AERIAL NAVIGATION. 57 



Mr. Alan Macdougall, M. Inst. C. E., F.R.S.E., read a 

 paper on " Aerial Navigation." 



The paper was an exhaustive treatise on the history of ballooning, 

 or aerial navigation, from the earliest days down to the latest experi- 

 ments of MM. Krebs and Renard in 1885. The conclusion the 

 reader came to was that, so far as any success had been attained, it 

 was more in the scientific than the commercial solution of the prob- 

 lem. The number of lives which have been lost of late years is not 

 compensated for by any progress made in the practical solution of 

 aerial navigation.
