THE OX AND THE DAIRY. 23 



tremely fond. To these may be added, the small water-wort 

 (elatine hydropiper), box-leaved andromeda (a. calcyculata), 

 biting stone-crop (sedum acre), snapdragon (antirrhinum lina- 

 ria), stinking chamomile (anthemis cotula), black-berried 

 bryony (bryonia alba), marsh lousewort (pedicularis palus- 

 tris), wood lousewort (p. sylvatica), hemp agrimony (eupa- 

 torium cannabinum), annual mercury (mercurialis annua), 

 deleterious to all domestic animals ; corn horsetail (equisetum 

 arvense), marsh horsetail (e. palustre), and the male polypody 

 (polypodyum filix mas). 



Some plants are eaten solely by the hog ; but it is only 

 their roots, in general, that are sought after Among these 

 are the common cyclamen (cyclamen Europseum), common 

 asarabacca (asarum Europ8eum),the white and the yellow water- 

 lily (nymphsea alba, and lutea), towards which the horse ex- 

 hibits a marked aversion ; the water-soldier (stratiotes aloides), 

 sea-wrack-grass (fostera marina), and maiden-hair (asplenium 

 trichomanes). The hog also greedily searches the ground for 

 earth or pig-nuts, the roots of the two species of umbelliferous 

 plants, buriium bulbocastanum, and b. flexuosum. 



A few plants are relished by all domestic herbivorous ani- 

 mals, and are much sought after ; among these are the com- 

 mon millet-grass (millium effusum), meadow soft-grass (holcus 

 lanatus), annual meadow-grass (poa annua), oats, barley and 

 wheat, the carrot and parsnip, the great round-leaved willow 

 (salix caprea), the Norwegian cinquefoil (potentilla Norvegica), 

 the creeping trefoil or Dutch clover, and other species of 

 clover, lucern, sainfoin, &c. But many of these plants must 

 be in different states in order to be equally liked by every 

 domestic species. It is observed of the cotton grasses (erio- 

 pharum) that they are hurtful to cattle from their hairs, which 

 are apt to serve as a nucleus to those concretions of extraneous 

 matters sometimes found in the stomach. The utility of root- 

 ing up as much as possible all noxious plants from pasture 

 grounds, and the ditches around them, is palpable, and it 

 would be well if the farmer attended to this point more than 

 is usually the case. 



It is riot very easy, unless the fact be ascertained from cir- 

 cumstances, to determine positively that a suffering beast is 

 labouring under the effects of poisonous plants taken into the 

 stomach. The general symptoms are stupor, and great swell- 

 ing ; a refusal of food, a grinding of the teeth, and a rolling 

 about as if from extreme agony or colic. The first thing to
