Since furnishing you witli a report of the proceedings of this 

 Society, up to the time of its anniversary in February last, we 

 have had several excellent meetings, and many interesting excur- 

 sions in search of microscopic objects. 



On ]March 5th Mr. B. Proctor read an elaborate and excellent 

 paper, " On Micro-chemistry." On April 3rd, Mr. John Brown, 

 " On the Structure and Modes of using the Microscope, and its 

 various appliances." On June 4th, the Secretary explained the 

 principal objects of interest to be found on the sea coast near 

 Tyuemouth.

 Microscope;" after which a warm discussion ensued, '• On the 

 Kelative Value of the Monocular and Binocular Microscopes." 



September 2nd : Mr. B. Proctor read a valuable paper " On 

 Binocular Vision and the Binocular Microscope," towards the 

 close of Avhich he introduced arguments for the pm*pose of 

 showing that the Binocular Microscope, when used with high 

 powers, exaggerates the real elevation of microscopic objects. 



September 25 : eighteen members of the Newcastle Microscopical 

 Society attended with microscopes at the Microscopical Soiree, 

 in connexion wdth the Sonth Shields Mechanics Institute. There 

 were thirt}'-six microscopes exhibited, and much interest was 

 manifested by a very large and respectable audience. There is 

 every prospect of a Microscopical Society being foi'med in con- 

 nexion with the institution. 



Tuesday, October 1st ; Mr. Martiu, an amateur optician, de- 

 livered a lecture on " How to make a Binocular Microscope." 

 He exhibited a large and very elegant ''nstrument of his ow;i 

 construction, made after the pattern of Boss' best, on the 

 Binocular principle. ISIuch interest was exhibited in contrasting 

 the powers of one of Smith and Beck's Monoculars with Mr. 

 Martin's Binocular.
