Liquid carbolic acid or cresylic acid was a new substance in these 

 trials and a little variation in quantity was made. 



Creosote, saponified creosote, paraffin emulsion, and turpentine 

 emulsion, naphthalene, iodine, and copper sulphate were allocated 

 to other plots, whilst mercury bichloride was put in small quantities 

 on a more lightly infected place. 



This is all shown in Table VIII.
