6. The disinfection of the umbilicus and cord should 



be completed by applying the following: 



Methyl alcohol 1 quart. 



Iodine 30 gTains. 



7. When the alcohol has evaporated the operation 

 will be completed by dressing the cord and umbilicus 

 wdth a thick layer of iodised collodion (1 per cent.)- As 

 soon as the collodion has dried the calf may be left with 

 its mother." 



In one outbreak of infectious dysentery in valves I 

 have had good results by employing the following dust 

 powder : 



Tannic acid . 3 ounces. 



Boric acid 3 ounces. 



Iodoform 4 drams. 



Salicylic acid ... 4 drams. 



Mix and apply to the ligated cord and umbilicus 

 (navel) immediately after birth and two or three times 

 per day during the first three days. This thoroughly 

 disinfects and also dries up the cord very quickly. It 

 can be applied with a dust blower or sifter. 



If calves are allowed to suckle a cow, it is always best 

 to wash the udder once or twice daily with a 1 or 2 per 

 cent, solution of creolin or lysol. Just before birth it 

 is wise to wash the vulva, anus, perineum and tail of the 

 cow with one the above disinfectants. 



Barns, lots and pens must be thoroughly cleaned and 

 disinfected. Change calves and cows from one cleaned 

 and disinfected place to another and keep well calves 

 entirely isolated from sick ones. Use plenty of lime, 

 whitewash, carbolic acid, creolin, lysol and other disin- 

 fectants on walls, floors, etc. Above all wash and scrub 

 often the walls and stalls. 



Curative Treatment is not very promising; hence the 

 great number of remedies herein suggested. 



It is usually best to begin the treatment with a pur- 

 gative in order to remove the fermenting and irritating 

 materials in the alimentary canal.
