Windpipes of Insects: Organs of the Senses in Insects.— 
] have read your article about the windpipes of insects 
(Entom. ix. 62) with much pleasure, and | think you are 
doing good service in thus enlightening our entomological 
friends, so few of them trouble themselves about such matters, 
although they are most interesting subjects for study. Species 
hunting is all very well; but to my mind the wonderful 
variations and adaptations of their organs to their especial 
purposes is by far the more interesting subject of study. 
Who knows anything about their organs of smell? I have 
long had some crude ideas on that subject, and I shall hope 
to discuss that subject with you some of these days.—J. S. 
Bowerbank ; 2, East Ascent, St. Leonard’s-on-Sea. 
[Certainly not sent for publication; but 1 hope Dr. Bower- 
bank will pardon the breach of confidence I commit in 
publishing it. It is lamentable to reflect that we have abso- 
lutely no knowledge of the seat of hearing, taste, or smell, in 
any of the hexapods; indeed, if we have not stood absolutely 
siill since the publication of the ‘ Bybel den Natuura’ in 1783, 
we may be said to have retrograded. I make no apology to 
entomologists for my exultation in having found an approver 
of my views. This exultation is surely allowable, when we 
hear the peans with which the naming of a new beetle is 
hailed.— Edward Newman. | 
Circulation of Blood in Insects.—In the last number of 
the ‘Entomologist’ (Entom. ix. 90) it is stated that Dr. 
Bowerbank discovered circulation in insects. In a magazine, 
named ‘ Ward’s Miscellany,’ of 1838, it says that a German 
naturalist, Behn, discovered it. I should be obliged if you 
will kindly tell me on which side is the error.—Al/red 
Jones; Torquay, March 14, 1876. 
{Il may refer to this subject again hereafter. It will be 
sufficient for the present to state that 1 have ascertained the 
titles and dates of these papers on “ Circulation of Blood in 
Insects.” 1. Dr. Bowerbank’s papers are as under:—“ Ob- 
servations on the Circulation of the Blood in Insects.”— 
‘Entomological Magazine, vol. i. pp. 239—244, April, 1833. 
“ Observations on the Circulation of Blood and the Distribu- 
of the Trachee in the Wings of Chrysops Perla.”—‘ Entomo- 
logical Magazine, vol. iv. pp. 179—185, October, 1836,
