thirty g/ains of iodide of potass in two lances of fluid extract of 

 resin-weed root; an occasional dose of golden seal was given as a 

 tonic. The iod?de of potass acted on the system as a glandular 

 stimulant, and thus increased the power of the absorbents and ex- 

 crement; t ; ous vessels, to rid the chest of its Sum! contents, while 

 the resin-root acted as a diuretic, thereby carrying off some of the 

 fluid by way of the kidneys. During the period of the sickness 

 o*" this animal, the resonance of the chest gradua^v became clear, 

 so that at the end of three weeks not more than a coaple of pints 

 of serum remained in the chest. The animal rapidly convalesced. 



During the treatment of such a case as the above, I usually feed 

 the animal liberally on oats and sweet hay ; and, in order to obvi- 

 ate constipation, I order an occasional bran-mash. The animal, 

 however, may not, at the commencement, have much relish for 

 food, but after a few doses of the medicine here recommended have 

 been given, the appetite will soon be restored. It will be noticed, 

 during the progress of this malady, that the animal does not lie 

 down, but stands with the fore-legs widely apart, although, at the 

 very commencement of acute pleurisy, the subject will often get 

 down, in view of mitigating the lancinating pain from which he 

 suffers, in consequence of the distension of the vessels of the pleura. 

 Pleurisy sometimes sets in as an accompaniment of influenza, 

 which almost always ends in dropsy of the chest ; and as a case ol 

 this kind is a good one to place on record, I here introduce one 

 from my note-book : 



Pleurisy ending in Dropsy and Death. — The horse, the subject 

 of the above-named maladies, was the property of a milkman of 

 Chicago. The animal had been previously treated for the prevail- 

 ing influenza, accompanied by pleurisy, and had about recovered 

 so as to take daily exercise ; but finally the owner discovered that 

 the horse was suddenly taken with a relapse. Feeling alarmed, 

 he procured one pint of linseed oil, with which he drenched the 

 animal. Still, the horse rapidly grew worse. At this period, my 

 services were sought. On auscultating and percussing the chest, 

 I found that the right cavity was occupied by a large quantity of 

 water. Dropsical swellings were found in various parts of the 

 body, viz. : the sheath, limbs, and region of the pectoral muscles. 

 On applying the ear to the trachea, the respiration was of a mucous 

 character, and tubular, showing that the lungs were much diseased. 

 The examination revealed the tact that about one-half the left ] ung
