Good morning, Whitewater.

A new month begins, with a mostly sunny day, a high of eighty-one, and a forty percent chance of afternoon showers. Sunrise is 5:46 AM and sunset 8:16 PM. The moon is a waxing crescent with twenty-seven percent of its visible disk illuminated.

On this month in 1774, Joseph Priestly discovers oxygen (with other scientists having a role in its discovery, also):

In August 1774 he isolated an “air” that appeared to be completely new, but he did not have an opportunity to pursue the matter because he was about to tour Europe with Shelburne. While in Paris, however, Priestley managed to replicate the experiment for others, including French chemist Antoine Lavoisier. After returning to Britain in January 1775, he continued his experiments and discovered “vitriolic acid air” (sulphur dioxide, SO₂).

In March he wrote to several people regarding the new “air” that he had discovered in August. One of these letters was read aloud to the Royal Society, and a paper outlining the discovery, titled “An Account of further Discoveries in Air”, was published in the Society’s journal Philosophical Transactions.^[99] Priestley called the new substance “dephlogisticated air”, which he made in the famous experiment by focusing the sun’s rays on a sample of mercuric oxide. He first tested it on mice, who surprised him by surviving quite a while entrapped with the air, and then on himself, writing that it was “five or six times better than common air for the purpose of respiration, inflammation, and, I believe, every other use of common atmospherical air”.^[100] He had discovered oxygen gas (O₂).

Priestley assembled his oxygen paper and several others into a second volume of Experiments and Observations on Air, published in 1776. He did not emphasise his discovery of “dephlogisticated air” (leaving it to Part III of the volume) but instead argued in the preface how important such discoveries were to rational religion. His paper narrated the discovery chronologically, relating the long delays between experiments and his initial puzzlements; thus, it is difficult to determine when exactly Priestley “discovered” oxygen.^[101] Such dating is significant as both Lavoisier and Swedish pharmacist Carl Wilhelm Scheele have strong claims to the discovery of oxygen as well, Scheele having been the first to isolate the gas (although he published after Priestley) and Lavoisier having been the first to describe it as purified “air itself entire without alteration” (that is, the first to explain oxygen without phlogiston theory).^[102]

In his paper “Observations on Respiration and the Use of the Blood”, Priestley was the first to suggest a connection between blood and air, although he did so using phlogiston theory. In typical Priestley fashion, he prefaced the paper with a history of the study of respiration. A year later, clearly influenced by Priestley, Lavoisier was also discussing respiration at the Académie des sciences. Lavoisier’s work began the long train of discovery that produced papers on oxygen respiration and culminated in the overthrow of phlogiston theory and the establishment of modern chemistry.^[103]

Good morning, Whitewater.

Our month ends with a mostly sunny day, a high of eighty, and just a thirty-percent chance of late afternoon thunderstorms.

On this day in 1777, the Marquis de Lafayette commits to America:

…a 19-year-old French aristocrat, Marie-Joseph Paul Roch Yves Gilbert du Motier, Marquis de Lafayette, accepts a commission as a major-general in the Continental Army—without pay.

During his service as the Continental Congress’ secret envoy to France, Silas Deane had, on December 7, 1776, struck an agreement with French military expert, Baron Johann DeKalb, and his protege, the Marquis de Lafayette, to offer their military knowledge and experience to the American cause. However, Deane was replaced with Benjamin Franklin and Arthur Lee, who were unenthused by the proposal. Meanwhile, King Louis XVI feared angering Britain and prohibited Lafayette’s departure. The British ambassador to the French court at Versailles demanded the seizure of Lafayette’s ship, which resulted in Lafayette’s arrest. Lafayette, though, managed to escape, set sail and elude two British ships dispatched to recapture him. Following his safe arrival in South Carolina, Lafayette traveled to Philadelphia, expecting to be made General George Washington’s second-in-command. Although Lafayette’s youth made Congress reluctant to promote him over more experienced colonial officers, the young Frenchman’s willingness to volunteer his services without pay won their respect and Lafayette was commissioned as a major-general.

Lafayette served at Brandywine in 1777, as well as Barren Hill, Monmouth and Rhode Island in 1778. Following the formal treaty of alliance with Lafayette’s native France in February 1778 and Britain’s subsequent declaration of war, Lafayette asked to return to Paris and consult the king as to his future service. Washington was willing to spare Lafayette, who departed in January 1779. By March, Franklin reported from Paris that Lafayette had become an excellent advocate for the American cause at the French court. Following his six-month respite in France, Lafayette returned to aid the American war effort in Virginia, where he participated in the successful siege of Yorktown in 1781, before returning to France and the further service of his own country.

Good morning, Whitewater.

Midweek in Whitewater will be mostly sunny, with a high of seventy-seven, and a one-third chance of showers in the late afternoon. In the city today, sunrise is 5:44 AM and sunset 8:18 PM. The moon is a waxing crescent with twelve percent of its visible disk illuminated.

Sometimes you get the elephant, and sometimes the elephant gets you:

On this day in 1857, a noted theorist is born in Wisconsin:

1857 – Thorstein Veblen Born
On this date economist and social commentator Thorstein Bunde Veblen was born in Cato, although some sources place his birth in Valders. He is best known for his book The Theory of The Leisure Class (1899), a classic of social theory that introduced the concept of “conspicuous consumption.” [Source: The Radical Academy]
