Thanks for letter and advice. Has been able to get copies of William Parsons' (3rd Earl of Rosse) papers. Would like advice on the size of the grinding tool. Hopes to avail himself of JH's invitation to visit Collingwood.
Has now succeeded in grinding his 20" speculum and it is ready for polishing. Would like to see the mounting of JH's telescope as it is not clear from the engraving.
Is grateful for JH's offer of assistance and proposes to visit him next Wednesday. Congratulations on the addition to his family.
Has been unable to return the papers as he has been so busy. Proposes making working drawings as he suggests. Will take the papers to the Dover Railway to ensure their safety.
Encloses the tickets for the Philharmonic concerts and gives details of the program. Is going to cast another 20" speculum in a few days.
Did not realize that JH would leave town so quickly. Cast a 10" speculum successfully after William Parsons' (3rd Earl of Rosse) plan. Is having difficulty with his grinding and polishing and would welcome JH's advice.
