PROCEEDINGS OF THE SOCIETY. 
353 
Dr. Hebb said a letter bad been received from Mr. T). Bryce Scott, 
in which he remarked that he had seen Mr. Dur rand’s paper on the 
Foraminifera of the Malay Archipelago, and said that if any Fellow of 
the Society was interested in the subject and would like to have some 
West India dredgings, he should be very pleased to supply them. 
The President said that when the Fellows of the Society received 
their copies of the Journal for April, they would find, as a frontispiece, 
a very excellent portrait of the late Mr. Hugh Powell. He was well 
known to the Society, and would be remembered by many of the Fellows. 
He also had great pleasure, on behalf of the Society, in asking Mr. 
Thomas Powell’s acceptance of a framed proof copy of this portrait of 
his father. 
Mr. Thomas Powell expressed his sincere thanks to the Society for 
the gift. 
Dr. Hebb said he had been asked to mention that the Ray Society 
was in want of an additional number of members at the present time. 
If any of the Fellows present were inclined to support this Society, it 
would be conferring a great benefit upon science generally. 
The President said that as they had been disappointed in not hearing 
Dr. Beale’s paper, and there being nothing else to bring before the 
Meeting, he would make a few remarks upon the theory and construc- 
tion of eye-pieces for the Microscope ; in the course of which he de- 
scribed a new eye-piece of his own invention, which he now introduced 
for the first time to the notice of the Fellows. He then proceeded to 
explain the subject by means of diagrams upon the board. 
Mr. Sebastian Davis said there seemed to be a great diversity of 
opinion as to whether or not it was better to use an eye-piece in taking 
photomicrographs of low-power objects ; and he wished to ask the 
President if he considered that this new form of eye-piece of which 
they had just heard the description would be of any use in delineating 
objects on a space of 3 inches square. 
The President thought that for projection purposes it was generally 
better to use an eye-piece rather than none, except for quite low-powers 
such as the new Planar. He had not tried the new form of eye-piece 
in this way, but he did not think it would be of much service for this 
purpose. 
Canon Carr inquired if a compensating eye-piece would be of any 
use for this purpose. 
The President said that in the compensating eye-piece they had an 
over-corrected combination to meet the under-correction of apochromatic 
object-glasses; when he tried apochromatic objectives with a common 
Huyghenian eye-piece he found they did not give so good an image. 
The President proposed that a very hearty vote of thanks be given 
to Messrs. Beck, Powell, and Curties, for kindly cleaning the old object- 
glasses in the Society’s Cabinet — all of which were in consequence now 
in first-rate condition.
