140 Proceedings, <&a, for 1883. 



The class in every case calculated the weight the model ought 

 theoretically to carry, and the breaking weight usually agreed very 

 closely with the calculation. Three models were exhibited, the first 

 weighing 25 oz., yet breaking with the weight of 208 lbs. This 

 form of girder was common enough in the colony. The second 

 model weighed 21 oz., and broke with a weight of 771 lbs. The 

 third model was an actual representation of the girders used in the 

 Victoria-street Bridge. It was 45 inches long, weighed 34 oz., and 

 broke with a weight of 1627 lbs. A number of models of girders 

 designed by various eminent authorities had been made and tested 

 at the University, but the Victoria-street girder was better than the 

 best of these by more than 30 per cent. 



Mr. T. B. Muntz thought that much credit was due to Professor 

 Kernot for this efficient manner of teaching engineering, and also 

 for the valuable results of these experiments. 



August 9 th , 1883. 

 The President in the chair— Present, 26 members and associates. 



Capt. F C. Rowan and Mr. C. F. Rennick were introduced, and 

 signed the members' book. 



Mr. R. E. Fletcher and Mr, G. Smibert were elected associates. 



The President said that a number of students of engineering at 

 the University were desirous of becoming associates of the Society 

 for the purpose of joining Section A. As the year was advancing, 

 he would propose that the Standing Orders be suspended to admit 

 of their being elected at once ; this was accordingly done, and the 

 following gentlemen were elected associates: — L>. C. Askew, T. 

 Murray, A. W. L. Paul, W. R. Rennick, B. A. Smith, G. Wight, 

 A. M. Grant, J. B. O'Hara, W. H. Brockenshire, L. L. Murray, 

 N. E. Phillips, E. Shaw, U. Tyers, F. S. Grove, C. G. V. Williams, 

 G. H. Dunlop, N. J. Noall, E. C. Rennick, E. L. Smith, H. W. L. 

 Tisdall, L. Clark, F. S. Brush. 



Mr. Blackett then read a paper on " Schone's New System of 

 Sewage." 



Mr. Kernot said that his first impression on hearing the description 

 of this new system was that it was too good to be true ; it evidences 

 an immense deal of originality and ingenuity in every particular. 

 Mr. Blackett said that Schone's system had nowbeenin use for two 

 years at Eastbourne, where satisfactory results had been obtained, 

 and the scheme had therefore passed beyond the experimental 

 stage. 



Mr. Cosmo Newbery read his paper "Notes on Tin Ore Dressing." 

 Dr. MacGillivray read his paper, " Descriptions of New, or Little 

 Known, Polyzoa," Part V.
