If a hen and a half lays an egg and a half

If a hen and a half lays an egg and a half in a day and a half, how many eggs will five hens lay in 6 days?

5 hens would lay 5 eggs in a day and a half.
In 6 days, there are 4 day-and-a-half
5 x 4 = 20
(each hen lays 2/3 egg per day)

The Chemical History of a Candle

I saw the other day an experiment which pleased me much, as I thought it would serve our purpose here. (I ought to have held my tongue for four or five minutes before beginning this experiment, because it depends upon my lungs for success.) By the proper application of air, I expect to be able to drive this egg out of one cup into the other by the force of my breath; but if I fail it is in a good cause, and I do not promise success, because I have been talking more than I ought to do to make the experiment succeed.

Cleaning Leather on Furniture

Beat up the whites of three eggs carefully and use a piece of flannel to rub it well into the leather which will become clean and lustrous. For black leathers, some lampblack may be added and the mixture applied in the same way.
