* The Droseras are real catch-flies. If examiaed, especially in the morning, a number of the 

 leaves will be found to be folded or rolled inward. These closed leaves, when opened, will be seen 

 to contain, usually, from one to thi-ee or four minute winged insects, which the leaves have caught 

 and will hold tightly clasped until their substance has been absorbed by the plant. In one instance 

 the commencement of this operation was observed when a fly larger than an ordinary house fly was 

 the prey. In this case, while the fly was resting upon the surface of the leaf, sipping the glittering 

 drops of nectar, a single glandular bristle on each side of the leaf was gently bent over on to the back 

 of the fl\' and held it down, which operation was followed, no doubt, by the pinning down with more 

 bristles and the closing of the leaf, when the capture would be complete; but unfortunately the ob - 

 server could not wait for the flual result.
