    OLEUM MORRHU^I. The internal use of cod-liver oil may cause an eruption ol a miliary or eczematous character. Duclos says that the eruptions of cod-liver oil are always vesicular, and spread over the entire body.1 Other observers, among whom h Farquharson, says that it causes an eruption of acne, presum- ably from the passage through the cutaneous glands of some of its acrid constituents. OLEUM RICINI. The only reference to the irritant effect of castor oil upor the skin which I have found is in Piffard's Materia MedicE and Therapeutics of the Skin. Langier is quoted to th( effect that pruritus and erythema have been caused by th( ingestion of the oil.2 OLEUM TIGLII. The application of croton oil to the skin causes more oi less irritation, according to the duration of contact and sen- sibility of the skin. Ordinarily, after a few hours redness appears, and a copious crop of papules which rapidly become converted into vesicles and then into pustules. The lesions may first develop as vesicles without passing through th( preliminary papular stage. The vesicles may be discrete oi confluentj sometimes bullae of irregular outline and of con- siderable size may form from their fusion. The contents oi the vesicles, at first transparent, soon become turbid anc purulent. The pustules are usually rounded or globular rarely flattened or umbilicated. At first they are tenselj distended, but soon wrinkled from partial resorption of the contained fluid. The walls of the bullae are easily ruptured disclosing a superficial excoriation which becomes covered 1 Lewin (quoted by Crocker) refers to these eczematous eruptions.— T. C. F. 2 OLEUM SANTALI. A general petechial eruption arising on the thirteenth day in a youn§ woman has been described. The eruption ceased when the drug was discon. tinued. In respect to eruptions attributed to this medicament possibh adulteration with copaiba must be considered.—T. C. F.
