limit in Yorkshire, though, it is by no means to be assumed that 

 such will be the case when some portions of southern and south- 

 western Scotland come to be more carefully examined ; the writer 

 of this believes that many will be found to extend to that part of 

 Scotland though skipping the northernmost counties of England. 



In a few instances the author has not availed himself of the full 

 material at his command, notably under Oeranium nodosum {^. 179) 

 and Carex Gibsoni (p. 465), yet he quotes Borrer's lierherium at 

 p. 344, presumably seen by himself (vide explanation of Flora). 



For the Batrachium Ranunculi Dr. Lees constructs a " schema " of 

 his own, although he has arrived " at a profound conviction of the 

 truth of the grouping given by Sir J. D. Hooker in the third edition 

 of the ' Student's Flora.' " 



Whatever Dr. Lees's var. incumhens of " Ficaria verna" may be, 

 the plant of Boswell-Syme is certainly not a hybrid of the usual 

 form with Caltha palustris. 



Under Hieracium Gibsoni the author observes " this has yellow 

 styles, and it runs into H. maculatum ; it is clearly allied to H, 

 ccesiwm." After having H. Gibsoni growing for some years along 

 with IT. vulgatum var. maculatum and others of the genus the 

 writer demurs to this, and would say that it keeps perfectly 

 distinct and can be picked out by its seed-leaves alone from macu- 

 latum &c. He also gives the H. maculatum of Smith as a synonym 

 of vidgatum var. macidatum of Backhouse ; according to Syme, in 

 ' English Botany,' this is not so, as Backhouse named specimens of 

 Smith's plant— "var. nemorosum of vulgatum." 



Lender Potamogetum pusiUus " var. rutilus, Wolfgang," the 

 description of this supposed plant will easily apply to forms of 

 pusillus ; the true plant of Wolfgang is rare, and many specimens 

 so named are not it ! 



One query suggests itself at the last : Are not our Floras be- 

 coming too bulky ? If Cryptogamic botany still advances with the 

 rapid strides it has done lately it will become a matter of considera- 

 tion whether it would not be well to publish- the Cryptogams as a 

 volume. Abthur Bennett.

The whole of this number of the Bulletin is occupied by a paper by 

 John C. Smock on the " Building Stone in the State of New York." 

 The rocks are arranged as I. " Crystalline," and II. " Subcrystalline 

 and Fragmental." The former comj)rise 1. Grranites, syenites, 

 gneisses, mica-schists ; 2. Trap-rocks ; 3. Marbles, serpentines. 

 The latter have 1. Quartzytes [s«c] and sandstones ; 2. Limestones; 

 3. Slates ; and these are arranged in geological groups, all except 

 some " New Red Sandstone " belonging to either the Silurian or 

 the Devonian formation. The geological position and geographical
