The figures on the title=pages represent the Theatrum Anatomicum 

 of Copenhagen at Steno's time. They are reproduced from Thomae Bar* 

 tholini Cista Medica Hafhiensis. Hafhix 1662. 



In cases where the Treatise has been edited more than once, the editor 

 has made use of the text of the original edition. Differences between the 

 text of the original and that of the later editions have been mentioned in 

 the notes, except in cases where they are of no interest whatsoever. Only 

 in Treatise II the text of the second, considerably enlarged, edition has been 

 preferred, which edition appeared as early as one year after the publi= 

 cation of the first edition and was undertaken by Steno himself. Here, too, 

 the notes call attention to all variations of interest between the two editions. 



By far the greater part of Steno's works are written in Latin. In all of 

 these a uniform orthography has been carried through, corresponding as 

 nearly as possible to the orthography of the first works o/Steno, published 

 in Holland in 1 661—62, with the one exception, however, that the extensive, 

 but inconsequent use of accents has been abandoned. Unquestionable mis= 

 prints have simply been corrected, while in cases, where there is any un= 

 certainty whatsoever as to the justice of the corrections made, the original 

 reading has been given in the notes. This also applies to the Treatises 

 which are written in French, Italian and English, but in the latter only 

 mere misprints have been corrected, the orthography being otherwise 

 exactly reproduced. In quotations from other writers Steno makes use of 

 his own orthography; where there is any important difference between 

 the quotations, as found in Steno, and the same passage in the writer 

 quoted, these differences have been mentioned in the notes, whenever the 

 works in question have been within the reach of the editor. 



In the extracts from the MS. o/Jacobaeus the same orthography has 

 been carried through as in the text of Steno. 



Here as well as everywhere in the text of Steno the abbreviations have 

 been expanded, partly to make the understanding easier, partly for typo= 

 graphical reasons. 



The figures have been executed from photographs after the figures of 

 the original editions, except a few of the figures in Treatise XXII, which 

 unhappily have been reproduced by tracing the figures. The great plate 

 in vol. II facing p. 238 and the figures in the MS. of Jacobaeus have been 

 executed from photographs of the original drawings. With a very few 

 exceptions, of which account has been rendered in the notes, they have 

 all been reproduced in the size of the original.
