of the questions to which he has given written answers, in further illustration of its meaning. Vivâ voce questions will be asked on the answers given.
136. In the questions on the Deviation of the Compass the examiner will mark at least twelve of the questions, including the problems. The selected questions will be varied frequently, and no two Candidates will have precisely the same questions. The Candidate will be furnished with sheets of the blank ruled paper which is supplied for the purpose, with instructions that he is to write only on one side of the paper, and to answer in a clear and legible hand each of the questions against which a mark is placed, and to commence each answer by writing down the number of the question to which it relates in the margin. In answering Question 39 on the tentative method of compass adjustment, the Candidate will be tested by Beall's Compass Deviascope, and it will not there- fore be necessary for him to give the written answer and sketches.
187. The examination on the barometer, thermometer, and hydrometer, prevailing winds and currents of the globe, trade routes, and tides, will for the present be conducted orally, and the questions asked by the examiner, which will be constantly varied, will be confined to and based on the information given in the text books mentioned in Appendix A. Candidates will be required to have a fair and intelligent knowledge of the contents of those books.
138. Particular attention should be paid to the adjustments of the sextant, the examination in which subject will be conducted orally and practically. Every Candidate will be examined prac- tically as to his knowledge of the adjustments and the use of the various screws; he must be able to read correctly off the arc, a supposed index error being given by the examiner as additive, as well as reading on the arc in the usual way; he must also be able to find the index error both by the horizon and by the sun.
139. Candidates will find it more convenient, both during the examination and at sea, to correct the declination and other elements from the Nautical Almanac by the hourly differences given in that work; they will thereby render themselves independent of any proportional or logarithmic table for that purpose.
140. The corrections by inspection of tables given in some of the works on Navigation, e.g., Tables IX., XI., and XXI. in Norie's Epitome, will not be allowed; every correction must appear on the papers of the Candidates.
141. All outstanding or minor corrections should appear in the margin of each problem paper and on the chart papers, and the papers of the Candidate will not be considered complete without these corrections.
142. Examiners should bear in mind that the problems to be solved are required as tests, and for the purposes of an examination, and not for sea-going or practical purposes alone.
143. Candidates will be allowed to work out the various pro- blems according to the method and the tables they have been accustomed to use.
144. All the problems given in the examinations, for the Ordinary Certificates, will be constantly varied; and the mode of stating the times in the astronomical problems, and the mode of wording and setting these and all other problems will be varied in every possible way, so as to ensure that the Candidate has a proper knowledge of the subject.
