His leisure time was given up to natural history, and especially to mineralogy and botany. He appears to have been the first to introduce the term "oolithus" to rocks that resemble in structure the roe of a fish;The Jurassic Rocks of Britain: Pub. by Order of the Lords ..., Volume 4 whence the terms "oolite" and "oolitic". He died at Wolfenbüttel.
