clothing. It has been used especially in the treat- 

 ment of psoriasis. As it is very liable to be ab- 

 sorbed through the cutaneous structure and cause 

 symptoms of toxicity, it is preferable not to apply 

 the remedy to but limited spaces at a time. 



ICHTHYOL. Ammonium sulphichthyolate and so- 

 dium sulphichthyolate are both known, according to 

 Dr. Unna, under the name ichthyol. Their action is 

 precisely alike, the latter, owing to its density, being 

 dispensed when pills are prescribed, the former in 

 ointments. They are dark brown of a fetid odor, 

 soluble in alcohol and ether Employed internally 

 in doses of 5 to 20 drops against lupus, angina, 

 asthma, diabetes, etc.; externally in unguental form 

 in the proportion of I to 3 parts vaseline or I to 5 

 parts lanoline. 



IODOFORM BITUMINATE. This is a preparation of 

 iodoform recently introduced by Dr. Ehrmann of the 

 Vienna clinic. It occurs in brownish micaceous 

 scales, which can be readily powdered, oras abrown 

 powder, and is destitute of any iodoformic odor, 

 retaining but a slight odor of tar. It has been 

 employed chiefly and with gratifying results in the 

 treatment of indolent ulcers; it may be used in all 

 cases where iodoform is indicated. 



IODOL. A pale yellowish-brown powder, used as a 

 substitute for iodoform. It is insoluble in water, 

 but soluble in alcohol and fixed oils. Also given in- 

 ternally for same purposes as iodide of potassium is 

 given for, in doses of one or two grains, in pill 

 form. 



MERCURY CARBOLATE. This occurs in colorless 

 crystals, very slightly soluble in water and alcohol. 



It was introduced against syphilitic affections, 

 being claimed to be safer than other mercurials.
