MICRO-ZOOLOGY AND BOTANY OF ASKERN. 



Rev. FRANCIS H. ALLEN, 



I'icar of Moss, near Askern. 



The ponds, ditches, and drains which abound in this neighbourhood 

 are simply teeming with microscopic hfe ; but, alas, in this out-of-the- 

 way place, with only a |--inch objective and no library of reference to 

 assist me, it is quite impossible for me to follow the example of my 

 forefather, and name every individual that comes under my observa- 

 tion. Before, however, giving a list of those T have succeeded in 

 identifying, I should like to remark that never during the twelve years 

 that I have resided in these parts have I come across a living Meli- 

 ce7'ta^ though I have found their cases without number. Why is this'? 

 I have searched for them at all times and seasons. Secondly, although 

 most of the objects now to be enumerated are distributed pretty 

 plentifully throughout the district, yet certain of them seem confined 

 to special habitats. My list is as follows : — 



Confervoidese. — Batrachospernnun (Haywood andWrancar Drain), 

 Botrydi?ia vulgaris, Coccochloi'is brelnsso7iii\ Spirulina jenneri, Sphv- 

 gyra, Ulva bullosa, Volvox globato?' (abundant, Thorpe Brickyard 

 Pond, disused). Desmidiacese. — Cosinarium margaritiferum (Askern 

 Pool and effluent drain), Closteriuvi (Haywood and Wrancar Drain),
