Origins of Life
If earth's history were compressed into one calendar year, earth forms, cools and develops an atmosphere during January. Late January into February sees global volcanic activity as oceans fill the great basins. Life begins somewhere in March. All of human history occurs in the last 7 minutes of December 31, and Columbus "discovers" America only 3 seconds before the clock strikes midnight (midnight = today).
Recipe for bees:
Kill a young bull, and bury it in an upright position so that its horns protrude from the ground. After a month, a swarm of bees will fly out of the corpse.
Jan Baptista van Helmont’s recipe for mice:
Place a dirty shirt or some rags in an open pot or barrel containing a few grains of wheat or some wheat bran, and in 21 days, mice will appear. There will be adult males and females present, and they will be capable of mating and reproducing more mice.
