Mr. Karop exhibited a microscope designed by Mr. T. T. 

 Johnson, the chief point of novelty about which was the 

 ingeniously contrived screw adjustment for focussing the sub- 

 stage. He expressed a hope that a further improvement might 

 be effected by doing away with the heavy foot and the spring- 

 clips upon the stage. 



The Chairman entirely agreed with Mr. Karop as to the 

 extremely convenient form given to the substage movement 

 before them ; it was not only ingenious, but also likely to be 

 very useful. He agreed also as to the stage clips, which had 

 only one advantage, namely, the ease with which they could be 

 taken out. 



Mr. Karop said he should like to say a few words on one or 

 two small matters, as the agenda paper was not very full that 

 evening. Firstly, we may, as microscopists, be allowed without 

 pedantry to take cognizance of trifling things, and accuracy even 

 in non-essential concerns is desirable. Now English is a very 

 elastic language, and we often have to incorporate terms for 

 which we can find no equivalent ready to hand ; to this, of 

 course, there need be no objection. But latterly I have noticed 

 a word, for the introduction of which, under correction, I think 

 Mr. Nelson is responsible, and I see it has gained admission to 

 the new edition of " Carpenter," and against its furthur use I 

 would desire to raise a mild protest. I allude to the term hup or 

 loups, used chiefly in connection with Steinheil's formula for 

 aplanatic magnifiers, but also for other similar combinations. It 

 is a French word, the German equivalent being Uipe, plural 

 lupen, and in both it applies to any hand or pocket magnifier, 

 whether a single or compound lens, and therefore it should not 

 be restricted to one or two combinations. But it is unnecessary. 

 Why not speak of a Steinheil or other maker's triplet 

 as we do of a Wollaston's doublet, or add "magnifier" to 

 indicate the general use of such combination? 



In reading the chapter on mounting in the new " Carpenter " 

 I have come across two curious things which require notice,
