...called in question. The influence of natural selection, his favorite theory, is not agreed upon; his emphasis on Lamarck's doctrine of the inheritance of characters acquired by environmental factors such as use and disuse is now largely discredited; of the phenomena of variation and the mechanism of the germ-cell he knew little. But whether or not species originate as Darwin thought they did, this "grandest generalization of the 19th century"?the continuous relation of all species to pre-existent life ?is an incontrovertible fact. Many laymen do not understand the scientific spirit which calls for constant...

Dr. Tomarkin's cure merits favorable consideration, at least, from the fact that it is vouched for by Professor Ettore Marchiafava, one of the most respected of Italian medical scientists, famous for his work on plasmodium, the germ of malaria...
Common colds are infectious and are probably due to an ultramicroscopic germ. These are the findings of Dr. Peter K. Olitsky and Dr. J. E. McCartney, of the Rockefeller Institute for Medical Research, after four years of experiments on human volunteers. Filtered washings from the noses of cold sufferers were injected into healthy persons, who promptly developed colds, which were in turn transmissable. The causative germ could not be seen, although cultures were grown from the secretions of 40 patients. Either the germ is so small that it cannot be seen through the most powerful magnification (about 1,500 times...
