The manuscripts of Linnæus were no less freely consulted; but great was our disappointment to find the _Lachesis Lapponica_ written in Swedish. For a long time therefore it remained unexplored. At length Mr. Charles Troilius, a young gentleman in the mercantile line, resident in London, undertook the task of translating it. The manuscript proved to be the identical journal written on the spot during the tour, which certainly rendered it the more interesting; but the difficulty of decyphering it proved from that very circumstance unexpectedly great. The bulk of the composition is Swedish, but so intermixed with Latin, even in half sentences, that the translator, not being much acquainted with this language, found it necessary to leave frequent blanks, giving a literal version only of what he was able to read. The whole abounds also with frequent cyphers and abbreviations, sometimes referring to the publications or opinions of the day, and intended as memorandums for subsequent consideration. It is, in short, such a journal as a man would write for his own use, without the slightest thought of its ever being seen by any other person. The composition is entirely artless and unaffected, giving a most amiable idea of the writer's mind and temper; and it cannot but be considered as highly curious, to contemplate in these pages the development of such a mind as that of Linnæus. As not a word throughout the whole was written for the use of any person but the author, the reader may perhaps be disappointed at not meeting with any thing like a professed description of Lapland, or even a regular detail of the route of the traveller. What was familiar to Linnæus, either in books or in his own mind, is omitted. By the brilliant sketches he has left us in his _Flora Lapponica_, published a few years after his return, we see what he might have written had he here undertaken to communicate his own knowledge or remarks to others; and the same may be said of such of his dissertations, in the _Amœnitates Academicæ_, as professedly treat of subjects belonging to Lapland. The curious and learned reader will, however, here and there, meet with the first traces of ideas, opinions or discoveries, which scarcely acquired a shape, even in the mind of the writer, till some time afterwards. If on the one hand the Journal may seem defective in communicating information, the occasional quotations, references and allusions, the familiar and sufficiently correct use of the Latin language, and the general accuracy of the whole, give a very high idea of the author's accomplishments. The extemporaneous journals of the most illustrious travellers, made without a single book to refer to, or a companion to consult, would few of them perhaps stand the test of criticism so well.
