ADDITIONAL MEDIA 



The media listed below have been rather extensively employed in the past for 

 general or special purposes. Other media have been developed which are con-

 For the present we will continue to carry these media in stock for those labora- 

 tories where they have been in routine use or where it is desired to continue their 

 use for comparative purposes.
