Light and Heat.

From the Buffalo Courier. 



Scientists have practically ignored the 

 existence in nature of two distinct forms 

 of light and heat. This two-fold divi- 

 sion is clear and demonstrable, yet in- 

 vestigators in these fields have made too 

 little account of it in their reckoning. 

 The failure to recognize this fact has 

 been the source of errors and confusion 

 in our philosophy of these forces. The 

 two forms while possessing certain pro- 

 perties in common, have yet other pro- 

 perties quite dissimilar. Different in the 

 manner of their production and in their 

 effects, it is a question whether they are 

 not essentially different in their nature. 



The first form, that of combustion 

 light and heat, is .dependent for its pro- 

 duction upon the combustive destruc- 

 tion of inflammable materials due to the 

 action of oxygen. Examples of this form 

 are the lights and fires of our homes. 



The second form we term magnetic 

 in the production of which oxygen has 

 no part. Examples of this form are the 

 magneto-electric and the dynamo-elec- 

 tric processes the latter of which is 

 pre-eminently the topic of the day. The 

 peculiarity of this form is that light and 

 heat are not necessarily manifested at 

 or near the seat of production, but exist 

 potentially, their development as light 

 and heat being effected wherever the 

 proper conditions are provided. This 

 magnetic force, while permitted to flow 

 freely through a perfect conductor is 

 never developed into light and heat, but
