Background
John Stevens Henslow was born on 6 February 1796 Rochester, Kent.
From his father, who was a solicitor in that city, he imbibed a love of natural history which largely influenced his career.
(Professor of botany from 1825 until his death, John Steve...)
Professor of botany from 1825 until his death, John Stevens Henslow (1796-1861) revived and greatly advanced the study of plants at Cambridge. His influence helped to make the University Botanic Garden an important centre for teaching and research. Originally published over a period of seventeen years, and now reissued here together, these thirteen papers reveal the impressive breadth of Henslow's scientific knowledge. The first two items, from 1821, address the geology of the Isle of Man and Anglesey respectively, preceding his five-year tenure as chair of mineralogy at Cambridge from 1822. The rest of the papers, dating from 1829 to 1838, address botanical topics. Professor John Parker, Director of Cambridge University Botanic Garden, has provided a new introduction that traces Henslow's developing interests and contextualises the items in this collection. Several of Henslow's other publications, including his Catalogue of British Plants (1829), are reissued separately in this series.

John Stevens Henslow (1796-1861) was a botanist and geologist. As teacher, mentor and friend to Charles Darwin, it was his introduction that secured for Darwin the post of naturalist on the voyage of the Beagle. While Professor of Botany, Henslow established the Cambridge University Botanic Garden as a resource for teaching and research. Students were encouraged to examine plant specimens carefully, and to record the characteristics of their structures. Henslow would have known how daunting they found the task of becoming proficient with botanical vocabulary, and produced this volume to provide a secure foundation for scientific investigations. This meticulous glossary, originally published as a single volume in 1857 but drawing on contributions he made earlier to issues of The Botanist and Maund's Botanic Garden, is a testament to Henslow's scholarship. It is liberally illustrated with delightful woodcuts that clarify the meaning of selected terms.

An influential professor of botany at Cambridge, John Stevens Henslow (1796-1861) revived his department and helped develop the current University Botanical Garden for study, teaching and conservation. A mentor to the young Darwin, he proved an educational innovator, initiating the study of individual sciences at Cambridge and practical examinations at the University of London. While rector of Hitcham in Suffolk, he took an interest in local politics, welfare and popular education. This led to the publication in 1860 of this catalogue, which collated the observations and work of amateur botanists. Henslow was the overarching academic and technical consultant while Edmund Skepper is credited with organising and collating the information from the contributors. Catalogued taxonomically, each plant's Latin and common name is given along with its physical description, common locations, rarity or commonality, and periods of flowering or germination. It remains a valuable guide for amateur botanists and naturalists.

John Stevens Henslow (1796-1861), a student of Adam Sedgwick, became Professor of Mineralogy at Cambridge in 1822. He soon moved to a chair in Botany, and became a teacher and mentor to Charles Darwin. This book on mineralogy was first published in 1823. It was intended to save time in class by providing an easily accessible reference to the composition of various minerals according to the principles of atomic theory, which was then entering the scientific mainstream. In that paradigm, analysis and examination of any mineral's composition involved first ascertaining the mineral's elementary molecules, both 'essential' and 'accidental', and second, determining the proportions in which the essential ingredients combined to form the integrant molecule of the mineral. Henslow's book will interest historians of science tracing the development of atomic theory, and those working more broadly in the history of university education and the intellectual climate of the nineteenth century.

John Stevens Henslow was born on 6 February 1796 Rochester, Kent.
From his father, who was a solicitor in that city, he imbibed a love of natural history which largely influenced his career.
He was educated at the Free School at Rochester and later at Camberwell in Surrey, where his inherent love of nature developed into a keen interest in natural history.
In 1814 he entered St. John’s College, Cambridge, and four years later graduated sixteenth wrangler; he received the M. A. in 1821.
At Cambridge he studied mathematics, chemistry, and mineralogy.
Henslow recommended Darwin as naturalist for H. M S. Beagle and during the five-year voyage regularly corresponded with Darwin and took care of all specimens sent by him.
He went to Cambridge every year to deliver his lectures and he taught botany and horticulture to village children in his parish school.
Henslow’s persistent efforts eventually resulted in the redevelopment of the long neglected Cambridge Botanical Garden, which he regarded as an essential adjunct to the teaching of botany.
He accompanied Sedgwick in 1819 during a tour in the Isle of Wight, and there he learned his first lessons in geology.
In the autumn of 1819 he made some valuable observations on the geology of the Isle of Man ( Trans.
Geol.
He immediately offered himself as a candidate for the position and was elected unopposed.
Soon after, he resigned his chair of mineralogy and devoted himself completely to the study and teaching of botany.
He used his own diagrams and actual specimens at lectures to demonstrate form and structure in plants.
He required students to disse, examine, and describe the specimens they were studying.
As a mineralogist he had used Haüy's laws of crystallography to analyse complex crystals as transformations of "the primitive form of the species" of crystal, and when he moved to botany in 1825 he sought similarly precise laws to group plant varieties into species, often including as varieties plants that respected taxonomists had ranked as separate species.
He followed the understanding of the time that species were fixed as created but could vary within limits, and hoped to analyse these limits of variation.
By a method he called "collation", Henslow prepared sheets with several plant specimens, each labelled with the collector, date and place of collection, comparing the specimens to show the variation within the species.
His A Catalogue of British Plants was first published in October 1829, and became a set book for his lecture course
Four years later he received from the crown the rectory at Hitcham in Suffolk, where he moved in 1839 and resided until the end of his life.
Henslow died on 16 May 1861 at Hitcham.

Henslow was ordained in 1824 and became curate of Little St. Mary’s Church in Cambridge.
He was elected a fellow of the Linnean Society in 1818 and the following year a fellow of the Geological Society of London.
He was also a member of the British Association.
Henslow married Harriet Jenyns (1797–1857), daughter of George Leonard Jenyns and sister of Leonard Jenyns on 16 December 1823.
Their eldest daughter Frances Harriet married Joseph Dalton Hooker, and their youngest daughter, Anne, became a botanical artist.
Their sons included George Henslow (1835–1925), who became the Royal Horticultural Society's Professor of Botany and the first President of the Churchmen's Union for the Advancement of Liberal Religious Thought.
