PROCEEDINGS OF THE SOCIETY. 411 



Mr. Nelson said, that having had the pleasure of examining this Micro- 

 scope, he could only say that its working seemed to be exceedingly perfect. 

 As the fine adjustment was placed just behind the body, the limb could 

 be made of any length without causing any additional strain upon the 

 screw — a matter which would be of very great advantage in the case of 

 Microscopes which were made for examining sections of very large size. 

 The thanks of the Society were voted to Mr. Nelson and to the author 

 of the paper. 



The President said most of those present in the room had no doubt 

 seen something of the very excellent show of objects illustrating pond 

 life exhibited that evening. In securing so large a number of exhibits 

 of this class they were greatly indebted to many Members of the Quekett 

 Microscopical Club who had brought their Microscopes and objects for 

 the purpose. He was sure the service thus rendered would be much 

 appreciated, and he had therefore great pleasure in moving that the best 

 thanks of the Society be given to these gentlemen for so kindly exhibit- 

 ing on that occasion. 



The motion having been put from the Chair, was carried unanimously. 



The President, in announcing the adjournment of the Meeting until 

 Wednesday, June 20th, said he hoped then to be able to submit and 

 explain a series of lantern slides representing minute structure of some 

 Palaeozoic plants. He feared, however, that in his present state of health 

 he was somewhat bold in undertaking to do this, but hoped that by the 

 time named he would be more equal to the undertaking than was unfor- 

 tunately the case at the time of s£>eaking.
