fa6l that the inse£ts were not simply presented, but were 
collefted by the lady herself who gave them ; and this, 
as measured by the muscular effort required to procure

trouble necessitated in pinning and fixing them in the 
camphor-box, is as commendable in the donor as it is

the personal desire to benefit and help on the colonial 
Museum, even at the expense ot the fatigue and un- 
comfortableness resulting from such an expenditure of 
energy in the tropics ; and as such it called for this 
special reference, both for its own sake, and for the sake 
of creating some beneficial emulation. There does not 
seem to me to be any liberty in, or objection to, my 
mentioning that the lady referred to is Mrs. JENMAN.

and the results published in the Journal of the Linnean 
Society, vol. XXIV.
