‘took two more insects, a mature male and female, separ- 
“ately. Although the cage was quite large, there was a good 
‘deal of scrambling and fighting among the males when the 
‘‘newcomers were introduced. The new male, with five 
‘females to choose from, all already fertilised, settled upon 
‘‘the maimed female. A few days later, I found two insects 
‘‘in connection. They were placed in the cage with the rest 
‘‘in this condition. Next morning I saw that the fresh male 
‘had left its female, and was in connection with the maimed 
‘fone. 
‘* Four males in succession, therefore, had ‘ preferred ’ this 
‘mate, out of a possible four, five, or six. Moreover, she 
‘‘was constantly in connection with one of them, while the 
‘“‘rest were often left unsought for some days together. I 
‘thought at one time that the reason of these phenomena 
“‘might lie in a purely mechanical fact: the female in 
‘‘ question, being maimed, could not move so quickly as the 
‘rest, and so could not escape the advances of the male. 
“But I only once saw a male shaken off by a female—the 
‘‘first male mentioned above: and that female was a virgin. 
‘* When once fertilisation by one male had taken place, the 
‘‘ female remained passive at the approach of others. When 
‘‘the third and fourth males were introduced, all the avail- 
‘able females had had connection. The experiment is not, 
“of course, ‘pure;’ no experiment made in captivity is. 
‘« Still, the insects took to their confinement very well; feeding 
‘‘heartily and breeding readily. I record the facts for what 
‘they were worth, and shall be glad to answer any question 
‘“as to possible sources of error that may occur to the readers 
‘‘of them. Another watcher beside myself has had the 
‘‘insects under pretty constant observation, and can confirm 
‘the above account.”’ 
The President and Prof. Poulton made some remarks on 
the observations recorded in Prof. Titchener’s paper.
