However, Graham found that when crystals of the neutral phosphate were heated, all but one of the water molecules in the crystal were readily lost (these were the water of hydration) and the last unit of water was not lost until the temperature was much higher.

 The Late Professor Graham : Nature
Graham was born at Glasgow, on the 21st December, 1805, the eldest of a family of seven, of whom only one survives.
Graham justly argued that if the decomposition were due to the tension of ether vapour, it could not take place, and ether would not be formed, if the tension were not allowed to exert itself.
Graham's scientific influence extended beyond his researches; for, on the one hand, his lectures for 18 years at University College were remarkable for logical accuracy and clearness of exposition, and were highly valued by those who had the privilege of hearing them.

Thomas Graham was born in Glasgow in 1805.
Graham was fascinated by the motion of atoms in gases and liquids, and spent most his time studying the diffusion of gases, and undertaking a study of the nature of phosphates.
Graham's investigations of the behaviour of crystallised compounds passing through membranes, as a method of separating large molecules from similar compounds, led to the technique of dialysis.

 How it works
Colloidal chemistry was pioneered by Thomas Graham, a British chemist, over 100 years ago, but only recently has it been realized by scientists what an enormous influence it is destined to have in medicine, agriculture and industry.
Graham was at the time Master of the Mint of England, an office once held by Isaac Newton toward the end of the 17th century.
Graham wrote in 1861: "As gelatine appears to be its type, it is proposed to designate substances of the class as colloids, and to speak of their peculiar form of aggregation as the colloidal condition of matter."

1805–69, Scottish chemist, best known for research in diffusion in both gases and liquids that led to his formulation of Graham’s law.
His discovery that certain substances (e.g., glue, gelatin, starch) pass through a membrane more slowly than others (inorganic salts, e.g., common salt, or sodium chloride) led him to draw a distinction between the two groups, calling the former (the slower) colloids and the latter crystalloids.
His investigation of phosphoric acid led to the present chemical concept of polybasic acids.

From 1828-1833 he studied diffusion of gases and in 1833 proposed Graham's Law, which states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular weight.
Graham also found that substances of these two types differ markedly in their ability to pass through a membrane such as parchment paper or collodion.
Graham thought that there was a deeper difference between ordinary, easily crystallizable substances and the slowly diffusing, nondialysing substances, which he was unable to crystallize.
