PATHOLOGY OF PARTURITION. 



or tincture of camphor to them and into the wounds. It is often advisable 

 to trace a line around the gangrene, so as to circumscribe it. When it is 

 surrounded by a ring of inflammation, then emollient poultices may be 

 applied to hasten its separation ; indeed, if the part is quite dead, it may 

 be judicious to cut into and remove as much of it as can be done — cau- 

 terizing the wound well with the hot iron or perchloride of iron, and after- 

 wards dressing it with chloride of lime, carbolic acid, and other antiseptics. 

 At the same time, antiseptic medicines, tonics, and stimulants, should be 

 administered internally. It migl>t be well worth trying the injection of 

 antiseptic agents — such as carbolic acid, tincture of iodine, etc., into the 

 gangrenous tissues, by means of deep incisions and a Pravaz syringe. 



Induration following mastitis can rarely be remedied, but it may be 

 useful to continue the inunction of ointments which contain preparations 

 of mercury — as the iodide — or iodine for a certain time. Armatage 

 recommends the following ointment to be applied once a day, with smart 

 friction : 



Soft soap - }^ lb. 



Mercurial ointment - - - - i oz. 



Camphor ointment - - - - 4 " 



Extract of belladonna - - - 4 drams. 



Or the following tincture : 



Tincture of iodine - - - - 6 oz. 

 Tincture of opium - - - - 2 " 

 Soap liniment - - - - - 4 " 



Frequent and gentle milking may also prove serviceable, as well as dry 

 friction. 



As a preventive measure when infection is apprehended — as in reten- 

 tion of the placenta, metritis or vaginitis, etc. — it is advisable to inject a 

 weak solution of carbolic acid (2^ per cent.) or alum (2 per cent.), up 

 the teat by means of a glass syringe, always after milking ; the fluid 

 should be at a temperature of 95° Fahr. Franck has proved the value 

 of this precaution, and also its utility as a remedial measure ; indeed, 

 Armatage had previously recommended the injection of weak solutions 

 of carbonate of soda or potash in mastitis. Franck has employed a ten 

 per cent, emulsion of carbolic acid as an injection in artificially-produced 

 mastitis (sixty grammes daily), and by this means suppressed the develop- 

 ment of micrococci and bacteria in the milk, as well as prevented curd- 

 ling of that fluid in the ducts and sinuses. Solutions of alum — ten per 

 cent., 100 grammes injected daily — appeared to be also beneficial in this 

 direction. 



Armatage recommends that animals suffering from gangrene of the 

 mammae should be removed from those which are pregnant, " as great 

 excitement will be produced by the odor of decomposition," and abor- 

 tion is probable. 



CHAPTER X. 



Agalactia. 



" Agalactia," or absence of milk in the mammae, is not uncommon in 

 animals, particularly the Mare and Cow, and more especially in those
