Strana 2 - Farewell the tranquil mind ! Farewell content ! Farewell the plumed troop, and the big wars, That make ambition virtue ! O, farewell ! Farewell the neighing steed, and the shrill trump, The spirit-stirring drum, the ear-piercing fife, The royal banner ; and all quality. Pride, pomp, and circumstance of glorious war ! And O, you mortal engines, whose rude throats The immortal Jove's dread clamours counterfeit, Farewell ! Othello's occupation's gone ! lago.
Strana 260 - Exchanges were effected with other medical libraries not only in this country but in all parts of the world.
Strana 91 - I have lived," said Dr. Adam Clarke, " long enough to know that the great secret of human happiness is this : never suffer your energies to stagnate. The old adage of " too many irons in the fire,
Strana 263 - There is no profession which can be compared in importance with that of agriculture, for to it belongs the production of food for man and animals ; on it depends the welfare and development of the whole human species, the riches of states, and all commerce. There is no other profession in which the application of correct principles is productive of more beneficial effects, or is of greater and more decided influence.
Strana 258 - When riding, it is a common thing to meet a large flock of sheep guarded by one or two dogs, at the distance of some miles from any house or man. I often wondered how so firm a friendship had been established. The method of education consists in separating the puppy, while very young, from the bitch, and in accustoming it to its future companions. An ewe is held three or four times a day for the little thing to suck, and a nest of wool is made for it in the sheep-pen; at no time is it allowed to...
Strana 209 - And could not heave her head, The tuneful voice was heard from high, Arise, ye more than dead. Then cold and hot and moist and dry In order to their stations leap, And Music's power obey. From harmony, from heavenly harmony This universal frame began : From harmony to harmony Through all the compass of the notes it ran, The diapason ending full in Man.
Strana 296 - ... the alkaline matters used may be changed, and the same rendered less soluble, so that the otherwise soluble alkaline parts of the manure may not be washed away from the other ingredients by the rain falling on the land, and thus separating the same therefrom. And it is the combining carbonate of soda or carbonate of potash, or both with carbonate of lime, and also the combining carbonate of potash and soda with phosphate of lime, in such manner as to diminish the solubility of the alkaline salts...
Strana 251 - Philadelphia Society for Promoting Agriculture," p. 196, where yon will see a paper of mine on the subject, which I think will leave no room to doubt as to the cause of the disease. It is a curious fact that the ergot of rye, if ground into meal with sound rye, when made into bread and eaten produces mortification of the lower extremities in France.
Strana 260 - All the horses bred here, both tame and wild, are rather small-sized, though generally in good condition; and they have lost so much strength, that they are unfit to be used in taking wild cattle with the lazo: in consequence, it is necessary to go to the great expense of importing fresh horses from the Plata. At some future period the southern hemisphere probably will have its breed of Falkland ponies, as the northern has its Shetland breed.
Strana 233 - Yesterday the sullen year Saw the snowy whirlwind fly; Mute was the music of the air, The herd stood drooping by; Their raptures now that wildly flow No yesterday nor morrow know; 'Tis Man alone that joy descries With forward and reverted eyes.
