John Edward Gray wrote nearly 500 papers, including many descriptions of species new to science. These had been presented to the Museum by collectors from around the world, and included all branches of zoology, although Gray usually left the descriptions of new birds to his younger brother and colleague George. Gray was also active in malacology, the study of molluscs. John Edward Gray was buried at St Mary's Church, Lewisham. Gray was one of the most prolific taxonomists in the history of zoology.

Interface and colloid science and cannot be seen by the naked eye. They easily pass through filter paper. But colloidal particles are big enough to be blocked by parchment paper or animal membrane. Interface and colloid science has applications and ramifications in the chemical industry, pharmaceuticals, biotechnology, ceramics, minerals, nanotechnology, and microfluidics, among others. There are many books dedicated to this scientific discipline, and there is a glossary of terms "Nomenclature in Dispersion Science and Technology," published by the US National Institute of Standards and Technology (NIST).
