Mr. Turner's Observation on a Spider. 43 



which may well deserve consideration. I have not observed any similar 

 feat recorded of Spiders in the volume on Insect Architecture in the 

 Library of Entertaining Knowledge. 



I believe that very little is as yet known of the great variety of Spi- 

 ders and their operations. From a comparison of the individual in 

 question with the very few figured by Donovan, it appears to be most 

 like the Aranea externa, vol. viii. p. 48. And as it is there said to be 

 always found upon trees, and never upon the ground, this may be the 

 reason why it has executed the arduous task of raising the branch on 

 which it was confined to the upper part of the glass. 



Mr. T. SopwiTH has obligingly furnished the Society with a drawing 

 of the glass and its content. {See Plate VIII.)
