Dr. Vaughan's Experiments

The following interesting infornuition is gleaned from the report sent out by the state board of health at its last meeting: "For a few years past Prof. Vaughan, of the state board of health, has been engaged in some very important experiments in the state laboratory of hygiëne at the Unlverslty. These experiments relate to subjeots of very great importance to the public welfare. One purpose is to accomplish the end which at one time it was thought had been reached by Dr. Koch, namely, the preparation of a substance which can be introduced into the body and which shall antagonize gernis of il soase such as those of consumption. Prof. Vaughan is' now able to prepare a substance which there is reason to believe may be similar to the one normally used by the body in battling wlth the germs of disease. Hls experiments are not yet conclusive as to the usefulness of this substance for the cure of' disease, but they tend to prove that by its use immunity to the contraction of germ disease is enhanced. The substance consists of the nuclei of cells, and since it is probable that the spleen is the organ in the body which takes the most active part in battling with germs of disease, he has given special attention to the preparation of 'nuclein' made from the cells of the spljen. "Prof. Vaughan has presented this subject before the medical societies in this country, and he now goes to the international congress of hygiëne which meets in September, this year, in BudaPesth, Hungary, wotve he expects (..■ meet the scientists engaged in this and other lines of scientific work, who . 11 be there from every civilized country. From the discussions which will there take place, he expects to gain much knowledge which will enable him to continue and extend his exceedinly important work. He goes as a delégate from the Michigan state board of health, and the board expects Prof. Vaughan to contrlbute, for the welfare of humanity, fully as much information as he will receive. This is not Prof. Vanghan's first trip across the ocean. His first one was some years ago for the purpose of atudying bacterio!' gy in the laboratory of Prof. Koch. Three years ago he attended the international congress of hygiëne, which then met In London, England. His present trip is regarded as of much greater importance in eonnectkm with public health work."
