Summary:
Has never seen the fair copy of William Herschel's polishing book. Will be pleased to assist Wilhelm Struve regarding the Standards. Will ask George Everest to call on him and discuss the Indian operations. How did Herschel perfect the adjustment of his object glass? Has been experimenting with the Josef Fraunhofer spots.
