me-nt of hydrothorax and in peritonitis to prevent ascites. In 

 catarrhal diseases it lessens the discharge; in cerebrospinal menin- 

 gitis and muscular spasms to lessen the nervous irritability; to 

 check premature labor pain and prevent straining in eversion of 

 the rectum or uterus. 



Give the actions and the uses of ergot. 



Ergot is a powerful vasomotor stimulant, haemostatic, gastro- 

 intestinal irritant, and ecbolie. It stimulates and contracts invohin- 

 tary muscular fibres, and hence diminishes the blood-stream passing 

 through the arterioles ; large doses or small repeated doses produce 

 ergotism, which is characterized by gangrene of the extremities, 

 due to lack of blood supply to the parts. 



Ergot is used as an ecbolie to stimulate weak uterine contractions 

 and promote expulsion of the fcetus or foetal membranes; also used 

 as a vasomotor constrictor in postpartum or other internal 

 hemorrhage. 



Give the actions and the uses of the iron salts. 



Iron in general is a hsematinic, stomachic, styptic, astringent, 

 and haemostatic. The sulphate is a vermicide. The iodide is altera- 

 tive and resolvent as well as tonic. 



Iron is used in angemia, diarrhcea, intestinal worms, and as a 

 valuable tonic in convalescence from debilitating diseases. Locally, 

 the chloride of iron is used to check hemorrhage and as an astringent 

 in chronic pharyngitis and laryngitis. Internally, it is used as a 

 diuretic and tonic in purpura hemorrhagica. 



The hydrated sesquioxide of iron is a specific antidote for 

 arsenical poisoning. The phosphate is serviceable in diseases of bone 

 (rachitis, osteoporosis) and nervous exhaustion. The sulphate 

 improves the appetite and abates exhausting discharges in chronic 

 catarrhal rhinitis and endometritis. 



Give the actions and the uses of cantharides. 



Externally, cantharides is irritant, rubefacient, vesicant. In- 

 ternally, it is irritant, and stimulates the genito-urinary tract, 

 diuretic and aphrodisiac. 



It is used internally (rarely) to produce sexual excitement; 

 and for incontinence of the urine from paralysis of the bladder. 

 Externally, it is a valuable counterirritant and vesicant. Used in 

 sprains, tendovaginitis, periostitis, exostoses, wind-puffs, chronic 

 laryngitis and pharyngitis, and to stimulate the growth of horn 

 and hair.
