How do i get a primary resource? URGENT!!?

I am writing a history paper. The topic given is innovation, we have to pick one. I chose x-rays, and it is too late to change my topic. We must have an annotated bibliography with both primary and secondary resources. It is due on wednesday and i still dont have any primary resources. By definition a primary resource is something from the time that whatever it is your writing about is from. X-rays were invented in 1895. I need a doent from 1895 or possibly even a year later. I have searched and searched but have not succeeded. I should have at least 5 to turn the paper in and expect to not fail. If you know of/can find any type of doent from that time on line or in any book please PLEASE please post a link as an answer to this question. thankyou. :)
