If, on the other hand, an intending purchaser desires full particulars with 

 regard to the construction of instruments, the present more systematic arrange- 

 ment of the general part of the catalogue will enable him to find what he 

 requires with the least difficulty. In this case reference to the special list will 

 not be necessary, because prices and code-words are also appended to the separate 

 descriptions of instruments. 



With the exception of the price of the large Mineralogical Stand (Stand l b ), 

 which we have been able to reduce by Marks 50. , no material changes have 

 been made in the prices of articles. 



A selection of complete microscope outfits, adapted for a great variety of 

 purposes, will be found at the end of the catalogue.
