For any given R (resistance of the line) the currents can be increased 

 by selecting a dynamo-electric machine with the right internal resistance. 



The advantages of the method aj^peared to me sufficiently great to 

 justify a practical trial : — 



Experiment, October 11, 1879. With a Siemens's dynamo-electric 

 machine (medium size) I produced a powerful electric liglit ; and between 

 the poles of the dynamo-electric machine I connected up four artliicial 

 lines, each of 10,000 units resistance, with relaj^s ranging between 500 to 

 1000 units. These four parallel circuits worked very well, singly and 

 simultaneously. No variation of the electric light during telegraphing 

 could be noticed, even when the line resistance was reduced to 1000 units. 

 Further, the resistance of one line was increased to 20,000, and the 

 signalling currents were still sufficiently strong (1'6 milli-oerstedts). 



Experiment, October 14, 1879. Same as above ; but a branch current 

 was conveyed by the store-yard line (from the store-yard where the dynamo- 

 electric machine with its electric light was put up) to Calcutta signalling- 

 office (4 miles), and one of the Agra lines (850 miles in length) worked by 

 this current. 



The sent current, measured at Calcutta, was 9'6 milli-oerstedts; the 

 received current, measured at Agra, 1'85. The great loss was due to the 

 exceedingly low insulation of the line near Calcutta. It is now the break- 

 ing up of the monsoons, when the climate in lower Bengal represents almost 

 a hot vapour bath. 



Several messages were sent to Agra, but no variation in the electric 

 light could be observed. 



II. — On tlw Occurrence of the Music-Deer in Tibet. 

 By R. Ltdekkee, B. A. 

 (Received November 17tli, 1879.) 



Some degree of doubt seems, hitherto, to have prevailed among natura- 

 lists whether the Musk-Deer (Moscliiis) occurs on the Tibetan plateau, or 

 whether it is confined to the wooded districts of the Alpine Himalaya. 

 Thus in a paper contributed by Mr. W. T. Blanford to the ' Proceedings 

 of the Zoological Society of London,'* the author says that he has grave 

 doubts whether the Musk-Deer occurs anywhere on the Tibetan plateau. In 

 a paper published by myself in the Society's Journal,! I mentioned that, 

 from having seen skins in Ladak, as well as from the fact of the Ladakis
