be a double sting. On examining its antennoe, I found 

 them hooked; this is a characteristic of the male. I at 

 once saw that S. S. had been describing the male organ of 

 Odynerus ; but still I do not understand his article, for he describes 

 and figures the poison bag ; and of course no such organ exists, so 

 far as I know, in the male Odynerus any more than it does in the 

 drone, or male hornet, or other wasps. I was preparing this double 

 sting for the microscope, when, in removing it from a piece of glass 

 (on which it had dried), I lost it, much to my chagrin, for the 

 males of Odynerus are not very common — at least, I have not been 

 fortunate enough to fall in with them frequently ; however, one day 

 I found a male Odynerus dead on the window, and therefore at 

 once tried to mount this portion of the creature. I have not 

 seen any notice of this peculiar formation anywhere but in Science 

 Gossip; will our readers tell us all they know on the subject ? I 

 may just say that the two Odyneri I have mentioned were different 

 varieties.

We have copied the drawing of this remarkable organ, which 

 Dr. George proves to belong to the male, Odynerus, from the 

 Vol. of Science Gossip, above referred to; it will be found on 

 Plate 31, Fig. 3.

Ciliary Processes in the Eye of an Ox.— A thin vascular 

 membrane called the Choroid lies between the Sclerotic coat of the 

 eye and the Reti?ia (or expansion of the nerve of sight). At one 

 part of the choroid is a series of folds separated from one ano- 

 ther by deep furrows ; these folds are the Ciliary Processes. In 

 the human eye they number 70 to 80 ; they have the appearance 

 of a regularly plaited frill, and are very richly supplied with blood- 

 vessels.
