My dear Sir.
I am extremely obliged to you for both your notes.1
The case2 has arrived & I hope its contents will be turned to good account.
I have forwarded your note3 to Ipswich4—if the rotating frame reach me any time before Wednesday next it will be quite early enough.
Thank you very much for your kindness
believe me | most sincerely yours | John Tyndall
