Lant is aged urine. The term comes from Old English hland , which referred to urine. [1] Collected urine was put aside to ferment until used for its chemical content in many pre-industrial processes, such as cleaning and production. [2]
Because of its ammonium content, lant was most commonly used for floor cleaning and laundry. According to early housekeeping guides, bedpans would be collected by one of the younger male servants and put away to ferment to a mild caustic before use.
In larger cottage industries, lant was used in wool-processing [3] and as a source of potassium nitrate for black powder. In times of urgent need and in districts where these were the chief industries, the whole town was expected to contribute to its supply.
"Lant. Stale urine. It was preserved in a tank and having been mixed with lime used for dressing wheat before it was sown to keep the birds from picking up the seeds."
LaNt (with an alternate capitalization) may also refer to Laminin N-terminus proteins. [5] Laminins are basic structural proteins of basement membranes. Some particularly small sized proteins within this family of proteins are called LaNt proteins.
Hallamshire is the historical name for an area of South Yorkshire, England, approximating to the current City of Sheffield local government area.
Bowman's capsule is a cup-like sac at the beginning of the tubular component of a nephron in the mammalian kidney that performs the first step in the filtration of blood to form urine. A glomerulus is enclosed in the sac. Fluids from blood in the glomerulus are collected in the Bowman's capsule.
A renal corpuscle is the blood-filtering component of the nephron of the kidney. It consists of a glomerulus - a tuft of capillaries composed of endothelial cells - and a glomerular capsule known as Bowman's capsule.
The glomerulus is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons. The tuft is structurally supported by the mesangium, composed of intraglomerular mesangial cells. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The filtrate then enters the renal tubule of the nephron.

Laminins are a family of glycoproteins of the extracellular matrix of all animals. They are major constituents of the basement membrane, namely the basal lamina. Laminins are vital to biological activity, influencing cell differentiation, migration, and adhesion.
This timeline of Sheffield history summarises key events in the history of Sheffield, a city in England. The origins of the city can be traced back to the founding of a settlement in a clearing beside the River Sheaf in the second half of the 1st millennium AD. The area had seen human occupation since at least the last ice age, but significant growth in the settlements that are now incorporated into the city did not occur until the Industrial Revolution.

Urine is a liquid by-product of metabolism in humans and in many other animals. In placental mammals, urine flows from the kidneys through the ureters to the urinary bladder and exits the urethra through the penis or vulva during urination. In other vertebrates, urine is excreted through the cloaca.

Pemphigoid is a group of rare autoimmune blistering diseases of the skin and mucous membranes. As its name indicates, pemphigoid is similar in general appearance to pemphigus, however unlike pemphigus, pemphigoid does not feature acantholysis, a loss of connections between skin cells.
The Limb Brook is a stream in Sheffield, South Yorkshire, England. It rises at the village of Ringinglow, flowing east through Whirlow and Ecclesall Woods into Abbeydale in the Beauchief area, where it merges with the River Sheaf.

40S ribosomal protein SA is a ribosomal protein that in humans is encoded by the RPSA gene. It also acts as a cell surface receptor, in particular for laminin, and is involved in several pathogenic processes.
Hoober Stand is a 30-metre-high (98 ft) tower and Grade II* listed building on a ridge in Wentworth, South Yorkshire in northern England. It was designed by Henry Flitcroft for the Whig aristocrat Thomas Watson-Wentworth, Earl of Malton to commemorate the quashing of the 1745 Jacobite rebellion. It lies close to his country seat Wentworth Woodhouse. Its site is approximately 157 metres (515 ft) above sea level and from the top there are long-distance views on a clear day. Hoober Stand is one of several follies in and around Wentworth Woodhouse park; the others include Needle's Eye and Keppel's Column. Sidney Oldall Addy, the Sheffield author calls the structure Woburn Stand in his 1888 book, A glossary of words used in the neighbourhood of Sheffield.
The Wicker is an arterial street in Sheffield, England noted for its history and viaduct that crosses it, the Grade II* listed Wicker Arches. It runs in a north-east to south-westerly direction between Lady's Bridge and the Wicker Arches.

Sidney Oldall Addy was an English author of books on folklore and history. He was born in Norton, Derbyshire, to coal merchant and landowner James Addy and his wife, Sarah. He studied classics at Lincoln College, Oxford, before becoming a solicitor. In 1899 he married Mary Golden Parkin.
A little mester is a self-employed worker who rents space in a factory or works from their own workshop. They were involved in making cutlery or other smallish items such as edge tools. The term is used almost exclusively to describe the craftsmen of the Sheffield area, and is mostly archaic as this manner of manufacture peaked in the 19th century and has now virtually died out. Little mesters either worked alone or employed a small number of workers and/or apprentices.
