Background Thomas Day was a bachelor who had inherited his fortune from his father when he was an infant. Described as having a face pockmarked from
smallpox, a brooding personality, and a short temper, Day attended
Corpus Christi College, Oxford, to study philosophy. It was there that he decided to dedicate his life to becoming a virtuous man, shunning luxury and focusing on
altruism. Around the same time he developed a list of requirements for his future wife, that she should be subservient and pure but also able to discuss philosophy and live without frivolities. These high standards, combined with his generally unlikeable personality, meant that his advances were rejected by several women while he was at university. Day was introduced to the work of
Jean-Jacques Rousseau by his friend
Richard Lovell Edgeworth; the pair shared a particular affinity for Rousseau's work on education in the book
Emile, or On Education. On leaving Oxford, Edgeworth and Day attempted to teach Edgeworth's first son, Dick, in the style of
Emile, a
learning-by-doing approach. Accompanying Edgeworth to Ireland as Dick's tutor, Day fell in love and was spurned first by Edgeworth's sister, and then by at least three other women in quick succession. Day came to the conclusion that he would not be able to find a wife who would meet his high standards and largely blamed women's education for this. Inspired by the character of Sophie in Rousseau's
Emile, he resolved to "create" his ideal wife by raising her from adolescence, using the techniques laid out in the book. Day was approaching financial independence, when he would have full access to the money left to him, and conspired with his barrister friend,
John Bicknell, to find two girls who could be taken into his care to be groomed as a perfect wife.
Choosing the girls Just after Day's 21st birthday in June 1769, he and John Bicknell travelled to the Shrewsbury Orphan Hospital to choose the first girl for his experiment. Sidney was 12 years old at the time, described as "a clear auburn brunette, with darker eyes more glowing bloom and chestnut tresses". She was slender, and had long eyelashes and a pleasant voice. Day was struggling to choose a girl for the experiment, and Bicknell quickly picked her out. The pair did not tell the orphanage secretary, Samuel Magee, about the planned experiment. Instead they told him that she was to be indentured as a servant at Edgeworth's country house in
Berkshire, waiving the £4 () fee they would have received for the apprenticeship. In line with the orphanage's requirements that responsibility be held by a married man, Edgeworth would be legally accountable for Sidney, despite him not being present nor even aware of the arrangement. The apprenticeship was approved by the governors of the orphanage on 30 June 1769; Day and Bicknell collected Sidney on 17 August. She was brought to lodgings in London, where she met Edgeworth for the first time. Day changed her name to Sabrina Sidney: Sabrina, the Latin name for the
River Severn, which her orphanage overlooked; and Sidney after
Algernon Sidney, one of Day's heroes. Day became a benefactor, and subsequently governor, of the Foundling Hospital, and on 20 September 1769 he chose another girl for his experiment, renaming her Lucretia after the
Roman matron. Day had Bicknell draw up a contract to define the terms of the girls' indenture. Within one year, he would choose which girl he intended to marry, and the other would be given as an apprentice to a woman in a trade, along with a fee of £100 (). He would give a further £400 () upon the girl's marriage or if she were to start her own business. He would marry his intended bride or, if he decided not to, would gift her the sum of £500 (). Bicknell acted as guarantor for the contract.
Education in France ''. Day wished for the girls to be isolated from external influences while he educated them so, at the beginning of November 1769, he decided to move them to France. It is also possible that he did this to protect himself from the legal ramifications of his experiment, as well as societal gossip. The trio travelled over 600 miles to
Avignon, renting a house in
le quartier des fusteries. The girls could speak no French and Day employed no English-speaking servants, to be sure that he would be the only person to influence them. Day focussed on the girls' education, in the style of
Emile. He expanded on the teaching they had received from the Foundling Hospital in reading and basic arithmetic, and also taught them how to write. He believed that the girls should be able to manage the house, so they were charged with cooking and cleaning as well as other housework. Finally, he wanted to be able to debate complex concepts with them, so he taught them rudimentary theories in physics and geography, tasking them with observing the changing of the seasons, and recording details of sunrises and sunsets. He also imparted to them Rousseau's philosophical contempt for luxury. During his stay in France, Day regularly corresponded with Edgeworth. He said that both girls were passionate about their studies, Sidney more so. Day also related anecdotes, one concerning a trip on the
Rhone where the boat overturned and he rescued both girls single-handedly as neither could swim. He described an incident in which he challenged a French Army officer to a
duel, even producing a set of dueling pistols, simply as a manner of engaging or encouraging conversation with his young students; the officer apologised and explained he did not mean any offence, calming the situation. Accounts by 19th-century historians suggest that Day grew impatient with the girls when they became bored with their lessons and began to squabble, and that he also spent significant time nursing them through a bout of smallpox. These accounts may have been exaggerated as both girls had been
inoculated against smallpox, and their time at the Foundling Hospital would have discouraged such behaviour.
Return to England While in France, Day struggled over which girl to choose to take forward with the experiment. Both were beautiful; Lucretia was more cheerful, Sidney more reserved and studious. The trio returned to England in spring 1770, by which time Day had finally decided that he would carry on with Sidney's training. Edgeworth explained that each of Day's projects with Sabrina had been successful, but he had come to the conclusion that Lucretia was "invincibly stupid". Day apprenticed Lucretia to a
milliner in
Ludgate Hill, and took Sidney to Stowe House in
Lichfield, where her training could continue. The household would have had no more than a couple of servants, leaving Sidney to maintain the four floors of the house. Her tutoring continued at the same time, with one-on-one lessons from Day on a variety of subjects. Day extended his tutoring to fortify Sidney against hardship, again based upon his interpretation of Rousseau's
Emile. The book explains the concept of "negative education", protecting a person from vices rather than teaching them virtues. Day interpreted this to mean that submitting Sidney to tests of endurance would help to create a woman with hardened nerves. One example given by Rousseau was helping Emile become accustomed to explosions such as fireworks by firing pistols with small amounts of powder near him, gradually increasing the amount of powder. Day, on the other hand, fired a pistol loaded with powder directly at Sidney's petticoat, not telling her that there was no shot in it. In an attempt to increase her resistance to pain he would drop hot
sealing wax on her back and arms or stick pins in her, commanding her not to cry out. He would test her ability to keep secrets by telling her that his life was in danger and she should tell no one. To increase her resistance to the cold, Day instructed Sidney to wade into
Stowe Pool until the water reached her neck, then lie in the nearby meadow until her clothes and hair had dried in the sun. Finally, to test her resistance to luxury, he gave her a big box of handmade silk clothes and had her throw them on a fire. Day had limited success with these techniques. Sidney became able to endure hot wax dripped on her arm without flinching, but she did tell others of his secret techniques, and could not help screaming whenever he fired his gun at her. During their time at Stowe House, Day introduced Sidney to members of the local intellectual circle, including the priest at
Lichfield Cathedral,
Thomas Seward. Seward and his wife hoped that Day might be a suitor for their daughter,
Anna, and Anna's writings of the time show her interest in Day. Anna was also enchanted by Sidney, who became the link between Day and the Seward family. Anna took a keen interest in Sidney's story, as her father had taken in
Honora Sneyd when Sneyd's mother had died. == Moving away from Day ==
