Página 495 - Mere carelessness this; but such carelessness as is of constant recurrence. P. 204. — " Bodies of equal section very often possess different relative strengths ; the formula Pi =-5. ÍA* 6 shows that the strength increases in the breadth as the square of the depth, and inversely as the length of the beam. The depth has consequently a greater influence upon the tenacity than the breadth ; a beam of double the breadth bears twice as much : ie, as much as two single Seams : on the other hand a beam...

After the lapse, however, of about three days, the same gentleman discovered their...
Página 19 - Europe, and with heavy orders for agricultural produce, the farmers in the interior of the stale of New York, informed of the state of things by the magnetic telegraph, were thronging the streets of Albany with innumerable team-loads of grain almost as quickly after the arrival of the steamer at Boston as the news of that arrival could ordinarily have reached them.
Página 130 - The honour of belonging to the Royal Society is much sought after by medical men, as contributing to the success of their professional efforts, and two consequences result from it.

On the other hand, medicine is intimately connected with...
