F.R.S., F.L.S., on ‘ The Perception of Light by Plants.’ The 
main factors of his address were well emphasised and illus- 
trated by numerous lantern slides showing his experiments 
with the epidermal cells of the leaf of the Spiderwort (commonly 
known as the ‘ Mother of Thousands’). Mr. C. A. Cheetham 
also showed a large number of his charming coloured lantern

Heron Killing a Kestrel.—My friend, Mr. Bryan Lang- 
mead, writes to tell me of an encounter of which he was an 
eye-witness, in the following words :—‘I saw a Kestrel in the 
airand a Heron by a stream, when suddenly the Kestrel gavea 
a swoop upon the Heron which curled up its neck, and ran its 
beak right through the Kestrel, killing it instantly. I had 
a look at the Hawk afterwards, and all its ribs were broken 
by the bill of the Heron.’—-W. W. Mason.
