Mr. Poulton's notes in 1885 upon 



IV. A pupa of S. ocellatus threw off the larval skin upon 

 the pan of the balance, so that the immense loss of 

 the first minutes was obtained : — 



In this case the immense early loss is more nearly 

 obtained than in any of the previous cases, but it is not 

 all recorded here, because there is a great loss during 

 the process of throwing off the larval skin. Never- 

 theless, the loss was extremely rapid during the first 

 hour in which the pupa was weighed, as a comparison 



* The pupa turned over and thus exposed its ventral surface 

 more freely. 



I Damp but not raining; rained yesterday, 



I A very damp day. 



§ Very damp, and yesterday also.
