Dr. G. H. Broadbent described microscopical observations 

 he had recently made on the development of a rotifer existing in 

 an infusion, made in January last, of the mud deposited on his 

 bicycle. On Friday, the 2nd inst, the organism was found, and 

 on the 4th the ovum was extruded, and was under observation 

 until the 6th, when it was lost. On the 7th instant another was 

 found, and the stages of development observed day and night, 

 with only seven hours intermission, until the nth, when it 

 emerged from the ovum fully formed. His communication was 

 illustrated by a number of diagrams. 



A paper by Mr. Peter Cameron was read, entitled 

 " Description of a New Genus and Species of Hymen- 

 optera from Chili." 



This paper will be printed in full in the Memoirs. 



Dr. J. Lawson Russell, of Todmorden, then read a paper, 

 entitled "Vestiges of Primitive Man found near Tod-
