PROTO-BATHYSPHERES 6$ 



different purposes. How he was to take this structure to 

 a mile depth in the sea he does not mention. 



The hst grows and each inventor adds a novelty or 

 speaks of unknown former proposals with utmost enthu- 

 siasm — Petit, Merlo, Deeman, Hopkins, Ceretti, Russell — 

 we cannot give them all. But we must notice among them 

 Houdini who patented a housing "which can be got into 

 or out of in any position or in any situation." Intrepid, 

 delightful Houdini! The worst scheme was proposed by 

 Mr. Freeze, who suggested several concentric cylinders, 

 one of which he keeps rotating. The reason for this was Mr. 

 Freeze's secret and that he was serious is shown by his pro- 

 vision of a gyrostat to maintain stability. 



Our review may well end here, for while a host of 

 modern inventors have contributed a bewildering maze of 

 patented gadgets yet no single engine or suit was signally 

 successful beyond all others. 



When the bathysphere was finally developed, the key 

 to successful operation was found to be sheer simplicity. 



Given the knowledge of steel and the fusing of quartz, 

 of the use of oxygen and rubber, and the achievement 

 was not difficult. The window to a wholly new world was 

 opened at last to human eyes.
