394 REPORT OF NATIONAL MUSEUM, 1890. 



veloped the whole of this class of prints, the latter nevertheless retain 

 their interest, historically as well as technically considered. A nd it may, 

 indeed, be claimed that the recognition of the true state of the case 

 has given them an added interest which did not attach to them before. 

 This interest flows from the perception of the close connection exist- 

 ing between these crude productions of past centuries and the highly 

 developed technique of our own day, a connection which up to the 

 present has escaped the notice of all observers.
