all diseases. Linn. 21, Or. 10, Nat. Or. Pi- 

 naceai. In Britain the species of Arbor Vitce 

 ,oan only be considered as ornamental, low 

 .shrubs or trees, well deserving of being culti- 

 vated, especially T. pindula; which, on ac- 

 count of its very graceful, long, slender, pen- 

 dulous shoots, ought to be in every collection. 

 The American and European kinds succeed 

 well in any soil or situation, but prefer low, 

 sheltered, and swampy places. The more 

 tender species, natives of China, require, 

 when young, the protection of the greenhouse. 

 They are all readily increased by seeds, either 

 imported from the places of their natural 

 growth, or gathered from the trees in this 

 country ; some of the rarer kinds, as T. pin- 

 dula, are propagated by cuttings. Synonymes :

 Tfftf MBRA, Linn. Thymbra is the Greek name 

 of a sweet-scented herb. Linn. 14, Or. 1, 

 Nat. Or. Lamiacece. This genus is well adapted 

 for rock-work, or growing in pots among alpine 

 plants. A gravelly soil suits it best, and it is 

 readily increased by young cuttings or seeds.

Thyme. See Thymus. 



ThymeleacEjE, or Daphnads. The Mezereon 

 (Ddphne Mez&reum) and Spurge laurel (Ddphne 

 Lauredla) are two types of the habits of the 

 order ; the bark of all the species is so caustic, 

 that, if chewed, it causes excessive pain. 

 They all deserve cultivation. 



Thymus, Linn. From thumos, courage, strength, 

 the smell of thyme being reviving ; or from 

 thuo, to perfume, being formerly used for in- 

 cense in the temples. Idnn. 14, Or. 1, Nat. 

 Or. Lamiaeeoe. Well-known under shrubs or 

 herbs, preferring an exposed situation, and iL 

 dry, light, sandy soil. They are of very easy 

 culture, and may be increased with facility 

 either by divisions, slips, cuttings, or by seeds 

 sown in March or April. Some of the rarer 

 species may be grown in pots among alpine 

 plants, and protected in winter. The different 

 purposes to which Thyme is applied are so 

 well known, as not to require any notice here.
