OF THE 



QUEKETT MICROSCOPICAL CLUB. 



At the meeting of the Club held on October 24th, 1911, Prof. 

 E. A. Minchin, M.A., F.R.S., President, in the chair, the minutes 

 of the preceding meeting, held on June 27th, were read and con- 

 firmed. 



Messrs. H. G. Brierly and O. W. Downing were balloted for 

 and duly elected members of the Club. 



The list of donations to the Club was read and the thanks of 

 the members voted to the donors. The Hon. Secretary drew 

 particular attention to a small microscope which had been pre- 

 sented to the Club by Mr. Hugh Paterson, of Sydney, N.S.W. 

 This microscope had been given to the donor's father in 1850 

 by Prof. J. T. Quekett, F.R.S., M.R.C.S., the distinguished 

 microscopist from whom the Club takes its name. 



The Hon. Secretary read letters of thanks from M. C. Cooke, 

 M.A., LL.D., A.L.S., in acknowledgment of the resolution passed 

 at the previous meeting ; also from the Misses By water, for the 

 vote of sympathy passed at the same meeting on the death of their 

 father, Mr. W. M. By water.

 read by the Hon. Secretary. The author said that this micro- 

 scope, which supplies three steps in the evolution of the modern 

 instrument, was brought to his notice by Mr. T. Court. The 

 instrument is figured on a plate in a pamphlet : " A Description 

 of the Compound Microscope, with great improvements, London, 

 made and sold by James Mann, at the sign of Sir Isaac Newton's 

 Head and Two Pair of Golden Spectacles, near the west end of 

 St. Paul's, 1751," which accompanies it. It is, in the main, 

 obviously a copy of J. Cuflfs (1744), the improvements consisting 

 in the mirror and its attachment, and in making the instrument

 George Adams in 1746, and in the instrument now described we
