struction of the insects appear to be so general, that we may almost 

 renounce the idea of any chance discovery of perfect insects, even of 

 fragments sufficiently distinct to allow us to form a satisfactory 

 opinion on the general entomology of the Dorset Purbeck period. 



In like manner, there is also so great a general coincidence between 

 the insects of the Lower and those of the Middle Purbecks, including 

 those from the Ridgway quarries (judging, as well as I am able, from 

 the comparative paucity of materials which I have examined), that I 

 can come to no other conclusion, than that the insects discovered in 

 all these different strata belong to one general insectal fauna.
