These are preparations of Bacteriological Culture media in a highly concentrated powdered 

 form, originated by Mr. F. R. Chopping, Assistant in the Clinical Laboratories at the Westminster 

 Hospital and exhibited at the meeting of the Royal Microscopical Society on April aoth, 1910 (see 

 reports). They are prepared for us under his supervision, are of small bulk, and do not deteriorate. 

 The method of using the media, which is extremely simple, is as follows : 5 c.c. of water are to be 

 added to a given weight of Solmedium in a test tube, the test tube is then placed in a water bath 

 for 30-45 minutes, and afterwards allowed to set in the required position. If a number of tubes 

 are required the Solmedium can be placed in a flask or beaker, the requisite amount of water added, 

 and the whole placed in a water bath until the Solmedium is dissolved, it is then tubed, the test 

 tubes placed in the water bath for 30-45 minutes, and afterwards allowed to set in the required 

 position (i.e. sloped or for stab cultures). Thus tubes of sterile media are easily and quickly 

 prepared. 



The following Solmedia are made and have been found to be quite satisfactory : 



SOLMEDIA AGAR-AGAR 



Glycerine Agar, and Glucose Agar are readily made from Solmedia Agar-Agar by 

 dissolving in 5% Glycerine solution or 2% Glucose solution instead of water. 



SOLMEDIA DRIGALSKI-CONRADI, 



SOLMEDIA SABOURAUD'S MEDIA, 



SOLMEDIA PEPTONE BROTH, 



SOLMEDIA BILE SALT AGAR (McConkey). 



It will be readily seen that many modifications may be made (for experimental purposes, etc.) 

 by using various solutions instead of plain water. 



Solmedia is supplied in tubes containing sufficient for 12, 50, or 100 5 c.c. tubes, with 

 directions for use.
