as far as bodily structure is concerned—namely, males and females. 
The wonderful part in the history of the Termites is, that not only is 
there a rigid division of labour, but nature has given to each class a 
structure of body adapting it to the kind of labour it has to perform. 
The males and females form a class apart; they do no kind of work, 
but in the course of growth acquire wings to enable them to issue forth” 
and disseminate their kind. The workers and soldiers are wingless, ' 
and differ solely in the shape and armature of the head. ‘This member 
in the labourers is smooth and rounded, the mouth being adapted for 
the working of the materials in building the hive ; in the soldiers the 
head is of very large size, and is provided in almost every kind with 
special organs of offence or defence in the form of horny processes

resembling pikes, tridents, and so forth. Some species do not possess 
these extraordinary projections, but have, in compensation, greatly 
lengthened jaws, which are shaped in some kinds as sickles, in others 
as sabres and saws. 
The course of human events in our day seems, unhappily, to make 
it more than ever necessary for the citizens of civilised and industrious 
communities to set apart a numerous armed class for the protection of 
the rest; in this nations only do what nature has of old done for the 
Termites. The soldier Termes, however, has not only the fighting 
instinct and function: he is constructed as a soldier, and carries his 
weapons not in his hand, but growing out of his body. 
Whenever a colony of Termites is disturbed, the workers are at first 
the only members of the community seen; these quickly disappear 
through the endless ramified galleries of which a Termitarium is
