to show their combs in a few days. 

 Though small, you can easily observe 

 those which are close and well shaped 

 from those which will be upright 

 and straggling. Select the best, pot 

 them and continue repotting, and en- 

 courage with heat and manure water, 

 and the strength of your culture going 

 chiefly into the combs, these will be 

 large, while your plants will be small. 

 Where extremely dwarf plants are 

 wanted, cut off young plants a little be- 

 low the comb ; insert the part with the 

 comb into a small pot in sandy soil, in 

 strong heat and a hand-glass over. Soil, 

 sandy loam and very rotten dung, but 

 sweet. Temperature when growing 60 

 to 8-5 by day ; 60 at night 



CE'LSIA. (Named after Professor Cel- 

 sius, of Upsal. Nat. ord., Figtvorts 

 [Scrophulariaceae]. Linn., \-Didynamia, 

 2-angiospermia). Chiefly from seeds, or 

 raised in a slight hotbed in March or 

 April, and flowered in the greenhouse 

 during the summer, or in favourable 

 positions out of doors. The biennials 

 require the protection of the cold pit 

 during winter ; light sandy open soil.

CE'LTIS. Nettle Tree. (The name of 

 a tree mentioned by Pliny. Nat. ord., 

 Elmworts [Ulmacese]. Linn., 23-Poly- 

 gamia, 1-moncecia). Seeds, sown as soon 

 as ripe ; layers also and cuttings of ripe 

 shoots in autumn; common good soil. 

 The East and West India species require 

 protection, but there seems little to re- 

 commend in them over the European 

 and North American species which are 

 hardy. The wood of australis is ex- 

 tremely pliant.

CENTAURE'A. Centaury. (The classical 

 name of a plant, fabled by Ovid to have 

 cured a wound in the foot of Chiron 

 Chiron being one of the centaurs, or war- 

 horse breakers, of Thessaly. Nat. ord., 

 Composites [Asteracese]. Linn., l^-St/nye- 

 iiesia, 3-frustraned), The Centaury s are 

 so numerous that more than twenty ge- 

 neric names have been applied to the 

 species. C. cyanea and dtpressa, or corn 

 flowers, are much used in bouquets. 

 Seeds of most of them in the open border 

 in the end of March. The tenderer ones 

 may be raised on a hotbed ; transplanted 

 to another : a few might be preserved 

 in a cold pit if it was deemed desirable. 

 Common soil.
