The National Soil Archive of Scotland, held at the Aberdeen campus of the James Hutton Institute, has added two large samples of Dopplerite to its collection by gift of the executors of Mr William Filshie. Dopplerite is a naturally occurring, but relatively rare, organic material associated with peat deposits. It is a jelly-like, brownish substance related to humic acids that is insoluble in water and, if dried, it initially becomes brittle and eventually becomes as hard as coal.
