The value of placing a prism in front of the lens to obtain 

 spectra is also mentioned, and it is recommended that the plate 

 be kept in vibration at a known rate. Prof. Pickering thinks 

 that using three plates each night it would be possible to deter- 

 mine the altitude, radiant point, velocity and spectrum of one- 

 third of all the bright meteors visible in any locality.
