Meteorological Observations. 223 



in this, have thought these notes, made with the living animal before 

 me, might perhaps be worth the room they occupy, more especially 

 as the Argulus seems to be very little known as a British species. 

 From what has been stated it would seem to be very tenacious of 

 life. The individual here treated of is the second Irish one I have 

 seen ; the other was, when swimming freely in Lough Neagh, taken 

 by Mr. Hyndman in the autumn a few years since. Like the present 

 specimen, it displayed a mass of large ova. 



INFUSORIAL ANIMALCULES IN RED SNOW. 



Mr. Shuttleworth relates, that being occupied in the examination 

 of some red snow that fell at the Grimsel, and expecting to see only 

 inanimate globules of Protococcus nivalis, he was astonished to find 

 that it was composed of organized bodies distinct in nature and 

 form, partly vegetable, but the greater number endowed with the 

 liveliest powers of motion, and belonging to the animal kingdom. 

 Among these he has named one species Astasia [Ehrenb.] nivalis, 

 and another Gyges sanguineus . — Bibl. Univ.
