as Quinqueloculina agglutinans, Polystomella striato-punctata, No- 

 nionina depressula, Rotalia Beccarii, Trochammina injlata (abun- 

 dant), and Globigerina buUoides (one specimen). These often pre- 

 sent modified shell-structure, and are evidently the remnants of sea- 

 born families, left to struggle with the adverse influence of fresh 

 water, herein reminding us of the marine Crustacea found in fresh- 

 water lakes in Norway, and of other like instances. 



Mr. G. S. Brady supplies a suggestive paper on Naturalists' Field- 

 Clubs and their objects, giving some statistics as to half-a-dozen of 

 the best, comparing some of the different methods of research 

 adopted, and concluding with a well-urged plea against the destruc- 

 tion of small birds by the farmer, even for his own sake, and against 

 the extermination of rare plants by curiosity-hunting botanists, for 

 science-sake. Very valuable papers and notes on meteorology (Mr. 

 Atkinson), flowering-time of plants (Mr. G. S. Brady), entomology 

 (Mr. Bold), &c., complete this rich volume of natural-history facts 

 collected by the men of Northumberland and Durham.
