The Cow has given its name to a whole series of plants: its Berry is _Vaccinium Vitis idæa_, its Cress, _Lepidium campestre_, its Parsley or Weed, _Chærophyllum sylvestre_, its Parsnip, _Heracleum Sphondylium_, its Wheat, _Melampyrum_. The Quaking Grass, _Briza media_, is known as Cow Quake, from an idea that cattle are fond of it; and the Water Hemlock (_Cicuta virosa_) has the opprobrious epithet of Cow Bane applied to it, from its supposed baneful effect upon oxen. The _Primula veris_ is the Cowslip. In Norway is to be found the herb Ossifrage--a kind of Reed which is said to have the remarkable power of softening the bones of animals; so much so, that if oxen eat it, their bones become so soft that not only are the poor beasts rendered incapable of walking, but they can even be rolled into any shape. They are not said to die however. Fortunately they can be cured, if the bones are exhibited to them of another animal killed by the eating of this plant. It is most wonderful, however, that the inhabitants make a medicine for cementing bones from this very herb. There are several plants dedicated to man’s faithful friend. Dog’s Bane (_Apocynum_) is a very curious plant: its bell-shaped flowers entangle flies who visit the flower for its honey-juice, so that in August, when full blown, the corolla is full of their dead bodies. Although harmless to some persons, yet it is noxious to others, poisoning and creating swellings and inflammations on certain people who have only trod on it. Gerarde describes it as a deadly and dangerous plant, especially to four-footed beasts; “for, as Dioscorides writes, the leaves hereof, mixed with bread, and given, kill dogs, wolves, foxes, and leopards.” Dog’s Chamomile (_Matricaria Chamomila_) is a spurious or wild kind of Chamomile. Dog Grass (_Triticum caninum_) is so called because Dogs take it medicinally as an aperient. Dog’s Mercury (or Dog’s Cole) is a poisonous kind, so named to distinguish it from English Mercury. Dog’s Nettle is _Galeopsis Tetrahit_. Dog’s Orach (_Chenopodium Vulvaria_), is a stinking kind. Dog’s Parsley (_Æthusa Cynapium_), a deleterious weed, also called Fool’s Parsley and Lesser Hemlock. Dog Rose (_Rosa canina_) is the common wilding or Canker Rose; the ancients supposed the root to cure the bite of a mad Dog, it having been recommended by an oracle for that purpose; hence the Romans called it _Canina_; and Pliny relates that a soldier who had been bitten by a mad Dog, was healed with the root of this shrub, which had been indicated to his mother in a dream. Dog’s Tail Grass (_Cynosurus cristatus_) derives its name from its spike being fringed on one side only. Dog Violet (_Viola canina_) is so-called contemptuously because scentless. Dog’s Tongue, or Hound’s Tongue (_Cynoglossum officinale_) derived its name from the softness of its leaf, and was reputed to have the magical property of preventing the barking of Dogs if laid under a person’s feet.
