to the microscope would form a very good illuminator for opaque objects. 

 For those persons who could not comfortably use the binocular dissecting 

 microscope, he should recommend the use of a large spot lens as an 

 illuminator, which they would find of great use in showing the relative 

 positions of the various portions of a semi-transparent substance viewed by 

 transmitted light. 



The President having proposed a vote of thanks to those gentlemen who 

 had so kindly sent specimens of dissecting microscopes that evening in 

 illustration of the subject they had before them, it was put to the meeting, 

 and carried unanimously. 



Dr. Matthews said he was rather taken by surprise at the proceedings 

 having terminated so abruptly, but rose to do what he had intended to have 

 done earlier, namely, to propose a hearty vote of thanks to their President 

 for the very interesting communication which they had heard that evening. 



The motion was put to the meeting, and carried by acclamation. 



The President made the usual announcement of meetings, &c, and the 



proceedings closed with a conversazione, at which the following objects 



were exhibited : —
