Later he paraphrases a celebrated classic to illustrate the sequence of disease transmission: "This is the germ of the bubonic plague...
...causative microbe of the disease is still unknown. A number have been cultivated from the virus, but their identity with the germ is doubtful. It may be destroyed by heating to 60° Centigrade, and has been demonstrated by German investigators to be capable of passing through the pores of a porcelain filter. It probably belongs therefore to the class of ultramicroscopic organisms called filterable viri. One attack of the disease usually confers immunity on the cattle for several years, and animals have been imunized artificially by dosages of the sera of infected animals...
...Senate there are two names which stand out preëminently, but in somewhat different ways. One of these is La Follette. The other is Borah. The oil investigation is something that Mr. La Follette started. Of late Mr. Borah has started nothing of equal prominence. The germ of an important development may, however, lie in a resolution which Mr. Borah introduced last week...
...TIME, May 12, June 18, Dec. 10), who believes he has experimental proof of the inheritance of acquired characteristics. Dr. Kammerer, though now in this country, was not invited to Cincinnati. Most American biologists, while recognizing that animals or plants may have experiences (poisons, for instance), which affect the germ plasm in such a way as to cause changes in the progeny, say that Dr. Kammerer's methods have not met sufficiently critical tests to justify his conclusions. Replying to MacDougal from New York, Kammerer questioned the open-mindedness of American biologists...
...Robert T. Hance, of the University of Pennsylvania, told of an improved technique for studying the chromosomes of chicks. All of the hereditary characteristics of animals are transmitted to their offspring through tiny bodies called chromosomes in the two microscopic germ-cells contributed, one by each parent. Research on chromosomes has become very exact; they can be counted, and their various divisions, pairings and combinations recorded...
