a darker and lighter colour. Next the cornea is a broad band 
of dark pigment called the outer dark zone; this is followed 
by a pale band called the outer white zone, eiichks is followed 
by another dark band called the middle dark zone, followed in 
turn by a white line called the inner white zone, after which 
comes the bulb of the optic nerve heavily charged with a dark 
‘pigment, and which is called the inner dark zone. The differ- 
ence in colour in these various zones arises from the greater 
or less amount of dark pigment contained in them. How 
these different zones act in the transmission of the luminous 
ether is not known. If a crayfish is examined with a light in 
a darkened room, the cornez are seen to glow like two small 
points of fire. 
This brings us to the end of our task, which is not a treatise 
on the crayfish, but a report of the work accomplished during 
‘the Session by the Microscopical Section. 
HONEY-BEES IN WARM CLIMATES. 
At the evening meeting of December 27, 1899, the following 
query was submitted to the members: “It is said that bees 
—say British bees—when taken to a genial sub-tropical 
climate, where there are flowers all the year, cease to store 
honey as they do in the old country. Is this true?” In 
the course of the discussion which ensued, the following im- 
portant communication from Mr Robert Grieve, of Brisbane, 
was read by the President :— 
“As to the question whether bees do not store honey in 
warm climates, I make answer that there is not a particle of 
truth in it—as to Australia, at least. Bees store honey in 
“much greater quantity and much quicker near Brisbane (i.e., 
in South Queensland) than in England—wax also. These 
and constant. ucalypts are their chief food-supply. Tons 
of t honey can be bought here at any time at a price something 
under 2d. per lb.
