trusted tliey would accept his assurance tliat both the gift and tlie 

 feeling which had prompted it would be very highly valued by 

 him. 



Mr. C. L. Ciirties exhibited Leitz's projection microscope, and 

 explained the method in which it was employed, both for 

 photography and for the drawing of objects placed upon the stage. 



The Chairman thought this appeared to be a useful and handy 

 arrangement, and one which certainly possessed considerable 

 novelty. The sketching table scarcely looked as if it was very 

 conveniently arranged, although for rough purposes it might 

 answer fairly well. He did not know whether it would be found 

 useful also for delicate objects. 



Mr. Karop exhibited and described a new biological microscope 

 brought out by Mr. Swift, which was much the same in general 

 design as the one he brought out a short time ago, but it had been 

 greatly improved in the matter of steadiness by the alteration in 

 the foot, in which it would be seen there was now a double support 

 at the back ; this double leg being pivoted to the body would 

 readily adapt itself to any surface upon which it was placed. 



The Chairman said this double hind foot was certainly a novelty, 

 and though it gave the idea at first sight that it would be less 

 likely to be steady than one which rested upon three points, yet 

 tlie way in which this was fitted seemed to give it the advantage 

 of the steadiness of a tripod without its liabilityto tilt. 



The thanks of the Club were voted to Mr. Curties and Mr. 

 Swift for sending these instruments for exhibition. 



A paper by Mr. E. M. Nelson, " On the Determination of the 

 Foci, etc.," was taken as read, and on the motion of the Chairman 

 a vote of thanks was passed to the President for his communica- 

 tion, which would be found very instructive when printed in the 

 Journal. 



Mr. H. W. King read a paper on " Amoeboid Attributes. ' 



Mr. J. D. Hardy was glad that a paper had been read which 

 treated of pond life from a histological point of view. With 

 reference to this paper the main points appeared to be the abnormal 

 elongations or projections of the pseudopodia of these West Indian 

 Amoebas and the specialized "attributes"' given to the protoplasm. 

 The pseudopodia were described as being composed entirely of 

 ectosarc ; this implied a power at the will of the creature to 

 differentiate its protoplasm, a theor^y which could hardly be accepted
