668 CONDITIONS AFFECTING THE DEATH OF FUNGI. 



practical interest to the surgeon. Gartner and Plagge 

 employed carbolic acid in the strength of 1 per cent., 

 2 per cent., and 3 per cent., and also 1 to 1,000 sub- 

 limate solution. The materials used for the research 

 were pure cultivations in meat infusion of the following 

 organisms : 1. Non-spore-bearing anthrax bacilli ; 2. 

 Glanders bacilli ; 3. Streptococci from a case of puer- 

 peral fever; 4. Pyogenic streptococci; 5. Erysipelas 

 cocci ; 6. Micrococcus tetragenus ; 7. The bacilli of 

 diphtheria ; 8. Staphylococcus albus ; 9. Staphylococcus 

 aureus; 10. The cocci of osteomyelitis; 11. Bacillus 

 prodigiosus ; 12. Bacillus of typhoid fever free from 

 spores ; 13. Micro-organisms from a case of spontaneous 

 meningitis. The cultivations were mixed with the dis- 

 infecting fluids for only a very short time as a rule 

 eight to sixty seconds and a small quantity was then 

 introduced into nutrient jelly or blood serum. It was 

 found that the sublimate solution killed all these 

 organisms even in eight seconds, with the single excep- 

 tion of the meningitis organisms, which were still living 

 after sixty seconds. The 3 per cent, carbolic acid killed 

 all the organisms without exception in eight seconds. 

 In the case of the 2 per cent, carbolic acid the osteomye- 

 litis and the meningitis bacteria required thirty to forty- 

 five seconds ; with the 1 per cent, carbolic acid rapid 

 disinfection was only obtained in the case of the anthrax 

 and glanders bacilli. 



As regards the disinfecting action of certain chemical 

 poisons a large number of experiments have been made 

 which we need not here refer to in detail, but the 

 following materials which are much employed may be 

 mentioned : 



Action of Sulphurous acid was formerly recommended as a 



acid. U good an d cheap means of disinfection for dwelling-rooms. 



20 grammes of roll sulphur were burned per cubic centi- 

 metre of space ; in order to render the burning of the 

 sulphur easier 100 ctm. of sulphur matches and 40 ctm. 

 of spirit were added to every kilo of sulphur. In 

 this way an amount of sulphurous acid was obtained 

 representing 1*4 per cent, in volume. The duration of
