14^ LETTERS TO MR. GIBB [CHAP. xv. 



and Mr. Moens were good enough to take in supplying me 

 with fresh specimens) as to the species of these bloodsucking 

 pests which you have in the Forest. Would you tell Mr. 

 Moens about this when you see him, with my compliments 

 and thanks ? I think you meet sometimes. I am longing 

 to hear something of the military experiences. 



OcioberZ, 1895. 



I am very much obliged to you for your letter received 

 this morning, and (as you kindly allow me) I will just say 

 what I should particularly like, but please believe me I 

 should be very sorry to be really troublesome. First, about

 which would be difficult to get, and I think plenty of the 

 beetle (or at hand), but, for the mangold, if I could get 

 them, I should very much like some of the Spotted or Black 

 millepedes w r hich were such pests earlier in the year. I 

 am afraid though it is too late now. The only other thing 

 which I am very much wishing for is a good specimen of
