DEAN AND JACKSON : CHARA AND SHELL-MARL AT HAWES WATER. I5I 



To investigate thoroughly the exact area of these deposits, it would 

 be necessary to be on the spot more often than was possible for us, 

 in order to examine the various drains which are cut through the peat 

 and deposit periodically. We were fortunate on one occasion in being 

 there when one of these was cut, and observed the junction of the peat 

 and marl. This was very clearly defined, there being no gradual pas- 

 sage of the one into the other, as might be expected. 



No doubt much remains to be done as regards ascertaining the 

 number of species in the deposit, its depth, and the probable time 

 taken in forming it ; but these are more or less geological matters, 

 and would not, therefoie, come within the scope of this Journal. 

 Notwithstanding this fact, we hope to pursue our investigations still 

 further, with a view to elucidating one or other of these points. 



Regarding the living shells of the district, we are hoping to publish 

 a list in due course, including a general survey of the moUusca of this 

 region, using Morecambe as a base from which anyone conchologically 

 inclined might profitably make excursions. 



We will now conclude by tendering our best thanks to those who 

 have helped us to make this paper as complete as possible. More 

 especially are we indebted to Mr. R. Welch for aid in the preparation of 

 the block for illustration ; to Mr. C. Oldham for the identification of 

 doubtful Pisidia ; also to Messrs. R. Standen, A. S. Kennard, and J. 

 Postlethwaite, secretary of the 'Keswick Literary and Science Society, 

 for their kind advice and assistance.
