IT is natural to find that a large portion of the presidential address delivered before the Institution of Mechanical Engineers by Prof. H. S. Hele-Shaw on October 20 should deal with education, research, and scientific knowledge and invention, in all of which the president himself has played an important part. The Institution has now before it the results of the first year's work in the examinations for national certificates and diplomas. These examinations are conducted by the technical schools, together with assessors appointed by the Institution, who are responsible for considering all papers and for reviewing and supervising all results. All the results are submitted to a joint committee of the council of the Institution and the Board of Educa tion, and all border-line cases are specially considered. It is of interest to note that in more than one case the Institution has had to modify the severity of the school, which is far more satisfactory than if technical schools desired to pass their candidates too easily. Of the 1250 candidates drawn from forty-eight technical schools, fifty-one per cent, have been awarded various grades of national certificates and diplomas. The Institution does not appear as yet to be ready to give a decision as to whether these examinations will be accepted in lieu of the Institution's own examinations for associate membership, although the matter appears to be under consideration.
