I perceive that the Berlin Gazette is humanely occupied in recommending others to profit by the mistakes regarding contagion which occurred in that country:--"Dr. Sacks, in No. 38 of his Cholera Journal, published here, has again shewn, against Dr. Rush, the fallibility of the doctrine of contagion, as well as the mischievous impracticability of the attempts founded on it to arrest the progress of the disorder by cutting off the communications. It is to be hoped that the alarm so methodically excited by scientific and magisterial authority in the countries to the west of us [!!] will cease, after the ample experience which we have dearly purchased (with some popular tumults), and that the system of incommunication will be at once done away with by all enlightened governments, after what has passed among us."--I am sure, good people, nobody can yet say whether those calling themselves scientific, will allow us to profit by your sad experience; but I believe that the people of Sunderland are not to be shut in, but allowed to remove, if they choose, in spite of silly speculations. It may not be uninteresting to mention here, that there are no quarantines and no choleras in Bohemia or Hanover. LETTER IX. The following statement from the Duke de Mortemar will be considered probably, very curious, considering that, as already stated, he seems to believe in something like contagion--and for no earthly reason, one may suppose, than from his inability to satisfy himself of the existence of another cause--as if it were not sufficient to prove that in reality the moon _is not_ made of green cheese, but one must prove _what it is_ made of! But, to the quotation--"The conviction now established, that intercourse with sick produces no increase of danger, should henceforth diminish the dread of this calamity (the cholera). It differs from the plague in this, that it does not, by its sole appearance, take away all hope of help, and destroy all the ties of family and affection. Henceforth those attacked will not be abandoned without aid and consolation; and separation or removal to hospital, the source of despair, will no longer increase the danger. The sick may in future be attended without fears for one's self, or for those with whom we live." How delightful is the simplicity of truth! Why, Sir, a morceau like this, and from an honourable man, let him call himself contagionist or what he may, is more precious at this moment than Persian turkois or Grecian gems. Make me an example, men say, of the culprits "who let the cholera morbus into Sunderland," concealed in "susceptible" articles!--yes, and that we may be on a level in other matters, destroy me some half dozen witches, too, as we were wont to do of yore. But let us have more tidings from Russia to comfort the country of our affections in the hour of her affliction, when so much craft and subtlety is on foot to scare her.
