 temporary teeth. Such have not much practical 

 importance. 



The Molars of the ox (fig. 39) differ from those of the 

 horse mainly in the fact that the three anterior ones are 

 small, as compared with the three posterior in each series. 

 The fangs are smaller and more subdivided. The tables 

 are less complex and more rough and irregular, with 

 jagged points, which often injure the insides of the cheeks 

 (and such lacerations acquire importance, since it has been 

 proved that they are the breach through which the bacteria 

 enter in many cases of anthrax). These teeth are loosened 

 by epitheliomatous or osteo-sarcomatous growths. They 

 may be affected by caries, and those other pathological 

 conditions which have been seen in the horse, but such 

 cases seem to be extremely rare. "We also seldom find 

 records of their displacements abnormally. Cattle also 

 do not seem to suffer from teething. Our researches have 

 disclosed a case where the sole of a boot became fixed 

 on the molar series of one side of the lower jaw, giving 

 rise to dysphagia (difficulty in feeding). And in ' Veteri-
