 in much he falls far behind us."" 



When I left England, my intention was, after getting through 

 the private business that called me to Paris, to set off direct to 

 Switzerland, and there spend the summer. When, however, at 

 Paris, I received so many requests from my valued friend Mr 

 Bentham to pay him a few days' visit at Montpellier, that I was 

 induced to accede to his wishes until the season was sufficiently 

 advanced for a Swiss tour. You know that natural history is 

 one of the branches to which I have long paid attention ; in- 

 deed, I have to thank yourself for that taste, having acquired 

 it when attending your classes eight or ten years ago. One 

 branch of natural history leads to another, and if I have now 

 given up mineralogy, and attended chiefly to botany, it is not 

 that I disHke the former, but find it rather a too weighty and 

 bulky study, while plants are much more portable. The kind- 

 ness of Baron B. Delessert, in throwing open to me his rich her- 

 barium, gave me an opportunity of studying attentively the col- 

 lection of Palisot de Beauvois, now in his possession, and enabled 

 me to make out what many of his hitherto doubtful species of 

 mosses are. A notice of these may be of little interest to some, 

 while to others it may be useful. I shall, therefore, here mark 

 a few of the most important. 



Bartramia subintegrifolia is Bartramia gracilis. 



Bryum gymnostomoides is not in Beauvois' herbarium, and maybe there- 

 fore rejected as a doubtful species. It is pos- 

 sibly Weissia Templetoni. 



Cecalyphum cylindraceum....is, I think, a variety of his Cecalyphum perichcBtia- 

 le: both belong to Dicranum, and approach close- 

 ly to Z>. calycinum. 



longirostratum. .is Dicranum Schraderi in a young state. 



tortile is Dicranum flagellare. 



Dicranum dichotomum is Thysanomitrion nivale. 



phascoideum is Grimmia pagiopodon. 



striatum. is a Trichostomum. 



Fissidens dubius. , is Dicranum adiantioides var. 



Fontinalis squamosa The fruit is in a bad state, so that I am doubt- 

 ful whether this belongs to F. squamosa, or 

 should be imited with F. disticha Sprengel, 

 and form a distinct species.
