At the same time there are, as has been shown earlier in this work, living specimens of Polycystina. 
There is no definite agreement among biologists that all living specimens should be termed 
Radiolaria, and that the name Polycystina should be restricted to the fossil forms of Radiolaria. 
Hence, at the present time, a line of demarcation cannot be drawn between these more than 
interesting forms of micro-marine life.

Tue life-story of a Queen Bee begins really at the moment when the mysterious governing spirit 
within the hive decides that a swarm shall issue—the emigration of a large part of the population 
take place. 
As the old Queen is to be sent away with this swarm, the first and most important preparation 
for the event will be the provision of a successor for her. We now see an extensive work begun in 
the hive. Queen-cells must be built, The building of these queen-cells is undertaken in a very 
different way from the method employed with those destined to contain ordinary workers, or 
ordinary male bees. Instead of being packed together in as little space, and constructed of as 
little material as possible, the queen-cells are made separately, of generous size, and are placed 
usually on the edge of the comb, where abundant space and fresh air are obtainable. 
At first this cell looks very like an inverted acorn-cup, in the centre of which depends a minute 
white speck like a microscopic grain of rice, wherein is enshrined the germ destined, in all likelihood, 
to develop into the future mother of a whole nation. From this egg, after the lapse of three days,

THE BROOD-COMB. 
A very old Brood-comb. The cells, notably those towards the bottom of the comb, have almost lost their hexagonal form 
qwing to the accumulation of pupa-skins within.
