John Ponsonby wrote to Frederick Hervey Foster Quin in August 1830:
‘Your letter shows that you are far from the proper degree of confidence in the permanent tranquillity of Paris. I think you will have your throat cut in 1832, about midsummer. I see Seneca Dupin has been successfully lecturing the young sovereign; he had better turn his thoughts to the comfortable rewards his predecessor received for his wise counsels’….
‘I cannot tell you how much pleasure it gives me to hear from you; the statements of facts you furnish me with are very interesting, and certainly your views of the state of affairs equally so.
‘I consider the game to be only now at the beginning; I will hope, if you please, that the trumps may continue in the same hands to the finale of the party, but I cannot expect it. Similar causes, it is said, and philosophy is a la mode, always produce similar effects; I think I see clearly that those causes now exist and operate in France which I have always seen, followed by disastrous consequences everywhere.
‘I am delighted to hear of the prospect of homeopathy; I am surprised whenever I find truth in vogue. Mr. – seems to be in high spirits, and he tells me that his general health is miraculously good, which he attributes to homeopathy.
‘I spent some hours with Lord – yesterday; he is here for change of air, and quite in exstacies about France; how little I value the judgment of violent party men, be they Whig or Tory.
‘I recommend you to the article in the July Edinburgh Review concerning Jefferson, merely to see what He and Washington, and Adams, and Hamilton thought of the American Constitution, it is curious.
John Ponsonby wrote to Frederick Hervey Foster Quin on 6.10.1830:
‘Are you so very well founded in believing yourself free from the danger of having your place pre-occupied in London? I particularly esteem it right you should be in London as soon as may be after if not at the meeting in Parliament.
‘It is the moment for an introduction. My only scruple heretofore about giving you the most open and strong advice was derived from the state of your fortune; now that I know it will suffice you for 8-10 years as it is, I have no hesitation to say stoutly go to London; ‘try your luck, or rather show your science; if you fail, what then, you can only fail by the failure of homeopathy; you know that to be true, and that it cannot fail; but if it should prove false you are too honest a man not to be amongst the first to declare it to be so, and too acute not to find out its fallacy as soon as any other man whatever.
‘You can then fall back to where you have been, and I think with advantages’.
John Ponsonby wrote to Frederick Hervey Foster Quin on 2.11.1830:
‘My Dear Doctor Quin, I think the late trial of St. John Long will be, absurd as it is, a disadvantage to you at this moment, and should you come to London, but a little time will force you from Paris; should I see an opening here I will immediately write to you. I am anxious to speak to Lord Anglesey (Henry William Paget Marquess of Anglesey), and have not yet seen him’….
‘I do not sympathise in your objections to the infra dig. of vending your own medicines, if by so doing you can avoid the noxious provisions of a foolish statute. There is no descending when the end and object is to advance science and promote human welfare.
‘Everybody may be made to know why you assume the status of apothecary, and to what point you limit the exercise of your profession; you will be in fact what you are – MD. Don’t sacrifice things to mere words’.
John Ponsonby wrote to Frederick Hervey Foster Quin in April 1832:
‘Dr. Belluomini (Guiseppe Belluomini) is arrived here, and has brought recommendatory letters to many persons. I am told he has not had personal experience of cholera, but says camphor is the proper remedy. Send me your memoire…. (Ponsonby used camphor to treat cholera himself),
‘I am not certain of the advantage to be derived from addressing your pamphlet (on cholera) to the Board of Health. I do not imagine that a work on such a subject as cholera, and which exhibits to the World a new method of cure for that complaint, and which has been proved by experience to be at least in numerous cases effectual, will stand in need of any thing beyond its own intrinsic importance to make it an object of universal attention of all manner of men’,
