SOME ESSEX NATURALISTS 321 The rare moss Zygodon Forsteri is named after him. He was partner with his father in the firm of Edward Forster and Son, and followed his father by becoming a member of the Court of Assistants of the Russia Company and also a director of the Royal Exchange Assurance. His copy of the "Plantae Woodfordiensis" passed into the hands of George Stacey Gibson, who made use of the annotations it contained in his ''Flora of Essex'' published in 1862, and subsequently Gibson gave it to the library of the Literary and Scientific Institution at Saffron Walden, where it now is. It is with the remaining brothers that we are mainly con- cerned. Both spent a considerable part of their lives in this neighbourhood, and their natural history studies are of more interest to us. The second son, Benjamin Meggott Forster, who never married, was essentially a man of science. He contributed plant records to Turner and Dillwyn's "A Botanist's Guide through England and Wales '' which was published in 1805. The Essex section of that guide is very largely the work of these two brothers, Benjamin and Edward junior. In 1820 he published an ''Introduction to the Knowledge of Fun- guses". He was also the inventor of a device known as the Atmospherical Electroscope, which functioned for exactly one year. He was probably involved in the affairs of the family business, and, like other members of the family, he was a philanthropist, a member of the Anti-Slavery Com- mittee, and he was responsible for framing the Child Stealing Act. He was a resident of Walthamstow from a few months after his birth until he died on 8th March, 1829. At the latter end of his life he resided at a house called "Scotts" in Hale End Road. While his botanical notes written in his copy of the Plantae do not disclose the discovery of any rare or strange plants in the district, they are of especial interest in showing the changes which have taken place in the local flora com- pared with conditions at the present day, now that both Walthamstow and Woodford are virtually built-up areas. His observations on some of Warner's notes confirming or doubting the accuracy of the published records, too, are interesting. Benjamin's herbarium of dried plants collected
