name, Hottonia, in honour of the well-known 

 Dutch botanist, Hotton. 



The Water Crowfoot, or White Water Butter- 

 cup, should always form one of the plant-collec- 

 tion in an Aquarium, on account of its peculiar and 

 interesting growth. The leaves of this plant, while 

 they grow beneath the water, are so deeply " cut " 

 or branched, as to appear almost fibrous in their 

 character, like those of the class of plants which 

 never appear above the surface. But the fibres of 

 those leaves which are developed above the water 

 become connected by the same kind of tissue as 

 that which usually connects the veins of ordinary 

 aerial leaves. In this new condition the upper 

 foliage assumes quite a different character, and the 

 plant has thus the appearance of being furnished 

 with leaves of two remarkably distinct kinds. 



The common Brooklime, though rather coarse 

 in its growth, puts forth its racemes of pretty blue 

 flowers very abundantly ; and the esculent Water- 

 cress is also worthy of cultivation in the Aquarium, 

 especially when treated in the following manner : A 

 few seeds should be procured, which can be purchased 

 of any of the leading seedsmen, and sown in the 

 bottom of the tank, where they will soon produce a 

 very pretty green crop, over the undulations of the
