sufficient power to be assured on this point. The fact of these 

 delicate markings being almost entirely obscured by moisture 

 appears to me remarkable, and calculated, if investigated by 

 experienced microscopists, to throw much light on a subject 

 still I presume involved in obscurity, namely, the precise 

 nature of these markings. I may observe that I have 

 another slide of the Pleurosigma angulatum, in which, from 

 the same cause, the phenomenon is very visible. — G. Hunt, 

 Birmingham. 



Notes to Mr. Currcy'a Paper on the Threads of Trichia. — The 



following misprints occur in this paper. At p. 20, the word 

 " accurate" is printed instead of " arcuate," which renders 

 the sentence unintelligible. In two places Trichia is printed, 

 where the word should be Trichirs, and in one place Arcyria 

 is printed instead of Arcyri®. — Frederick Currey.
