cies, and a most accurate judgement to discriminate one varying 

 form from another. But though Algae were the natural objects in 

 which of late he chiefly delighted, he had a very extensive know- 

 ledge of marine zoology, and has made large additions to the Irish 

 fauna. Born in very humble circumstances, imperfectly educated, 

 and always with narrow means, he had to struggle through life with 

 many hindrances to progress. That he overcame many of these 

 hindrances is a proof of his talents and energy ; that he did not 

 overcome all may well be forgotten by those who have not had to 

 struggle with any, and yet do not fear to criticize the short-comings 

 of others. Mr. W. MacCalla fell a victim to cholera in May 1849, 

 aged about 35."
