presence of minute proportions of any of these Compounds. So- 

 dium selenate and potassium selenocyanate do not retard growth. 

 Neither selenium dioxid nor sodium selenite can be used as a differ- 

 ential test for aerobic or anaerobic organisms, since several of the 

 latter class effected reduction. There seems to be no specific rela- 

 tionship between selenium reduction and hydrogen sulfid produc- 

 tion, as Gloger^^ maintained in the case of tellurium Compounds, 

 since microörganisms, such as B. acidi lactici, B. diphtherice, B. 

 pseudodiphtherics, B. tuherculosis, that produce no hydrogen sulfid 

 or only traces, are also capable of reducing selenium dioxid or 

 sodium selenite.
