The thanks of the Club were voted to the donors. 



The Secretary said he had received a letter announcing the formation of a 

 new Natural History Society at Watford, and asking him to bring it before the 

 notice of the members of the Club, in order that any residing in that neigh- 

 bourhood might avail themselves of the opportunity of joining. 



The following gentlemen were balloted for, and duly elected members of the 

 Club :— Mr. Thomas Bolton, Mr. Edward Dadswell, Mr. F. W. Howard, Mr. 

 Henry Power, Mr. A. Tinney, the Hon. J. C. Vivian. 



The Secretary said he had received a letter from Mr. R. Sedgwick, Hon. Sec. 

 of the Tower Hill Microscopical Club, intimating that their Annual Soiree was 

 arranged to take place on Wednesday, February 17th, and asking for the co- 

 operation of the members of the Q. M. C. on that occasion. 



The Secretary called the attention of the members to a new Portable Micro- 

 scope exhibited in the room, which had recently been designed and made by Mr. 

 Moginie ; it was specially adapted for use with low powers. He always thought 

 that the 4-in. objective of Ross had not been done full justice to on account of 

 the small field of the A eyepiece. The new instrument had a large Huyghe- 

 nian eyepiece of a very low power, giving a splendid field of view, and the lenses 

 of the eyepiece were made to slide into the tube, instead of screwing in the 

 usual way, so that they could be readily removed for wiping. The focussing 

 was effected by a rackwork arrangement attached to the stage instead of to the 

 body of the instrument, which was fixed to the stand ; thus adding greatly to 

 the steadiness of the whole, and the rackwork was sufficiently delicate for use with 

 £ or even \ inch objective. If required for use in the vertical position, the 

 instrument could be screwed into a plate provided for the purpose on the lid of 

 the wooden case, into which the microscope and apparatus were arranged to 

 pack in a very small compass (12in. X 5 X 3£). 



The President said he had the pleasure of seeing an instrument of this kind 

 shewn by Mr. Moginie a short time ago at the Royal Microscopical Society, and
