterilized figs there was. as a rule, a considerable 
difference from the unsterilized figs from the same source. It is 
obvious, as Mr. Smyth informs me, that the heat in many cases was 
not applied sufficiently high, and was not continued long enough to 
entirely penetrate such large masses as 5 or 6 pounds of Layer figs. 
Of the 30 samples examined. Nos. 1 and •>. each containing L0 per 
cent of infestation, Xos. 11. 14, and 25, each containing 2.~> per cent 
of infestation, and Xo. 18, containing 26 per cent, not one could be 
pronounced inedible, and it will be noticed that Xos. 27 to 30, al- 
though containing a considerable percentage of excreta and micro- 
scopic mites, were also considered edible. No. L185 would be pro- 
nounced unfit for human food on casual examination, but in reality.
