MEETING 



Held on the 21st of November, 1906, at 2o Hanover Square, W. 

 A. N. Disney, Esq., M.A., B.Sc, Vice-President, in the Chair. 



The Minutes of the Meeting of the 17th of October, 1906, were- 

 read and confirmed, and were signed by the Chairman. 



The List of Donations to the Society (exclusive of exchanges and 

 reprints) received since the last Meeting, was read, and the thanks of 

 the Meeting were voted to the donors.

 Wright, Sir A. E., The Principles of Microscopy .. .. The Publishers. 



An Old Microscope by Dollond , .. Mr. Chas. Lees Curties. 



A Culpeper Microscope Mr. Wynne E. Baxter. 



With reference to these donations, the Chairman called special atten- 

 tion to the book, " The Principles of Microscopy," which had evidently 

 been written from a rather unusual point of view. It was illustrated 

 by coloured plates, and looked like a book of more than ordinary interest. 



Mr. C. F. Rousselet read a description of the two Old Microscopes 

 presented to the Society — one being an original Culpeper Microscope 

 by the Treasurer, and the other an old Cuff Model, made by Dollond, 

 by Mr. C. L. Curties — and observed that the last named possessed a 

 handle, a feature recently brought out again as a novelty. 



The thanks of the Society were voted to Mr. Rousselet for his com- 

 munication. 



Mr. Conrady said it was interesting to note in these two old Micro- 

 scopes the large size body-tube in the Culpeper form and the handle to 

 the Cuff pattern — -both of which things had been recently revived as 

 improvements to modern instruments by Messrs. Zeiss. 



Dr. Hebb exhibited a new porcelain filter made by Messrs. Doulton, 

 of Lambeth. It had been carefully tested by Dr. Bullock and Dr. Crau, 

 and found to be quite equal to the Chamberland filter. It was suitable 

 for laboratory work and also when fitted on taps for domestic purposes.
