captured a number of flies, yet the webs seldom contained more 

 than one or two flies; and sometimes the webs were entirely 

 empty. One morning I saw a spider carry a fly down the gal- 

 lery and drop it on the sand below. This led me to examine 

 the sand in all my arachnaria. Upon the sand I found the re- 

 mains of a large number of flies. Although I did not observe 

 my spiders take but one fly and place it on the sand, yet the 

 facts seem to warrant the conclusion that the spiders remove 

 dead bodies from their webs. I do not, however, believe that 

 the observed facts warrant the conclusion that they are always 

 conveyed down the gallery. Indeed the location of many of the 

 flies seemed to indicate that they had been carried to the edge 

 of the web and dropped over.

 I. 



A Case of Absent-mindedness. A tame raccoon, which 

 has been observed for some time, still has the habit of washing 

 its food. On several occasions food was given him when hun- 

 gry, in such small morsels that on the way to his water pan he 

 devoured it completely. He c )ntinued toward the pan and 

 assumed the customary position before observing that he no lon- 

 ger had anything to wash This was repeated several times 

 until he seemed at last to " recollect himself," as we say, and 

 the small fragments were no longer carried toward the water. 

 This simple and probably familiar observation indicates a simi- 

 larity between instinctive and habitual processes of some inter- 

 est in forming opinions upon instinct.

Logical Inference in a Dog. The following incident 

 related by T. H. Pritchard, was kindly communicated by Pro- 

 fessor G. W. Manly. From a personal letter to the latter we are 

 permitted to quote as follows :

Prof. G. W. Manly : The facts about the dog are the 

 following : Some fifteen years ago I was hunting in Wake Co.,
