199. OBREGIA'S Method. Slides are prepared as directed ( 191), 

 the sections are arranged on them and covered with celloidin or 

 photoxylin and evaporated as described, 191. 



for DIMMER'S modification see also 191. 



200. Collodion Film Method.* GRAHAM KERR (in litt., 1908) 

 seriates on Kodak films. A film has the emulsion removed by hot 

 water. The sections are arranged on a dry film, and the application 

 of a drop of absolute alcohol and ether (or an atmosphere of alcohol 

 and ether) suffices to weld them into a mass with the film. The 

 sheet may then be stained and mounted, or rolled up and stored in 

 cedar oil. 



Other Methods for Celloidin Sections. See 193 (FoL) and 182 



(OLT). 



* The late Dr. S. G. Scott used mica sheets, upon which he stuck 

 paraffin sections. These could be distributed to a class of students by 

 simply cutting out pieces of mica supporting the sections.
