PREVENTION, SYMPTOMS AND TREATMENT T q 5 



eggs may be removed with a fine tooth-comb after the application 

 of a parasiticide. The following agents are most successful: — 

 Kerosene, which may be used night and morning for two days and 

 then removed by soap and water. In dogs, the tincture of staph- 

 isagria or oil of anise in alcohol (i-io). }4 to i per cent, solution 

 of corrosive sublimate is also efficient in dogs, if the hair is dried 

 before the animals have a chance to lick off the application. Innum- 

 erable other remedies are advocated, as i to 5 per cent, decoctions 

 of tobacco, 5 per cent, creolin, lysol or carbolic acid solution, equal 

 parts, or benzine and sweet oil, blue ointment, stavesacre seeds and 

 soft or green soap, each 1 part ; water 40 parts, boiled twenty min-

General cleanliness with care of the skin and good feeding are 

 to a considerable extent preventive measures. 



Pericarditis, Acute. 



Acute pericarditis is not uncommon in cattle and goats from 

 the ingestion of sharp bodies (as needles, pins, nails, etc.), and may 

 be recognized by symptoms at first suggesting indigestion — as dul- 

 ness, loss of appetite and rumination and tympanites — and later 

 those characteristic of the disease proper. As the treatment is nil, 

 except slaughter for beef, this form will not be further discussed. 



In horses and dogs acute pericarditis is generally caused by 

 acute infections, as acute rheumatism, pneumonia, pleurisy, puer- 

 peral septicemia; by traumatism, as broken ribs, gunshot; and 

 also by extension of inflammation from the heart, lungs, and 

 pleura (endocarditis, pneumonia, empyema, pleuritis) ; rarely by 

 penetration of ingested foreign bodies. 



Symptoms. — The general symptoms include fever, dyspnea, 

 jugular pulsations, and rapid, irregular pulse, at first strong and 

 later weak. The local signs are tumultuous heart-beat and a to-and-

 often felt, over the centre of the cardiac area. Effusion follows
