ANTS. We 
with the care of their younger sisters, and then going on 
to the adaptation of the formicary to its growing requirements, 
in the course of which much labour is expended. The 
next stage seems to be that of catering for the household, 
about which more will be said presently. Probably the 
final stage of instruction is that connected with their duties 
in connection with police or military work, defensive first 
and offensive afterwards. That they do learn to do all 
these things systematically no one can doubt, though we 
do not know anything about the methods of instruction 
followed; nor do we yet know whether the whole of the 
education of the family is left to the queen, or is wholly or 
in part delegated to some of the older workers as they acquire 
the experience required and the number of workers increases. 
Much—very much—yet remains for us to learn about the 
habits of these little folk; and although we may be wiser 
for considering their ways than we were, yet we are only, 
so to speak, beginning to begin to learn the whole of the 
truth. 
I do not propose here to repeat the many interesting 
stories that have been told about ants—many of which are, 
doubtless, fully entitled to credence; but I shall, instead, 
devote this Address to a broader review of the main facts. 
It may, however, be remarked here that, in most respects, 
but not in all, ants do undoubtedly show a much higher 
grade of intelligence than any other invertebrate, or, for 
that matter, than a great many vertebrate animals do. With 
this power of adapting themselves to unfamiliar conditions, 
which may fairly take rank as reason, there is a very wonderful 
development of that lower grade of intelligence transmitted 
to the generations of to-day from their ancestors for count- 
less centuries past, which we speak of under the general 
name of instinct. Which act out of many shall be referred 
to the one category, and which to the other, it is often hard 
to say. Sir John Lubbock gives many interesting illustra- 
tions upon these points, which there is not time to quote 
in this Address now, nor room in the Zransactions to print 
afterwards. I may, however, in concluding this section of 
my Address, express the admiration which we must all 
feel for the wonderful altruism displayed by the queen
