H. rufescens. Common. 



H. Caperata. Locally abundant. 



H. rotundata. Common. 



II- pi/gmoea. Three examples were taken in Maple Dean Clough, by 

 Mr. Cash. This species is often overlooked on accoimt of its minute size. 



H. pulchella. Wellhead ; King Cross and Norland. 



Cochlicopa lubrica. Common. 



Achatina acicula. A dead example in Maple Dean Clough, some

There are but few old people whose daily labour have kept them much 

 in the open air, who have not some pet theory about the dependence of 

 the weather upon the moon, or stars, or some celestial phenomena. Now, 

 it is not, perhaps, saying too much to assert, that there is not the slightest 

 foundation for the almost universally assumed relation between the 

 weather and the changes of the moon. This is the result of careful 

 scientific observations extending over a long series of years. It is enough 

 to refer to the labours of Arago, Toaldo and Schiibler, in support of this 

 assertion ; and those who wish to see how the observations were conducted 

 and the results obtained, will find a useful summary in Dr. Lardner'a 

 " Weather Prognostics." 



Other observers, with some claim to scientific training and careful 

 research, have endeavoured to forecast the coming changes of the atmo- 

 sphere by the variations of the barometer alone. That this is far from 

 satisfactory the result of repeated endeavours has fully shown. 



Others again, long familiar with the fearful storms of the Indian and 

 Chinese seas, accustomed daily to take accurate scientific observations both 

 meteorological and astronomical, have striven to connect the great dis- 

 turbances of the atmosphere with the position of the moon in her orbit m 

 relation to the earth we inhabit. This is called the Lunar Theory, and as 

 propounded by Mr. Saxby in late years, is known under the title " Saxby'a
