But I had been made very angry. A large party had been invited I neither liked nor approved of, and invited for the sole purpose of vexing me. Our house being in the centre of the garden, walled around, with iron gates, I put on my hat, walked down to the porter's lodge, and gave him orders, on his peril, not to...
Strona 148 - This appears by the way whereby heat is produced ; for we see that the rubbing of a brass nail upon a board will make it very hot ; and the axle-trees of carts and coaches are often hot, and sometimes to a degree that it sets them on fire, by the rubbing of the nave of the wheel upon it.
Strona 140 - That Mr. Humphry Davy be engaged in the service of the Royal Institution, in the capacity of Assistant Lecturer in Chemistry, Director of the Chemical Laboratory, and Assistant Editor of the Journals of the Institution ; and that he be allowed to occupy a room in the house, and be furnished with coals and candles, and that he be paid a salary of 100 guineas per annum.
