These Answers were originally arranged by the writer for use in his school, and to assist him in preparing extra masters, and those desirous of earning the special distinction conferred by the endorsement on their certificates, that the Examination in Compass Deviation had been successfully passed. The recent notification by the Board of Trade, that after the 1st January, 1874, a question will be included in the examination of Ordinary Masters to test their knowledge of the system of compensation by adjustment magnets, suggests that these answers would be valuable to them, as well as to candidates for the higher and honorary grades. The returns of the Registrar General show that these distinctions are now very rarely obtained: and this falling off is generally attributed to the Syllabus of Examination, which requires more time for study than candidates can always conveniently spare, besides that it is also an effort of memory. It is, however, one well worth making, and these answers, embodying, as they do, the result of a good deal of research, will, it is hoped, assist the student in his study of the standard works, which, containing very much more than the necessary information, are nevertheless not designed for this particular purpose. The best are Towson's Practical information, Captain Evans' Mannal, and the Admiralty Manual, and it would be of advantage, if, while studying the subject, a pocket compass and one or two small magnets, together with a few soft iron rods, were always

kept at hand. The intelligent knowledge thereby acquired would enable the candidate to curtail these answers when he thought proper —and while acquiring it, a somewhat dry and tedious study would be made a very agreeable and interesting one.
