PHARYNGEAL POLYPI. 143 



description at this point. No exact investigation of tlie organisms which 

 produce these forms of pharyngitis with false membrane formation has 

 been made in veterinary surgery. We only know that these diseases are 

 not true diphtheria due to " Klebs' bacillus." Treatment should be very 

 energetic from the commencement, but otherwise it differs in no respect 

 from that ordinarily adopted. 



Tonics and stimulants, like alcohol, wine, coffee, etc., are indicated. 



[The fohowing account of the disease is summarised from Law's 

 " Veterinary Medicine," Vol. II.] 



"Pseudo-membranous pharyngitis has long been recognised as a 

 contagious disease of swine, attacking especiahy swine kept in herds 

 or in close, insanitary pens. Young pigs are more hahle to attack than 

 older animals, perhaps, owing to the older animals having suffered the 

 disease in early life. 



Modern observation shows that pharyngitis with false membranes 

 is common in swine plague, and the present tendency is to refer all 

 such cases to that category. It is, however, altogether probable that 

 the occurrence of local irritation, with the addition of an irritant or septic 

 microbe altogether distinct from that of swine plague or hog cholera, 

 gives rise at times to this exudative angina. Certain it is that septic 

 poisoning with the food is not at all uncommon in the hog, in the absence 

 of these infectious diseases. 



Symptoms are those of sore throat, with much prostration, a croaking 

 cough, yellow discharge from nose and mouth, and marked muscular 

 weakness. The tongue, tonsils and soft palate are red, swollen, and 

 studded with patches of false membrane. The identification of swine 

 plague may be made by the history of the outbreak, the number of 

 animals affected, the tendency to pulmonary inflammation, the enlarged 

 lymph glands, the presence of the non-motile bacillus, which does not 

 generate gas in saccharine media, and which readily kills rabbits and 

 pigs wdth pure cultures of the germ. 



Treatment. Isolation, cleansing and disinfection. Locally antiseptics 

 and generally a febrifuge regimen will be advisable." 



PHARYNGEAL POLYPI. 



The term "pharyngeal polypi" includes tumours of varying 

 character, which affect the polypus form, and occur with considerable 

 frequency in the bovine species. Many of these polypi are simply actino- 

 mycotic growths springing from the pillars of the fauces, from the 

 upper parts of the palate or from its posterior surface. Less frequently 

 they arise from the lateral walls or the free surface of the hard palate. 



Symptoms. The symptoms are so characteristic that the diagnosis 

 rarely presents much difficulty. They may shortly be described as
