GERMICIDES AND ANTISEPTICS 329 



solution easily destroyed the sporeless bacilli, but 

 in a '5 per cent, solution they were not destroyed. 



As an antiseptic agent carbolic acid, in the shape 

 of dressings and lotions, and as a spray in surgical ( 

 operations, is of the greatest value ; but, according 

 to Jalan de la Croix, 1 its germicidal properties are 

 inferior to those of salicylic acid. 



Among the oxidising germicides and antiseptics 

 are the following : Hydrogen dioxide, ozone, ' sani- 

 tas oil,' 'sanitas fluid/ potassium permanganate 

 (Condy's fluid), and turpentine oil. All these sub- 

 stances have germicidal and antiseptic properties, 

 which are due (directly or indirectly) to the libera- 

 tion of nascent oxygen. 



The author has shown that when silk threads, 

 impregnated with tubercle bacilli and the bacilli of 

 hay fever, were placed in a mixture containing 5 cc. 

 of 'sanitas oil' and 100 cc. of water for seven days, 

 the microbes were completely destroyed by this 

 powerful oxidising agent. 



Mr. C. T. Kingzett, F.C.S., 2 has performed a 

 large number of experiments with ' sanitas oil ' and 

 ' sanitas fluid,' and his experiments prove the high 

 value of these preparations as germicidal and anti- 

 septic agents. 



In addition to the above-mentioned germicides 

 and antiseptics there are many others, among these 

 being the following : Sulphurous anhydride, alka- 

 line sulphides and hyposulphites, hydrogen sulphide
