In regard to your coming to London with Colonel Lawrence and his lady, should he be married in February next, I have this to say: Your passage at that season of the year would, unless by a happy accident, be stormy and disagreeable, though not dangerous. I have scarcely yet recovered from the effects of the voyage, and should you be as bad a sailor as myself, and have a rough passage, it might give your constitution a shock. The month of April would be a much more agreeable period to cross the Atlantic; and you would still arrive here in time for the most fashionable and longer part of the fashionable season. It is my duty to inform you that a general conviction prevails here, on the part of Lord Palmerston, the secretary of the interior, and the distinguished physicians, as well as among the intelligent people, that the cholera will be very bad in London and other parts of England during the latter part of the next summer and throughout the autumn. They are now making extensive preparations, and adopting extensive sanitary measures to render the mortality as small as possible. The London journals contain articles on the subject almost every day. Their reason for this conviction is,—that we have just had about as many cases of cholera during the past autumn, as there were during the autumn in a former year, preceding the season when it raged so extensively and violently. Now this question will be for your own consideration. I think it my duty to state the facts, and it will be for you to decide whether you will postpone your visit until the end of the next autumn for this reason, or at least until we shall see whether the gloomy anticipations here are likely to be realized. I still anticipate difficulty about my costume; but should this occur, it will probably continue throughout my mission. It is, therefore, no valid reason why you should postpone your visit. In that event you must be prepared to share my fate. So far as regards the consequences to myself, I do not care a button for them; but it would mortify me very much to see you treated differently from other ladies in your situation.
