"You will be glad to learn, my dear daughter, that your father's health was never so good, and probably before this reaches you he will be on the ocean on his return. I think of leaving Paris in a very few days. I am only waiting to show the Telegraph to the King, from whom I expect a message hourly. The birth of a prince occupies the whole attention just how of the royal family and the court. He was born on the 24th inst., the son of the Duke and Duchess of Orleans. My rooms are as delightfully situated, perhaps, as any in Paris; they are close to the palace of the Tuileries and overlook the gardens, and are within half a stone's throw of the rooms of the Duke and Duchess of Orleans. From my balcony I look directly into their rooms. I saw the company that was there assembled on the birthday of the little prince, and saw him in his nurse's arms at the window the next day after his birth. He looked very much like any other baby, and not half so handsome as little Hugh Peters. "I received from the Minister of War, General Bernard, who has been very polite to me, a ticket to be present at the _Te Deum_ performed yesterday in the great cathedral of Paris, Notre Dame, on account of the birth of the prince. The king and all the royal family and the court, with all the officers of state, were present. The cathedral was crowded with all the fashion of Paris. Along the ways and around the church were soldiers without number, almost; a proof that some danger was apprehended to the king, and yet he ought to be popular for he is the best ruler they have had for years. The ceremonies were imposing, appealing to the senses and the imagination, and not at all to the reason or the heart." The king was Louis Philippe; the little prince, his grandson, was the Count of Paris. "_Paris, September 29, 1838._ Since my last matters have assumed a totally different aspect. At the request of Monsieur Arago, the most distinguished astronomer of the day, I submitted the Telegraph to the Institute at one of their meetings, at which some of the most celebrated philosophers of France and of Germany and of other countries were present. Its reception was in the highest degree flattering, and the interest which they manifested, by the questions they asked and the exclamations they used, showed to me then that the invention had obtained their favorable regard. The papers of Paris immediately announced the Telegraph in the most favorable terms, and it has literally been the topic of the day ever since. The Baron Humboldt, the celebrated traveller, a member of the Institute and who saw its operation before that body, told Mr. Wheaton, our Minister to Prussia, that my Telegraph was the best of all the plans that had been devised.
