 bour was fastened to the extreme front of the tablet in a con- 

 venient place for tapping, and was connected to a more compli- 

 cated recording tambour by a rubber tube, as ordinarily in 

 such cases. Records of the excursions of the pointer of the re- 

 cording tambour were made upon smoked paper which was 

 stretched between two horizontal drums. One of the latter

formed part of an electrically driven kymograph, the other was 

 simple and revolved upon a fixed axis which was supported on 

 two stands by clamps. The two drums were placed on sepa- 

 rate tables which were some 15 to 20 feet apart. The recording 

 tambour as also the time signal were fixed in front of one of the 

 drums to a platform movable in the direction of the axes of the 

 drums. Consequently it was possible by simply shifting the plat- 

 form and thereby the recording apparatus to secure from 4 to 6 

 complete turns of a continuous series of groups, which, with a 

 distance of 15 to 20 feet between the tables, amounted to about
