referred to, under this point of view, I think I am fairly entitled to 

 repeat from INSECT TRANSFORMATIONS, p. 403, that it " does not 

 advance a step in demonstrating a circulation in insects similar to that 

 of other classes of animals." 



I have given details at length from M. Straus-Diirckheim, in the 

 ALPHABKT OP INSECTS, with a figure of the heart of a cockchafer, 

 together with the opinions of two of the most distinguished German 

 physiologists, Meckel and Herold, showing that they were all well 

 acquainted what is now claimed as a discovery.

HERMAPHRODITE BUTTERFLY. In the autumn of last year, I had 

 a butterfly sent me to make a drawing of it, being what is commonly 

 termed a malformation or lusus natura. I herewith send you a du- 

 plicate (pardon the rudeness of finish ; self-taught labourers, with 

 nothing but nature to follow, often work to a disadvantage). Should 

 you be able to give any rational account of this, of the cause why it is 

 thus bisexual, I shall, with others of your readers, feel much obliged. 

 The insect was caught near Coventry in June. Similar specimens have 

 been in the possession of the curious, and Captain Brown, in the book 

 of butterflies, records five or six of them. We see the effect ; but as 

 all effects have a primitive cause, what, I may inquire, is that cause 

 in the present instance ? L. W. CLARKE, Sec. Birmingham Entomo-

 nearly fledged, and placed them in a cage on a wall some distance off.
