IMr. Curties said that the greatest objection to this class of nose-piece 

 was its weight ; but he understood from Mr. Ingpen that in the form he had 

 described, the weight was much lessened. 



Mr. Hainworth thought the objection was not so much against the weight 

 of the nose-piece itself, as the weight of the objectives which it carried. 



Mr. Ingpen said of course if there were heavy objectives screwed into it, 

 the weight would take the centering out of any slow motion. 



Dr. Matthews thought the chief value of such a piece of apparatus was 

 to use it first as a finder, with as low a power as possible, and then to pass 

 on to higher ones — in such cases its use was invaluable. 



Mr. Hainworth considered that it was also of great use in comparing two 

 objectives by different makers. 



Announcements of meetings and excursions were then made, and the 

 proceedings terminated with a converzatione, at which the following objects 

 were exhibited : —
