PROCEEDINGS OF THE SOCIETY. 
The President said that they had received a very important paper 
upon blood-corpuscles, which, however, it was impossible to read in 
extenso, especially as it was illustrated by numerous drawings, apart 
from which it could not be very readily understood. Mr. Stewart had, 
however, carefully read the paper, and would give them a rhume of 
its contents, and the paper itself would appear in full in the Journal. 
Mr. Stewart said that the paper in question was in continuation 
of one formerly read before the Society upon blood-corpuscles, and 
which was already in print. They would probably remember that the 
author (Dr. H. D. Schmidt, of New Orleans) then described his obser- 
vations upon the blood of man, and he now proceeded to follow 
this up by some further remarks, and to make comparisons between 
what he had seen and the blood of the Amphiuma, frog, and of man. 
Mr. Stewart then, by means of drawings on the black-board, described 
the chief points of the paper, and indicated the line of argument taken 
and conclusions come to by the author. 
The President proposed a vote of thanks to the author of the 
paper, and also to Mr. Stewart for the very excellent description 
which he had given of it. Carried unanimously. 
The President called attention to the Scientific Evening which it 
had been arranged should be held on the 15th instant, and urged upon 
the Fellows the desirability of their bringing up their instruments 
with any objects of interest upon the occasion. He hoped that no 
effort would be wanting to secure a good attendance and make the 
meeting a success. 
The President said that it had been thought that their ordinary 
meetings might be made more interesting if, after the papers had 
been read, the Fellows would bring forward any notices of objects 
of interest which might have come before them, or of any matter 
relating to their microscopical pursuits upon which it might be de- 
sired to obtain any further information. With a view of setting the 
example, he would just mention two little matters which might serve 
to start this plan amongst them. He believed that at the present 
time specimens of the very beautiful Lissajou’s curves, drawn micro- 
scopically by Mr. West, could be obtained, and he would strongly 
advise Fellows who were interested in the matter to get them, with 
a view to the solution of some curious questions of interpretation. 
If they procured a specimen of these curves in which the lines crossed 
one another more or less obliquely, and began to examine it with a 
4-inch objective, illuminating it with a larger spot lens than usual, 
they would get some very beautiful effects of colour, but they could 
not obtain a really correct view of the object itself, because of the 
very striking character of the false perspective, which made it seem 
as if one set of curves passed a long way behind the others. It seemed 
to him that, if they met with any similar arrangement in nature, they 
would not be able to detect the fallacy, except by some process of 
reasoning from analogy. He should advise that these objects be ex- 
amined by various powers up to inch, and was sure that some very 
instructive results would follow. With this power they did not get 
at all a true idea of the object, but they did obtain a still more curious
