FLIGHT, JANUARY 1, 1932 BOOK REVIEWS " Aerial and Marine Navigation Tables," by John E. Gingrich (McGraw-Hill Publishing Co., Ltd.). Price 13s., post free, from FLIGHT Office. "Our Fathers," by Alan Bott (W. Heinemann, Ltd.). Obtainable from FLIGHT Office. Price 9s., post free. For the Mathematician I IEUTENANT GINGRICH, who at one time was in- *-' structor in navigation at the U.S. Naval Academy, Annapolis, shows us in his " Aerial and Marine Navigation Tables " how he considers that navigation tables should be laid out. Opinions will differ as to the merits and demerits of his ideas, for so many navigators have idiosyn crasies which it is impossible to overcome when the ques tion of table lay-outs is discussed In this new work the author has collected nearly all the tables which can be wanted for ordinary astronomical navigation, whether it be carried out from an aircraft or from a ship, and to do so he has made good use of all available sources of information, such as the well-known authorities, Dr. Ogura, Mr. E. B. Collins and Lt. Com. P. H. Weems. Bound in a flexible cover, it forms one of the most handy books of tables I have seen, but I feel that the type and lay-out might well have been somewhat more open and consequently clearer. Victoriana Rediviva j\flR- ALAN BOTT, well known to all readers of aviation *"•* literature as " Contact," has recently written a most unusual book, entitled " Our Fathers." Under a series of headings he has grouped together a large number of illustrations which, together with the text, give his readers a comprehensive survey of the years 1870- 1900. Many of these, it would seem more by accident than design, well bear out that time-worn adage that " history always repeats itself." In 1886, for example, we are reminded that unemployed rioting was a matter of " brutal violence and infamous rapine." Our present-day generation is far too prone to imagine that this problem is peculiarly their own. Fifty years ago, we find that the costumes worn by British travellers were, as they often still are, " marvels of ugliness," and that, " wherever he goes, the average Briton carries his insular stamp." In 1873, an engraving announces the " Proclamation of a Spanish Republic " . . . and so on. Mr. Bott's text takes the form of a series of revues on the morals ; State, Empire, and international occasions ; the rise of woman ; political and other matters. He writes through modern eyes, as witness his reference to the " Beachcombers " of the period, and at times he mixes humour with sentiment in a divertingly entertain ing fashion, thus linking together the mass of pictorial matter to form what is certainly an unusual, but none the less " well-worth-having," history of the late Vic torian period.
