346 REVIEW. [November, 



oommunicated to that flourishing association. One of these is 

 entitled " Seaweed as a Manure," an article that cannot be much 

 known practically in Upper Canada, and cannot be expected to 

 excite much interest ; potash or its refuse, if there be any, would 

 be more likely to rouse the attention of West Canadian farmers. 

 The writer relates its utility in fertilizing the sandy hills of the 

 east coast of Scotland. But the learned Professor must know 

 that its application there is easy, because these sandhills (sand 

 dunes, he calls them) are contiguous to the shore. It would be 

 expensive to convey a bulky material like seaweed a distance of 

 a thousand miles. Possibly the author intended that the phos- 

 phates and other manureal materials should be extracted before 

 its conveyance to the Upper Province. 



In the April number of this periodical there is a list of plants 

 collected in the counties of Argenteuil and Ottawa in 1858, by 

 W. S. M. D'Urban. This gentleman was five months in the 

 district, and probably observed most of the plants growing there. 

 His list is arranged systematically, and he prefixes an asterisk to 

 the introduced or naturalized species. 



The entire catalogue of phaenogamous and cryptogamous plants 

 observed by him during a residence of five months, consists of 

 362 species, viz. 276 of the former and 86 of the latter. A com- 

 parison of the species common to both Britain and America 

 (Upper Canada) may be interesting to those who study the dis- 

 tribution and relations of plants, or to phytogeographers, as 

 they delight to call themselves. 



Among the 276 phsenogamous plants of Canada enumerated 

 in this list, there are 38 common to both Europe and America, 

 viz. Ranunculus Flammula, Caltha palustris, Actaa spicata, Car- 

 damine hirsuta, Drosera longifolia, Oxalis Acetosella, Spircea sa- 

 licifolia, Agrimonia Eupatoria, Fragaria vesca, Epilobium angus- 

 tifolium, (Enothera biennis, Circaa alpina, Ribes rubrum, Linncea 

 borealis, Viburnum Opulus, Erigeron canadensis, Vaccinium Oxy- 

 coccus, Andromeda polifolia, Pyrola rotundifolia, P. secunda, 

 Monotropa Hypopitys, Utricularia vulgaris, Veronica scutellata, 

 Prunella vulgaris, Scutellaria galericulata, Menyanthes trifoliata, 

 Polygonum aviculare, Myrica Gale, Acorus Calamus, Typha lati- 

 folia, Sparganium simplex, Juncus tenuis, J. bufonius, Eleocharis 

 palustris, Scirpus sylvaticus, Carex tenella, Agrostis vulgaris, Poa 

 pratensis, Milium effusum.
