the same undulations as the first plate, and it would therefore be the same as if a 

 person had spoken in the immediate neighborhood against this second plate, or 

 the ear would be affected in the same manner as if it received the tones commun- 

 icated through the first metal diaphragm {)neftallwand=vfz\\, partition, E. B.). 

 The electrical telegraphy which at the time was stamped, academically, almost as 

 nonsense, now traverses the whole world as a familiar phenomenon. If we con- 

 sult, in regard to this new idea of a young physicist, the principles of physics, we 

 have not only nothing to say against the possibility of its execution, but its suc- 

 cess seems more probable than did electrical telegraphy not long ago. 



If the experiment succeeded, then electrical telegraphy would have become 

 quite good ; it would require no other machinery and knowledge than a galvanic 

 battery, two vibratory plates and a metal wire ; without further preparation one 

 person would have only to speak against the one metal plate and the other per- 

 son to hold his ear to the other, and thus they could converse one with the other 

 as under four eyes {unter vier a2^^<?«=personally). 



The young inventor believes in the success of his endeavors, and challenges 

 the learned men to prove that the laws of physics are in contradiction with the 

 above recited principles, and that they let appear impossible what is looked for. 



In the meantime this matter would deserve the attention it will receive, in 

 the highest degree.

METEOROLOGY. 



METEOROLOGICAL DISCOVERIES. 



ISAAC P. NOYES. 



Discovery is the act of obtaining facts in regard to any subject. The great 

 discoverers of the world are they who have ascertained facts in relation to the 

 conditions of nature. The higher the type of the discoverer the more cause 

 and effect will enter into his composition, and the more his work will reveal it. 

 Not only will he seek to discover facts, but also the relations which these facts 

 bear to each other and the results of their influence upon the forces of nature. 

 No matter how capable a discoverer may be, no matter what his powers of 

 mind and body, he is more or less hampered by his surroundings. 



The globe on which we live, even at this late day is not entirely discovered, 

 and although the undiscovered portions are comparatively small, no one at pres- 

 ent can tell what influence their discovery will have upon the human race. 



Although the world was highly civilized and had, centuries ago, made astro-
