ONE-SIDEDNESS. 85 



The seeds I principally noticed were those of Odontites 

 lutea, Fumaria capreolata, Amaranthus blitiim^ and 

 Veronica, and I can quite confirm Mr. Moggridge's remark 

 that, by the instrumentality of the ants, the weeds from 

 the cultivated ground got planted on the wild ground, 

 where, otherwise, they would hardly have gained a footing. 

 ]Mr. Moggridge has wisely abstained from saying that all 

 ants in the south of Europe store seeds, but he has men- 

 tioned the species which he has observed to do so, and, as 

 probably few of our readers will fail to read his book, we 

 need not continue this portion of the subject further. 



How frequently have we noticed that Entomologists, who 

 have collected diligently for years^ in one locality, seem im- 

 pressed with the notion that the experience they have 

 obtained ought to be identical with the experience of others 

 in distant localities, which are exposed to different atmo- 

 spheric influences of wind, rain, and sun. And if we extend 

 our comparison beyond our own island, still we find the 

 same unwillingness to conceive the possibility of a state of 

 things different from one's own actual experience. 



Whether it will ever be possible to contrive some plan by 

 which Entomologists of dilferent countries shall be conveyed 

 from one country to another, with the view of enlarging 

 their own ideas, and those of the sedentary Entomologists 

 with whom they are brought in contact, is a point which 

 will, ere long, press increasingly on the attention of all true 

 lovers of science.
