cannot agree with him; it is precisely this which appears 

 to me nol to he the question ! It is rather a question for 

 philologists^ not for botanists, least of all for bryolo- 

 gists. There is no need to repeat the argument so well put 

 by M, Venturi, but I should Hke to point out one result 

 that would take place were we to follow out Lindberg's 

 reasoning on this point ; namely in the case of plant- 

 names founded on the names of persons or places. Should 

 literary research show that such a name , as usually 

 received^ had undergone alteration in spelling some cen- 

 tury or so backj it would then be necessary to readjust 

 the spelling of the plant-name. For example, should an 

 old document be found showing that the family name 

 Sivartz had been originally spelled Schtvarz^ and through 



the laxity in spelling characteristic of old times had been 

 erroneously changed to Swartz, it would appear on Lind- 

 berg's reasoning that Swartzia must be dropped and 

 bryologists must get their works reprinted with this 

 genus of Dicranacese spelled Schwarzia, 



Dixon.

Sur les murs du pare de Vizille se voyaient autrefois 

 bon nombre de mousses, parmi lesquelles on remarquait 

 les Bar hill a riQida et Horschuchiana, mais un crepissaee 

 les a fait disparaitre. 



M. I'abbe Boulay , dans sa Flore dcs muscinees de 

 France, indique a la Mure, sans preciser davantage la 

 localite , le rare Brack ijthccium tracJu/pndUim ; cette 

 mousse, que j'ai recoltee et signalee au ' Grand-Veymont 

 (6c excursion) et au lac Coeurzet (9'' excursion), vient-elle 

 aussi au Seneppe? 



De la Mure a Corps, nous avons 25 kilometres a par- 

 courir. Au sortir de la Mure, soit que nous descendions les
