The thanks of the Club were unanimously voted to the donors. 



The Chairman then called upon Dr. Hudson to favour them with his ex- 

 planation of the subject of the illumination of Rotifers on a dark field. (An 

 abstract of this communication will be found at p. 164.) 



The Chairman expressed his regret that their President had not been able 

 to be with them on that occasion, for no one who had not made a complete 

 study of these organisms could do complete justice to the subject. Dr. 

 Hudson was one of their best authorities on Rotifers, and was, at the same 

 time, one of the clearest demonstrators he had ever had the pleasure of 

 listening to, while his method of illustration could only be characterised as 

 accurately beautiful and altogether superb. He had the greatest pleasure 

 in proposing a vote of thanks to Dr. Hudson for his very admirable lecture, 

 and for his kindness in coming all the way from Bristol to deliver it, and 

 to show them his very beautiful diagrams. 



The vote of thanks having been put to the meeting and carried by 

 acclamation, 



The Chairman called upon Dr. Matthews to give an explanation of the 

 Micro-Megascope, a new method of showing microscopic objects, irrespective 

 of size. (See p. 167.) 



A vote of thanks to Dr. Matthews was unanimously passed, the Chair- 

 man observing that he was sure they would welcome anything which added 

 to the enjoyment of the microscope, even if only in a toy form. 



Mr. J. D. Hardy thought that, in the interests of the Club, he ought to 

 mention that Mr. Jas. Smith had, he believed, exhibited an identical 

 arrangement, or certainly one very much like it. He had shown it at his 

 i the speaker's) house, and also at the Hackney Microscopical Society, but 

 he did not claim it at all as his original idea, but, on the contrary, he said 

 he got it from some Amei'ican paper. He certainly was enabled to show 

 transparent objects as well as opaque ones, and was able to diminish them, 

 and also to magnify them up to a half -inch objective. It was just possible 

 that Dr. Matthews might have hit upon some improvement upon it, and he 

 only regretted that Mr. Smith was not present to speak for himself. He 

 thought, however, that for the credit of the Club he ought to mention that 

 the idea was not a new one. 



The Chairman said that it was quite right and necessary in the 

 interests of science that priority of discovery should be frankly
