youngster to collect all the females he could as they emerged from 
the grass. As he caught them he placed them in a paper box 
made out of an envelope, and became somewhat annoyed by 
finding the males not only flying at, but alighting on him in great 
numbers. This was considered another case of ‘‘sembling.” 
Some very extraordinary statements respecting the enormous 
distance to which the males of the Tusseh moth fly in India, 
recorded in Vol. VII. of the Linnean Transactions, were next 
mentioned ; and attention was called to the idea that one of the 
reasons why males were aitracted at times was owing to their 
haying periods of flight. 
A curious confirmation of the idea that the moths had times of 
flight was given on Saturday, May 7th. Mr. Goss had taken a 
female up to Balcombe in the morning, and had not attracted a 
male until between two and three o’clock, between which time and 
a quarter to four o’clock five were attracted. Now, curiously, the 
time agreed exactly with the times at which in every case the males 
Carpini began and ceased coming up, on the 22nd and 26th of 
April. 
May 26th.—‘‘ Microscopical Section.” —On Systematic Recent Examina- 
tion with moderate powers, by Mr. T. H. Henna. 
Whether we regard the extension of our knowledge of Natural 
History, the success of this Section, or our own pleasure in 
microscopic study, Systematic Recent Examination, with 
moderate powers, is alike indispensable. Most of the discoveries 
with the microscope have been made with instruments of moderate 
power and cost, and have resulted from patient, diligent observa- 
tion, and have depended less upon the instrument than upon the 
method and perseverance of the workers. 
Pride in the possession of a fine instrument, and a consequent 
desire to exhibit its powers, often leads to the exclusive study of 
conventional test objects, which, while it gives command of the 
microscope in a special way, and stimulates opticians to improve- 
ments, too frequently arrests original investigation. The ordinary 
work of the Naturalist can, in the first instance, be better pursued
