ON THE HUSK, OR HOOSE IN CATTLE. iSa 



Rossia palpehrosa. — A new molluscous animal, described 

 and figured by Mr. Owen in a manner that leaves nothing to 

 be desired. The description has afforded us great pleasure ; 

 it is too long to extract, and too concise to abridge ; we 

 therefore entreat such of our readers as may possess a taste for 

 anatomical detail to study the masterly production. 



Limarina Arctica. — *' A very abundant species, peopling 

 as it were the Polar seas, and constituting the chief source of 

 subsistence to the Greenland whale. It is indeed most truly 

 wonderful that so small and apparently insignificant an animal 

 can be made to fulfil the most important purposes : from the 

 smaller species of Crustacea to the enormous whale all derive 

 their food directly or indirectly from this little creature. It is, 

 in fact to the inhabitants of the Arctic ocean what the vegetable 

 kingdom is to the inhabitants of the land — the foundation of 

 animal existence." 



We have no space for further notice of this interesting work ; 

 we can only by this slight sketch hold out the example of these 

 accomplished and enterprising voyagers to those of our fellow- 

 countrymen, who have fortune and leisure at their command.

Sir, — As you considered a former letter on the subject of 

 this most extraordinary disease of sufficient importance for in- 

 sertion, and as several other papers copied it into their columns, 

 perhaps some further particulars attending it, which have come 

 under my observation, may not be uninteresting to some of 

 your readers, and may tend to afford or elicit from others ad- 

 ditional information as to the cause and cure. 



In that letter I stated that on examination of the weaning 

 calves which had died, I found the disease to arise from worms 



the windpipe and lungs^; that it prevailed to a considerable
