A new traveller in Africa has come across a part of the country where ants are found as large as roaches, and prove themselves masters of man and beast. They make every known animal disappear, infesting the napes of cattle and killing them outright. Dr. McCook, we hope, will not endeavor to introduce them for examination.

Sir John Lubbuck, who is a minute observer of nature's doings, says : "The flower of the little Linaria of our walls pushes out into the light and sunshine, but as sure as it is fertilized it turns round and endeavors to find some hole or cranny in which it may remain safely until the seed is ripe." See his curious articles republished in the Popular Science Monthly.
