400 PHYSIOLOGY AT THE FAEM. 



3. C orymbiferce, Chamomile order. Achillcea millefolium, 

 common milfoil or yarrow, is a fibrous-rooted perennial. It 

 flowers in June and July, and at times in the later months. 

 It grows in sandy downs, by waysides, and in waste places. 

 It is an astringent, and is greedily sought after by sheep. It 

 is recommended to be sown for warrens or light sandy downs 

 to the extent of J Ib. per imperial acre. A bushel of the seed 

 averages 29J Ib., and the number of seeds in an ounce reaches 

 200,000.

 some weed, yet sheep are evidently fond of it ; and he goes on

 other plants sheep may be led to seek after them not as food 

 but as medicine. A. moschata or Ptarmica moschata, a native 

 of the southern parts of Europe, the genipi of the Swiss, is a 

 grateful food to cattle. In Savoy it is called Genipi batard, 

 the true name, genipi, according to the Savoyards, being appli- 

 cable to the Artemisia rupestris, and even to the A. spicata 

 and A. anethifolia, all of which are in esteem as medicines. 

 The Achillcea moschata or Ptarmica moschata is the basis of 

 the aromatic liquor called "Esprit d'lva." 



Artemisia absinthium, wormwood, a native plant hardly 

 nutritive. A. vulgaris, common mug- wort, is used in some 

 parts of Sweden instead of hops in malt-liquor. This last plant 

 is readily eaten by cattle and sheep, yet its nutritive property
