246 DISEASES OF CATTLE. 



from the navel into the abdomen, may be identified. The nave 

 enlargement may be considerable, but it is solid, does not gurgle 01 

 handling, and can not be done away with by pressing it back into th( 

 abdomen, as in a case of hernia. 



In cases at first closed the pus may burst out later, coming from th( 

 back part of the navel and the swelling extending backward. Ir 

 other cases whitish pus may pass with the urine by the ordinary chan 

 nel, showing that it has opened back into the bladder. In other case; 

 the umbilical veins become involved, in which case the swelling 

 extends forward as well as backward. Thus the disease may result ii 

 destructive disorders of the liver, lungs, and, above all, of the joints 



The disease may usually be warded off or rendered simple and com 

 paratively harmless by applying antiseptics to the navel string a' 

 birth (carbolic acid 1 part, water and glycerin 5 parts each, or wooc 

 tar). Later, antiseptics may be freely used (hyposulphite of soda < 

 drams, water 1 quart) as an application to the surface and as ai 

 injection into the urachus, or even into the bladder if the two stil 

 communicate. If they no longer communicate, a stronger injecbioi 

 may be used (tincture of perchlorid of iron 60 drops, alcohol 1 ounce) 

 Several weeks will be required for complete recovery. 



ABSCESS OF THE NAVEL. 



As the result of irritation at calving or by the withered cord, or b; 

 licking with the rough tongue of the cow, inflammation may attacl 

 the loose connective tissue of the navel to the exclusion of the urachu 

 and veins, and go on to the formation of matter. In this case a fira 

 swelling appears as large as the fist, which softens in the center am 

 may finally burst and discharge. The opening, however, is usuall; 

 small and may close premafurely, so that abscess -after abscess i 

 formed. It is distinguished from hernia by the fact that it can no 

 be returned into the abdomen, and from inflammations of the vein 

 and urachus by the absence of swellings forward and backward aloni 

 the lines of these canals. 



Treatment. — Treatment consists in an early opening of the absces 

 by a free incision and the injection twice a day of an astringent anti 

 <-3QPfcie (chlorid of zinc one-half dram, water 1 pint). 



INFLAMMATION OF THE NAVEL VEINS (UMBILICAL PHLEBITIS). 



In this affection of the navel the inflammation may start directl 

 from mechanical injury, as in either of the two forms just described 

 but on this are inoculated infective microbes, derived from a retaine 

 and putrefying afterbirth, an abortion, a metritis, a fetid discharg 

 from the womb, an unhealthy open sore, a case of erysipelas, froi 

 overcrowding, from filthy floor or bedding, or from an offensiv 

 accumulation of manure, solid or liquid. As the microbes vary i 

 different cases, given outbreaks will differ materially in their nature
