whole is limited in its action to the use of the individual mem- 

 bers ; it waits upon them, cannot go beyond what they are pre- 

 pared and able to do, is built up of their individual will-- and 

 convictions and desires. 



And it is the same in religion, where individuals aoain 

 surrender themselves as instruments to be used by a divine life 

 which realises its ])urposes through them; so that they become 

 " members in particular " of Christ, and Christ is fulfilled in 

 them. 



Thus the relation of the whole and the parts, of the life 

 and the organism, seems to run t'lrough and throw light on the 

 relation of mind and body in the individual, and in the relation 

 of the individual to the larger spheres.

SoiTH African IxsTmriox of Exgixfers. — Saturday, August 14th: 

 W. Ingham. M.T.C.E.. ALTAT.E.. President, in the chiur.—- Description of 

 collapse and recnrcry of central incline shaft. Bantjes Consolidated 

 Klines, Ltd." : P. Cazalet and W. W. Lawrie. The subsidence was due 

 to a decomposed dyke l)ecoming saturated with water from lieavy rains 

 and being converted into a pla-tic mud. Tlie whole weight of the satur- 

 ated mass was thrown on tlte roof of the shaft, which fractured 

 under the stress. I !n- weiglit was tints transferred on to the 



steel shaft framing. Avliich collapsed with practically no warning'. The 

 steel setts collapsed totally for a distance of 95 feet, and partially for 

 35 feet more. The author proceeded to outline the method of recovery 

 adopted. Travelling timlxr setts were lirst introditced; permanent caps 

 of pitch pine, fitted on the lop with Ixixing. were then placed in i)osition. 

 and finally concrete walls, extending 40 feet above and 45 feet below the fall, 

 or 180 feet in all. were built up, and just two months after the accident 

 hoisting recommenced — " Xotes on Monel metal": E. GofFe. Monel 

 metal, the natural alloy of nickel and copper, reduced from its ores 

 without change of combination, resists corrosion to an extraordinary 

 degree. The author detailed certain tests made m the testing laboratory 

 of the Government Mines Department, which clearly demonstrated the 

 alloy's strength, ductility and toughness. Chemical tests had shown that 

 the action of ordinary mine water on monel metal is inappreciable, that 

 immersion for two days in 3J per cent, sulphuric acid affects the metal only 

 slightly, that a . 12 per cent, solution of potassium cvanide has no greater 

 effect during five day^ immersion, and that free hydrocyanic acid ( .05 

 per cent, solution ) acts on iron with five times greater strength than on 

 monel metal. 



Saturday, October 9th : W. Ingham, M.I.C.E., AI.I.M.E., President, in 

 in the chair. — "Machinery Accidents on the Gold Mines of the Witivaters- 

 rand" : C. B. PattrickC The author furnished tables showing the pro- 

 portions of casualties due to machinery and the number of these classed 

 as preventible, the effects of personal and of impersonal causes in general, 

 and with special reference to preventible accidents. Compensation tables 

 were added showing inter alia, averages per casualty for white and col- 

 oured persons, and for fatal and non-fatal cases. 



Saturday, October 9th : W. Ingham, M.I.C.E, M.I. ALE.. President, in 

 the c\\3.\r.—" Preparation of large type Babcock and Wilcox boilers for 

 test": H.Martin. The author beg^an by describing the construction 

 of the boilers, and then described the preparations made for 

 a large number of test observations and operations, concluding 

 with an outline report on the Victoria Falls and Transvaal Power Com- 

 pany's last official " taking over " test at Brakpan Power Station.
