When taken in the evening it was followed by great restlessness, loss...

Página 3 - ... very carefully freed from the connective tissue surrounding them. If the animal be strong, and have thoroughly recovered from the chloroform and from the operation, irritation of the peripheral stump of the anterior root causes not only contractions in the muscles supplied by the nerve, but also movements in other parts of the body indicative of pain or sensations.
Página 143 - ... a foolish opinion, advanced of late years, that we ought to spell exactly as we speak; which, beside the obvious inconvenience of utterly destroying our etymology, would be a thing we should never see an end of. Not only the several towns and counties of England have a different way of pronouncing, but even here in London they clip their words after one manner about the court, another in the city, and a third in the suburbs; and in a few years, it is probable, will all differ from themselves,...
Página 98 - When milk contained in wire-corked bottles, is heated to the boiling point in a water bath, the oxygen of the included small portion of air under the cork seems to be carbonated, and the milk will afterwards keep fresh, it is said, for a year or two , as green gooseberries and peas do by the same treatment.— Butter and cheese are made of milk, by processes not accessary to describe in thia place.
Página 84 - The potters as a class, both men and women, represent a degenerated population, both physically and morally. They are, as a rule, stunted in growth, ill-shaped, and frequently ill-formed in the chest; they become prematurely old, and are certainly short-lived; they are phlegmatic and bloodless, and exhibit their debility of constitution by obstinate attacks of dyspepsia, and disorders of the liver and kidneys, and by rheumatism. But of all diseases they are especially prone to chest-disease, to pneumonia,...
