THE MARCH OF SCIENCE.

Heredity especially on the six side, took an important place in the discußsions at the British Association's recent meetings at Birmingham. One very .•Strange point was brought out by Major Hurst, the owner of tke hereditary farm. It is now .more or less established that certain qualities are anly paseed on b*- one sex. This is the caee in a certain form of short eight in men, but the ease anuounced concerned poultry. In regard to the quality of high egg yield hens only inherit through their sire, never through their dam. and there is some reason to believe that this is so in respect of the milk-yielding qualities of cows. The importance of such a fact if established is obvious. SQGQ-year-old Incubator. Poultry provided one of the surprises of the agricultural section. Mr W. H. Cadman has penetrated an immensely old secret in poultry breeding. The ■Egyptians .turned out 120,000,00(3 poultry a year from native incubators, wh'ch'in some form have been used for 5000 years. The'secret has been religiously guarded from 3000 8.C., but is for the first time now laid bare, and is sufficiently astonishing. They appear to be vastly better than the most modern .■productions. Each incubating oven contains 7000 egg?. lb is heated by very .•■mall fuel suppj : es of chopped ctraw and dung, and for the last 10 days the heat is whollv fiUDijlied by the energy of the developing chicken in the egg. The hirer; who is an examiner m agricultural chemist?- thinks that the introduction of this historic- Egyptian- incubator to England would reform th« industry.
