of the laws which govern the length of the continuous part. I 

 shall limit myself here to the production of two of these series ; 

 they consist of those which Savart adopted as his type, and from 

 which he deduced his laws. The following are the tables con- 

 taining them : — 



and the first shows, that with an orifice of 6 millims., the pro- 

 portion of the length of the continuous portion to the square 

 root of the charge appears to have attained its limit even with a 

 charge of 27 centims. ; the slight increase manifested in the case 

 of the succeeding charge is undoubtedly due to the causes of 

 irregularity which I have mentioned. 



Let us further calculate, for these two series, the proportions 

 of the lengths corresponding respectively to the two orifices, 

 which gives us the following table : — 



It is therefore also under the charge of 27 centims. that the pi-o- 

 portion of the lengths of the continuous portions attains that of 

 the diameters of the orifices, which completes the establishment 

 of the conformity of the conclusions of § 79 to the results of ob- 

 servation. 



Lastly, with an orifice of 3 millims., Savart has made a series 

 of observations corresponding to four larger charges than the pre- 

 ceding, and the proportion of the length of the continuous por- 

 tion to the square root of the charge still appeared perfectly 

 constant; the first of these new charges was 51, and the last 

 459 centims. 



82. Thus, as we have been taught by Savart's investigations, 

 the vein gives rise to the production of a continuous sound,
