bhere seem to be several varieties somewhat differing from either of tlie two; 

 and more or less intermediate between them. 



A third species, characterised mainly by an Ascus with 1'28 spores, or with a 

 still higher number, was met with by me at the same time, but it was crushed 

 under the microscope before I was aware of its presence, so that I only saw the 

 asci crowded with its almost uncountable spores. Mr. Broome thinks this is 

 probably the same with M. Boudier's Ascobolus duhiv.s, a species he thinks he 

 found near Bath. I will not trouble you with the characters of this species, 

 because they may yet be found under more favourable circumstances. 



Gentlemen of the Woolhope Club, botanists have no prejudices, and in truth 

 few objects are more charming when duly magnified than these minute plants. 

 Though their birthplace be repulsive they suffer not one tinge of corruption 

 their brilliancy shines quite unsullied even on their native filth, and like Marina 

 in the stews, they wear a halo of purity in the vilest dwelling-place.
