in healthy yet, though almost confined to his sofa, he never 

 ceased to work. 



Of the collections left by Gould the Humming-birds form 

 the largest and most important part ; but in addition to these, 

 the subjects of most of his other monographs are well repre- 

 sented. The whole of these have been offered by his repre- 

 sentatives to the Trustees of the British Museum for a 

 moderate sum, and, we are glad to add, have been purchased 

 for the national collection. The collection formed in Aus- 

 tralia, it will be remembered, was lost to this country, and 

 is now in America, in the Museum of the Academy of Natural 

 Sciences of Philadelphia.

Mr. E. R. Alston. — The untimely death of our friend and 

 fellow-worker Edward Richard Alston, which took place at 

 his rooms in Maddox Street on the 7th of March last, leaves 

 a vacancy in the thin ranks of the workiug naturalists of 

 this country that will not be easily filled up. At the time 

 of his decease Mr. Alston was Secretary to the Linnean So- 

 ciety, a member of the Council of the Zoological Society, and
