On the Coloration of the Water of the Serpentine. By A. H. Has- 

 sall, M.B. [Mr. Hassall attributes the colouring of the water to a 

 confervoid plant, the Anabaina Flos-aquae of himself and Dr. Harvey, 

 and the Dolichospermum Thompsoni of Mr. Ralfs, but which he now 

 describes under a new generic name, Coniophytum Thompsoni.] 



Further Remarks on Fumaria Vaillantii and F. parviflora. By the 

 Editor. [It appears that two species of Fumaria occur in the vicinity 

 of Saffron Walden, growing intermixed, and both having probably 

 been distributed among botanists under one or other of these two 

 names ; the specimens more or less commingled together, and the 

 names therefore equally crossed.] 



A Monograph of the Hieracia; being an abstract of Prof. Fries's 

 'Symbolae ad Historiam Hieraciorum.' Continued from a former No. 

 [The species are here enumerated and partly described, though nei- 

 ther in a very clear, nor very satisfactory manner ; but whether this 

 may be the fault of the English translation, of the German abstract, 

 or of the original composition of Fries, would require careful collation 

 to decide upon.]
