je 2 DISEASES OF THE DOMESTIC ANIMALS 



coronets of the affected feet. If lameness is persistent, neurectomy 

 may be indicated. 



In cattle, the general treatment — and that applied to the feet 

 — is similar to that for the horse. A pound or two of Glauber's 

 salts should be given at the onset, instead of oil. If separation of 

 the claw occurs, the foot must be dressed with a thick pad of tow 

 and Peruvian balsam and later tar. Chronic lameness would lead 

 one to recommend slaughter of the animal. 



Laryngitis (Acute, Chronic and Membranous). — Edema of the 

 Glottis. 



Acute Laryngitis. — Occurs in all animals, but chiefly in 

 dogs and horses. Caused by exposure to cold, irritants, infection 

 and spread of catarrh from nose and pharynx. Occasionally ap- 

 pears epizootically in horses. 



Symptoms. — Fever, dry cough, brought on instantly by pres- 

 sure on larynx. Noisy, difficult breathing in bad cases. These are 

 the chief symptoms, with absence of trouble in other parts of the 

 respiratory tract, and rales heard on auscultating the larynx. 



Treatment. — The animal should be kept quiet in well ventilated 

 surroundings. Local treatment is useful, as the application of cold, 

 moist compresses to the throat, covered with oil silk, or the use of 

 a thick coating of antiphlogistine ; or turpentine and sweet oil, equal 

 parts, and bandaging; or, in severe cases, a mustard paste or can- 

 tharidal blister. In addition, steaming with antiseptic solutions, as 

 two per cent, carbolic acid solution, is beneficial. 



Internally, a mixture containing tine, of aconite (3i for horses; 

 Tt\, v-x for dogs), and spiritus aetheris nitrosi (§i horses; 1TJ, xx 

 dogs) may be given three times daily, for fever. Laryngeal spasm 

 and cough are relieved by opium, e. g., morphine, gr. i for horses ; 

 codeine sulphate, gr. ss for dogs ; given thrice daily. If cough con- 

 tinues the following prescription is useful for dogs: 3J Ammon.
