40 THE MICROSCOPE. Mar., 



truraent is now perfect, and that consequently the most 

 important raison d'etre of the Society was over ; he by 

 no means agreed in that view ; he believed that there 

 was as much scope for progress in the future as there 

 had been in the past. It was not by any means the first 

 time that this idea had been put forward. In 1829, Dr. 

 Goring, then a great authority on the subject, wrote in 

 one of his published works, "Microscopes are now placed 

 completely on a level with telescopes, and like them, 

 must remain stationary in their construction." In 1830, 

 less than a year after, appeared Lister's epoch-making 

 paper, "On the Improvement of Achromatic compound 

 Microscopes," and we have been improving ever since.

A New Peritrichan Infusorian. 



BY T. B. REDDING, 

 NEW CASTLE, IND. 



On the I7th of January, 1895, I found, on a filament of 

 Vaucheria sessilis growing in a jar, in my green-house, 

 where it had been at least eighteen months past, an In- 

 fusorian entirely new to me, though I have studied the 

 Infusoriaus for more than ten years past and made hun- 

 dreds of drawings of them. 



I refer it to the order Peritricha Stein ; sub-order, 

 Sedentaria ; sub-family, Vaginicolinae ; Genus and Spe- 

 cies, doubtful. 



The lorica is sessile, of a pale brownish color and 

 membranous. Length of lorica 1-216 ; width 1-700 ; 

 neck of animal, when fully extended, as long as body, or 

 lorica, or nearly so ; diameter 1-1,600 ; length of cilia 

 various, from 1-700 to 1-900 inch ; with two much long- 

 er. Opening of lorica 1-1050 inch wide. 



There were two animals in same lorica, but whether 

 united or not I could not determine, but I think not.
