TECHNIC 



From 2 to 4 centimeters of the vagus and posterior tibial 

 nerves are laid on a strip of cardboard and treated as follows : 



1. Harden in equal parts of Miiller's fluid and formaldehyde (10 per cent) 



for tv/enty-four hours. 



2. Replace by Miiller's fluid and keep in it for fifteen days. 



3. Wash in running v^rater for from tw^elve to twenty-four hours. 



4. Transfer the tissue for fifteen days to the follow^ing solution: 



cc. 

 Miiller's fluid 2 



2 per cent osmic acid solution 0.5 



Distilled w^ater 0.5 



5. Wash in running v/ater for from twelve to twenty-four hours. 



6. Dehydrate in graded alcohols, changing the absolute alcohol twice. 



7. Clear in oil of origanum, tease under a dissecting microscope, and mount 



in chloroform balsam. 



It is not necessary to place the nerves from one case in sepa- 

 rate bottles and label accordingly, because the posterior tibial is 

 always two to three times larger than the vagus nerve.
