510 BIBLIOGRAPHY OF HERSCHEL^S WRITINGS. 



It is not supposed that such synopses as these will replace the origi- 

 nal memoirs for the professional astronomer and physicist. The works 

 of a great philosopher to be truly mastered must be studied in the 

 form in which he gave them. Yet those who are most familiar with the 

 originals will find the present volume most valuable. 



The full subject-index will direct attention to special points. It is 

 hoped that the work in its present form wiU be of service in various 

 ways, which do not need suggestion here.
