give you about the censorship of the press at Vienna, but have not energy enough left to write this evening. Thursday evening.--Nothing can be printed and published here, without first being examined and approved by a censor of the press. The government appoints four or five persons in Vienna, who examine in different departments, one for newspapers, one for works of science! others for different branches of literature. Every author must send his manuscript to the police-office, whence it is handed over to the proper censor, who certifies that it contains nothing immoral, nothing against the government, and that it is good literature, or science, or poetry, as the case may be, and worthy of being published; it is then returned to the author, with permission to print it. The author’s annoyance does not end here. He is obliged to leave a copy of his manuscript with the police, and a copy of the work as soon as printed, so that they may be compared, and any alterations or additions detected. If he desires to make any alterations in his manuscript after it has passed the censorship, he must send it back for a second examination. Persons holding responsible official situations are not exempt: if a censor himself wishes to publish anything, his manuscript must be given to the police that it may be examined by some other censor. All kinds of works, books of dry science not excepted, are subject to the censorship. To my great surprise, Endlicher, who gave me all this information, informed me that all the manuscript of his “Genera Plantarum” is sent to the police, who transmit it to Baron Jacquin, the censor for natural history, etc., and who is well paid for the business, but who knows just as much about it as if it were written in Arabic, and who certifies to each portion that it contains nothing hurtful to the people, nothing offensive to the emperor, to religion, etc., and more than all, that it is good science! To avoid the annoyance of sending it back repeatedly, as he has alterations to make, he is obliged to promise the printer to indemnify him, in case any discrepancy is observed between the manuscript and the printed work. Endlicher spoke of all this in terms which there is no necessity for me to record just at present. He gave me an anecdote respecting the publication of his earliest botanical work of any consequence, a Flora of his native town, the “Flora Posoniensis:” the manuscript being duly sent to Jacquin, that worthy refused to give it his imprimatur, because, it was arranged according to the natural system! which Jacquin did not like; and Endlicher was obliged to apply personally to the ministers and take great pains, when he obtained permission to print in spite of the censor; he took his revenge by dedicating the work to Baron Jacquin himself! This system sufficiently explains the low state of literature in Austria, as compared with northern Germany. I could hardly believe
