204 DIMINUTION OF THE WATER OF RIVERS AND STREAMS. 



4. The Eoyal Academy should express to th'e government the wish 

 that in more streams, and in better adapted places, regular observations, 

 not only of the water-heights but also of the whole amount of water 

 flowing through a stream, might be made, in order that the i)roportion 

 between the latter and the water-heights may be at least approximately 

 obtained. 



The government, furthermore, should endeavor to draw the attention 

 of the Hungarian and other foreign governments to the wish of the 

 Royal Academy, that similar observations and inquiries might be insti- 

 tuted in other countries.
