jlum^aUAKrS PROCEEDINGS OF SOCIETIES. 191 
The Developmental Eelations of the Lower Fungi.— It is within 
the reach of all of our readers to make observations on this point. 
The subject is just now of the utmost importance ; and as moulds are 
as abundant as microscopes, we hope ere long to receive numerous 
communications on the relations of the different forms of Mucor. 
Dust as seen by tlie Microscope.— In a paper lately contributed 
to the Literary and Philosophical Society of Manchester (v/hose 
report, by the way, reaches us too late for insertion in this number), 
Mr. J. B. Dancer stated that he has been examining the dust of the 
air at different heights, and has established some important results. 
In every instance molecular activity was abundant; but the largest 
proportion of moving animal organisms and of vegetable structure was 
found at a height of about five feet from the ground. 
Diatomacese from Danish Greenland.— At the meeting of the 
Botanical Society of Edinburgh on the 14th of January, Professor 
Dickie gave an account of the specimens collected by Mr. Eobert 
Brown. All the species recorded were British, with the single excep- 
tion of Hyalodiscus suhtilis, originally described by the late Professor 
Bailey, from Halifax ; found also on the shores of North-west America, 
and now on the shores of Greenland. 
Chair of Botany in the Dublin College of Science.— This Chair 
has been filled by the appointment of Professor Wyville Thomson, of 
Queen's College, Belfast. Dr. Thomson's name is so familiar to all 
naturalists, that it is unnecessary to comment on his fitness for the 
office he now holds.

legibly — especially the technical terms — and by "underlining" words, such as
