it is back in our collection in storage along with the letter, the original letter from william massey, and the hopes that he would protect his own family against smallpox. the ways in which humans are able to stand out and eradicate this deadly, deadly disease. i am happy to take your questions, please add your questions into either facebook or youtube, and let me turn to -- your questions. it was my understanding that viruses were not known specifically in the 18th century, so use of that word is modern usage. yeah, that is correct. as i mentioned, people from observing news as you can pass diseases like the v bonnet plague and smallpox, they knew that they got transmitted, but they did not understand the medical science behind it. it was not until later in the 19th century with the development of germ theory, and development of the medical equipment that could look at these pathogens on an anatomical level that they -- did they really understand how virus works, but i was using the modern understanding of virus just for clarity sake here. thank you for the question. another question
