That the export of Scottish engineers and engineering teachers to Japan in the 1870s aided that country's astonishingly rapid process of modernization from a feudal to a capitalist, industrialized society will not occasion surprise or dissent. As the Japan weekly mail editorialized in 1878: In no direction has Japan symbolised her advance towards assimilation of the civilisation of the Western world more emphatically than in that of applied science.

It is well known that Richard Hakluyt in a publication of 1581 congratulated Sir Walter Ralegh for employing Harriot to teach him and his many sea captains the sciences of navigation. Even more important, however, was the navigational research carried out by Harriot on behalf of Ralegh. He made important theoretical advances in map theory and in navigational astronomy, carried out the astronomical observations needed for a reform in navigational tables, and designed and himself tested at sea improved navigational instruments. Harriot had many other responsibilities in connexion with Ralegh's enterprises. From August 1585 to June 1586 Harriot was in Virginia, and in 1589 he was listed as one of Ralegh's colonists in Munster. He collected intelligence concerning America for Ralegh, and his publication of 1588 was effective as propaganda for Virginia. Harriot was also entrusted with financial, and even political responsibilities by Ralegh. Instructing Ralegh and his captains in navigation was an important part of Harriot's work but it is more likely that he did this as the occasion demanded, rather than on a regular basis.

Although the University of Leeds has attained something of a reputation for the quality of its scholarship in the history of science, few historians are aware of the impressive collection of early scientific and medical books and manuscripts to be found in the University libraries. In order to make the library resources more widely known, we embarked on a systematic survey of the contents of the main historical collections. We wanted not only to give a general impression of the particular strengths and distinctive features of each collection, but also to mention the interesting or rare copies of individual works to be found in them. We have, therefore, examined every book related to the history of science and medicine in the relevant collections, and in doing so we have uncovered a number of important items. For example, we have identified a book which was once in Newton's library, and a previously unrecorded copy of Joseph Black's chemical lectures. More generally, we had not suspected the true size and range of the Chaston Chapman Collection, which makes it a valuable resource for the history of alchemy and early chemistry; nor were we initially aware of the strength of the Historical Collection of the Medical and Dental Library. The wealth of the legacies to (and the discrimination shown in recent purchases for) the Brotherton and Special Collections also impressed us.
