I have now given you, in as plain a manner as 1 can, the 

 result of my further observations ; I invite other lovers of the 

 science to test their truth ; I shall be most glad of any 

 corrections their greater experience and better skill may 

 afford ; at any reasonable notice I will send to any of your 

 readers, a stock of specimens. The best I obtain are from 

 Branksea Island— Poole Harbour: the best specimens to 

 examine are those with the lightest green endochrome, and 

 in which the furroios are most marked. I am so engaged 

 I will not at this time put forth my theories in connection 

 with this Desmidium, for I could only do so in a hasty 

 and crude manner. I can with truth say, that I am more 

 than ever convinced that the microscope has not yet shown 

 me any object so beautiful, so wonderful, and which has so 

 amply repaid all the trouble I have bestowed upon it. 



I would only now add an invitation to brethren of the lens 

 to try their skill, and the power of their instruments on 

 Euastrum Didclta ; they will, if I am not mistaken, find in it 

 wonders, which, when developed, may rival my pet C Lunula.
