Bryan Higgins was a natural philosopher in chemistry
Chemistry
Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds....

. His father (d. 1777) was also called Dr. Bryan Higgins. Higgins entered the University of Leiden in 1765, from whence he qualified as a doctor of physics
Physics
Physics is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.Physics is one of the oldest academic...

 amongst others. He was more of a speculator than an experimenter, and published many works on chemistry and related disciplines. Joseph Priestly was an attendee of Higgins's lectures, but the two became enemies following a dispute over experiments on air (Priestly at the time was working on his six-volume tome Experiments and Observations on Different Kinds of Air
Experiments and Observations on Different Kinds of Air
Experiments and Observations on Different Kinds of Air is a six-volume work published by 18th-century British polymath Joseph Priestley which reports a series of his experiments on "airs" or gases, most notably his discovery of oxygen gas .-Airs:While working as a companion for Lord Shelburne,...

Cement
In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. The word "cement" traces to the Romans, who used the term opus caementicium to describe masonry resembling modern concrete that was made from crushed...

Calcium hydroxide
Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca2. It is a colourless crystal or white powder and is obtained when calcium oxide is mixed, or "slaked" with water. It has many names including hydrated lime, builders lime, slack lime, cal, or...

Lime water
Limewater is the common name for saturated calcium hydroxide solution. It is sparsely soluble. Its chemical formula is Ca2. Since calcium hydroxide is only sparsely soluble, i.e. ca. 1.5 g per liter at 25 °C, there is no visible distinction to clear water. Attentive observers will notice a slightly...
