same may be said of massa liydrargjri. Either |)reparation 

 may be given dogs as a laxative in indigestion with vomiting 

 and diarrhoea ; or to foals and calves with intestinal indiges- 

 tion and diarrhoea, particularly if accompanied with jaundice. 

 The oleatum or unguentum hydrargyri are rubbed into the 

 skin to cause resolution of chronic inflammatory swellings, 

 and also to kill animal and vegetable parasites. As the 

 former action is due to absorption, large quantities will lead 

 to poisoning when applied over an extensive surface. We 

 can use other and safer remedies, as creolin, tar or sulphur 

 ointment, for parasiticides. It is to be remembered in this 

 connection that grease alone will kill lice and other parasites 

 on the skin. On account of their sorbefacient properties, 

 the oleate and blue ointment of mercury are applied over 

 chronically enlarged glands, swollen joints, and thickened 

 tendons. In view of their parasitic action, these preparations 

 are employed to kill the fungus of favus and ringworm, and 

 to destroy lice and the acari of mange, when inhabiting 

 circumscribed areas. Itching in skin diseases, as chronic 

 eczema and psoriasis, is relieved by either blue ointment or 

 the oleate of mercury. 



HYDRARGYRI OXIDUM RUBRUM, OR FLAVUM. 



The official ointments of the red and yellow mercuric 

 oxides are prescribed, as stimulant and antiseptic prepara- 

 tions, in chronic conjunctivitis, granular lids and scaly skin 

 diseases. They are also employed on indolent ulcers, 

 swollen glands and old granulating surfaces. When used on 

 mucous membranes, or raw surfaces, the official ointments 

 should be diluted with equal parts of lard. 



HYDRARGYRI CHLORIDUM CORROSIVUM. 



External. — Corrosive sublimate is of value mainly as an 

 antiseptic on the unbroken skin. It is germicide in solutions 

 containing 1 part to 500, or 1,000, of water. Applied to 

 mucous membranes, or raw surfaces, it is antiseptic in solu- 

 tions varying in strength from 1-10,000 to 1-1,000.
