=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 with 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 actinomycotic 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 indicative of repeated obstruction in the pharyngeal, œsophageal or laryngeal region. At the moment of deglutition, the polypus is thrust towards and obstructs the œsophageal orifice. Reflex stimuli are thus excited, which prevent deglutition; an attack of coughing occurs, and food mixed with saliva is ejected from the mouth and nostrils. The attack of coughing displaces the polypus either in a forward or lateral direction, and swallowing then again becomes possible, until by changing its position the growth produces fresh signs of obstruction. In other cases the polypus may only be of such small size as to impede the food passing through the pharynx on its way into the œsophagus or to cause difficulty in respiration by partially blocking the pharyngeal portion of the nasal cavities. In such cases deglutition is only checked and rendered slower. Or again, the pedicle of the polypus may be sufficiently long to allow the growth at certain moments to fall in front of the laryngeal opening. Respiration is then painful, difficult and noisy. Unless the growth is displaced during the subsequent attack of coughing, asphyxia may appear imminent, or may even occur unless assistance is afforded. Guided by these symptoms, the operator will explore the pharynx manually, and thus discover the position and size of the tumour. Tumours of the naso-pharynx produce very similar symptoms. =The prognosis= is based on the information obtained by manually exploring the pharynx. It is relatively favourable if the polypus has a well-marked neck, but is very grave if the tumour is largely sessile and cannot be removed.
