Emma and Christy discover Margaret Watts Hughes's beautiful 'voice figures', a series of images made through the direct action of her voice between 1885 and 1904. In this episode, we discuss the earliest sound recordings, scientific 'instruments' (it's a pun), cat pianos, severed ears, occult science, seaweed scrapbooks, women in STEM, logos and the word of God, visualising the invisible, the Little Mermaid, clairvoyant research, 'thought forms' and the death agonies of pigeons, science and feeling, and why sonic media is always already haunted.
