hair has been shaved from the part. During an operation, 

 irrigation with corrosive (1-3000) solution or boiled normal 

 salt solution is commonly practised. In epizootic abortion, 

 in addition to quarantining the diseased animals, their dis- 

 charges and the premises should be disinfected, and both the 

 well and sick female animals should be washed twice daily 

 about the genital regions with a solution of corrosive subli- 

 mate. Yellow wash, made by the addition of 30 gr. of mer- 

 curic bichloride to 1 pint of lime water^ is sometimes em- 

 ployed as a stimulant application in chronic eczema, 'and to 

 relieve itching. It contains the yellow oxide of mercury. 

 In purulent conjunctivitis, frequent irrigation with a 1-1000' 

 solution of corrosive sublimate is of the greatest service. 



Internal. — Corrosive sublimate is of value in minute 

 doses as a blood tonic, and is recommended as an antiphlo- 

 gistic agent in inflammatory diseases of serous membranes, as 

 pleuritis, meningitis, and arthritis. It is probably inferior 

 to calomel for this J)urpose. "We at least know that calomel is" 

 an efficient cathartic in inflammatory diseases. 



Mercuric bichloride is employed as an intestinal anti- 

 septic in the treatment of dysentery and diarrhoea with mu- 

 cous or vile smelling discharges. In these conditions, irri- 

 gation of the rectum with a 1-5000 solution is of advantage. 

 This solution should be drained off through the rectal tube 

 and followed by an injection of plain boiled water. 



Administration.^Covrosiye sublimate is given in the 

 form of a pill or ball. If exhibited in solution to the large 

 animals, it must be diluted with 2 quarts of water.

External. — Calomel is of use in chronic eczema when 

 applied over small patches in its pure state, or as "black 

 wash." The latter consists of one drachm of calomel in one 

 pint of lime water, forming the black oxide of mercury, and 

 is a very efficient preparation to relieve itching and promote 

 recovery in chronic eczema, by mild stimulation. Calomel 

 is of benefit when blown into the eye once or twice a week, 

 stimulating and hastening absorption of opacities of the 

 cornea following keratitis. It is the best agent to arrest
