APPENDIX. 



As a matter of convenience to the student we present 

 the addresses of American dealers in Microscope Stands, 

 Objectives, etc. The list is compiled from the various 

 catalogues and other sources of information which hap- 

 pened to be in our possession. It is therefore probably 

 incomplete, but nevertheless will be found to comprise 

 most, if not all of the leading dealers. Of the latter, 

 those marked with an Asterisk (*) issue illustrated cat- 

 alogues, which can be obtained on application, free of 

 expense :
