A whimsical interpretation of the human body as a house, with Jack's study at the top, and various windows and doors for sensory input to enter through. From a series of articles in The Book of Knowledge, 1910s. The articles may be an adaptation of this book, although I was unable to find any direct one-for-one quotes in The Book of Knowledge.
