Mr, W. M. HOLLIs said the lesson Nature would thus teach was 
evidently that ladies should stay at home and gentlemen go out to 
work, 
Mr. WONFOR said he had written a sentence in the paper to that 
effect, but on second thoughts he came to the conclusion that it was 
yather too bad, and left it out. It was as follows :—“ Opponents of 
the Women’s Rights party may argue from this that the duties of the 
females are at home.” 
Some remarks were then made on the Aa/teres of the Diptera. 
Mr. HENNAH said that from their structure and from their position 
on the thorax, he thought they were the remains of wings applied to 
another purpose. 
Dr. HALLIFAX said that the articulation of the a/feres near the 
thorax bore a close rememblance to that of the wing. The position, 
too, corresponded. The four wings of an ordinary insect were, he 
believed, invariably joined to the two last segments of the thorax, and 
in the Diptera the wings were on the second segment, leaving the last 
for the Aa/teres, After experimenting on “ daddy long-legs,” he came 
to the conclusion that the Aalteres were decidedly hollow, and filled 
with fluid. It had been suggested that they might be organs of 
hearing. 
Mr. WONFOR said that fluid circulated in the wings of certain 
insects, and he thought this would make the analogy still closer. It 
had been asserted that the nervures were only stiff and straight and 
solely for the purpose of keeping the wings extended, but anyone 
who had cut the wings of a butterfly must have noticed a fluid oozing 
out, In fact, he believed there was not only a communication in 
butterflies from the nervures internally, but also outwardly to the 
scales. ‘he scales from a live insect were seen under the microscope 
‘to be moist with a greenish fluid, resembling that which oozed from 
the nervures, or, at any rate, from the wings when cut, The existence 
of a fluid would seem to imply a circulation.
