Researches on tlie Distribution of the Mean Motions of the Asteroids. 5I 



Two asteroids (401) and (528) seem to make the libration of Type 

 1, but as the difference of E and F^ is very small the motion may 

 be changeable to the revolution of Type 1 depending on the 

 amount of the smaller inequalities. The asteroid (777) has a 

 negative value of C and the motion is the libration of Type 2. All 

 the remaining 38 asteroids make the revolution of Type 1 or 

 Type 3. 



62. For the class 3/2 six asteroids only may be taken. The 

 results of computation are as follows: —

Five asteroids out of six have negative values of C and make the 

 libration of Type 2. The asteroid (334) makes the libration of 

 Type 3 with a positive value of C

 the following result: —
