Now, any one who holds a layer of tinfoil against the fluoro- scope will see that it is penetrated by X-rays about as easily as thin board. The rays get through it with scarcely a shadow; therefore the X rays reached the part of his finger which was covered by tinfoil. Under the tinfoil strip there was no action upon the skin, but on the rest of the skin a little dermatitis manifested itself on the ninth day. If this experiment does not demonstrate the fact that X rays do not burn, it is difficult to see how any fact can be conclusively demonstrated. The cause of the occasional dermatitis is some other influence than the X ray, and it is so easily avoided that it is not a matter of importance.
