"In 1662, the newly formed 'Royal Society of London for Improving Natural Knowledge' was granted a charter to publish by King Charles II and on 6 March 1665, the first issue of Philosophical Transactions was published under the visionary editorship of Henry Oldenburg, who was also the Secretary of the Society. The first volumes of what was the world's first scientific journal were very different from today's journal, but in essence it served the same function; namely to inform the Fellows of the Society and other interested readers of the latest scientific discoveries. As such, Philosophical Transactions established the important principles of scientific priority and peer review, which have become the central foundations of scientific journals ever since."
The early years of the Philosophical Transactions were not published yearly as today. The first twelve volumes were printed as abridged volumes from the years 1722 to 1756 and cover the Philosophical Transactions from its inception in 1662 to until 1750. This is volume ten, part II in this case (part I covered the first two parts, this volume parts III and IV as noted).
