Perhaps the greatest fame of the Cambridge Press rests upon its mathematical typography. To glance at a page, say, of _Principia Mathematica_ is to realise a little--but only a little--of the minute care and skill required of the compositor, the press-reader, and the machine-minder in the production of such a book. It may be permissible here, perhaps, to quote one recent tribute from the preface to Professor E. W. Brown's _Tables of the Motion of the Moon_, printed in 1918 for the Yale University Press: The reading of the proof has been almost entirely directed to the detection of errors in the manuscript. That this has been possible is due to the remarkable record of the Cambridge University Press which in setting up over five hundred quarto pages of numerical tables has allowed less than a dozen printer's errors to pass its proof-readers and has, in addition, frequently queried our own mistakes. Few sheets have required a second proof and in the actual use of the Tables, as finally printed, for the calculation of the ephemeris for two years, no error of any kind has been detected. On the retirement of Mr George Seeley in 1856, Messrs Hamilton, Adams & Co., of Paternoster Row, were appointed as agents for the Syndics' books[139]. This arrangement, however, does not seem to have been satisfactory, as the name of a new agent--George Cox--appears in the following year; a further change was made in 1862 when the firm of Rivingtons became agents for Cambridge books; finally, when this agreement came to an end, ten years later, the Syndics reported to the Senate that "acting on the advice of Mr Clay" they had decided "not to appoint other Agents, but to conduct their London business in an office of their own, under the superintendence of a paid Manager" and that they had agreed "to take a Lease of convenient premises in Paternoster Row." The beginning of the Syndics' career as London publishers--in the strict sense of the term--must therefore be assigned to the year 1872. At that time the number of books published by the Syndics--apart from bibles and prayer-books--was very small. Among them, however, may be noted the first volume of Mullinger's _The University of Cambridge_, published in 1873, the first instalment of a monumental work which remained uncompleted at the author's death in 1917. In 1874 an important step was taken, the Syndics deciding to publish a series of editions of Greek, Latin, French, and German authors designed for use in schools and especially for candidates for the Local Examinations. This was the beginning of the Pitt Press Series, which now includes over 300 volumes, and such editions as Sidgwick's _Virgil_ and Mr Verity's _Shakespeare_--to name but two out of many--have become familiar to many generations of schoolboys.
