advantage of having been made on young Droseras grown 
from seed. ‘The unfed plants are thus much more effectually 
starved than in experiments on full-grown plants possessing 
already a store of reserve matter. It is therefore not to be 
wondered at that Biisgen’s results are more striking than 
Kellermann’s and Von Raumer’s or my own—thus, for 
instance, he found that the “fed” plants, as compared with 
the starved ones, produced more than five times as many 
capsules, while my figures are 100: 194, Bisgen gives a 
good résumé of the whole subject, and sums up by saying 
that the demonstrable superiority of fed over unfed plants is 
great enough to render comprehensible the organisation of 
the plants with reference to the capture of insects.—F. D.]
