Chap. L. Of Tumors^ Iwpollhutnes,^c. isr 



when any part happens to be hurt or weakened by external 

 Accidents, whence being unable to make an equal Refin- 

 ance with the relt of the Body, it will at length receive 

 fuch a Quantity of Fluid as will raife it into a Tumor. 



The Writers of Surgery, in all Ages, carefully following 

 one anothers Steps, have reduc'd all Tumors to four gene- 

 ral Kinds, viz, into the Natural Encyjled^ Critical^ and 

 Malignant ; and under thefe they have rank'd all the other 

 Species. But this Divifion is neither in iifelf very accurate, 

 nor rightly fuited to our Purpofe, as our Bufinefs is with 

 Horfes, we fliall therefore reduce them to the j^ Tumors re- 

 Natural and Encyfled only. Of the firll ducible to thg 

 Kind are all Boils and inflam'd Swellings; Natural and 

 and, in (hort, whatever Tumors are form'd Encyfled. 

 originally by the Fluids diftending their pro- 

 per Veilels, whether they be critical or malignant, for thefe 

 differ only in Degree from other natural Tumors. And of 

 the fecond are all thofe that are form'd within membranous 

 Cyjis or Bags, as TVenSy Jnburies, and fome Sort of Figi^ 

 and other Excrefcences that grow on the external Parts of 

 the Bodies of Horfes : And this agrees the beft with what 

 thefe Authors here obferved with refpedt to the Formation 

 of all Tumors by Fluxion and Congejlion, 



Thofe Tumors that are large, and come Abfcejfes cni 

 to Suppuration, and have Matter gather'd Impoflhumes. 

 within them, whether they be Natural or Encyfled^ are 

 termM Impojlhumes ; and when the Matter is lodg'd within 

 the common, but chiefly the larger Interftices of the Body, 

 as thofe Furrows or vacant Spaces between the Mufcles, or 

 between the Mufcles and Bones, they are then called Ab- 

 fcejfes ; but all Abfcelles, and moft kinds of Impofthumes, 

 are form'd of natural Tumors.

Fir/i^ When a Tumor happens to be fituated upon any 



Parts where there is no depth of Flefh, as on the Nofe and 



upper part of the Face, it will not be apt to grow large ; or 



If It be featcd upon the Skin or fiefhy Panniclc, and fiee from
