||1793: Martin Heinrich Rathke born ... physiologist and pathologist who was one of the founders of modern embryology. He was the first to describe the embryonic precursors of gill slits and gill arches in the embryos of higher animals - mammals and birds - which have none when fully grown. Rathke compared the development of the air sacs in birds and the larynx in birds and mammals. In 1839, he traced the origin of the anterior pituitary gland from a depression in the roof of the mouth, which embryonic structure is now known as Rathke's pouch. Rathke also did pioneering work in marine zoology, as being first to describe lancet fish.

||1852: Simeon North dies ... inventor and manufacturer who, like Eli Whitney, incorporated interchangeable parts in manufacturing. After a start in farming, he began a business making scythes in 1795. He expanded to making pistols, first for private use, then under government contract in Mar 1799 for 400 pistols. Larger government orders followed. By 1813, at North's suggestion, a contract for 20,000 pistols included the provision that parts should be interchangeable. Subsequently, he developed machine tools to aid production. North is generally credited for building probably the earliest, though primitive, milling machine to replace filing operations by about 1816 or even earlier. For 53 years, he filled War Dept. contracts, including rifles (from 1823), and devised a 10-round repeating rifle (1825).

||1865: The Shergotty meteorite falls. It is the first example of the shergottite Mars meteorite family. It was a 5-kilogram (11 lb) Martian meteorite which fell to Earth at Shergotty (now Sherghati), in the Gaya district, Bihar, India on 25 August 1865, and was retrieved by witnesses almost immediately. Radiometric dating indicates that it solidified from a volcanic magma about 4.1 billion years ago. It is composed mostly of pyroxene and is thought to have undergone preterrestrial aqueous alteration for several centuries. Certain features within its interior are suggestive of being remnants of biofilm and their associated microbial communities. | ||1865: The Shergotty meteorite falls.
