upright position, and as soon as the contents 

 begin to decompose, many insects will be found. 

 They may be visited erery morning, and the in- 

 sects shook out upon a sheet of brown paper, 

 carried for the purpose. Traps similar in con- 

 struction to those used in houses for catching 

 cock-roaches, fBlatta OrientalisJ and baited as re- 

 commended for the bottles, might also be em- 

 ployed. The aperture should be so small as 

 not to admit mice, which are destructive to in- 

 sects. Old' cellars, subterraneous passages, barns, 

 stables, damp pits, &c. also contain various in- 

 sects, which might be taken by this means. 

 Another method, also very successful during the 

 Spring and Summer, is laying bones (particu- 

 larly marrow bones), with a little meat left on 

 them, horns of sheep, &c. about s:ind and 

 gravel pits, woods and gardens. 



Dung of Horses, &c. An excellent method 

 for those who have the opportunity, for taking 

 beetles from the dung of various animals, is 

 pointed out by Messrs. Kirby and Spence *,
