324 INFLAMED LUNGS IN SHEEP. 



which half an ounce of the extract of gentian has been 

 rubbed down, and thus compose a drink. No ginger, 

 though that stimulant is justly a favourite, must be given, 

 for fear of recalling the inflammation, which we have too 

 much reason to dread has not been entirely subdued. The 

 food must not be too large in quantity, but of the most 

 digestible kind.

Horned cattle are also subject to pneumonia, but not by 

 any means in an equal degree with horses. Cowleeches 

 and graziers call the complaint rising of the lights, and it 

 has also other provincial names unnecessary to be noticed 

 here. Various causes may occasion it ; as exposure to in- 

 clement weather, over- driving from fairs, &c., in which the 

 vicissitudes of temperature they undergo, acting on their 

 plethoric state, distend the pulmonary tissues. We have 

 also seen it in calves. The symptoms are the same as in 

 the pneumonia of horses : we know of no difference, but 

 that the mouth is moistened by a discharge, and held con- 

 stantly open to assist the breathing. It must also be 

 observed, that the low type is apt to prevail in all their 

 diseases ; and that, from the increased volume of their 

 aortic system, their inflammations hurry to their termina- 

 tion, be it bad or good, sooner than those of the horse. 

 Hence it is more common for pneumonia to end in gan- 

 grene in cattle than in horses. The treatment differs in no 

 respect. It may also be remarked, that structural pecu- 

 liarity in the alimentary track makes it proper to give all 

 cattle medicines in a liquid form.

Few of the writers about cattle notice this disorder 

 as a disease affecting sheep ; but it may be seen well 

 marked, and in these animals also its origin could be clearly 

 traced to exposure to inclement weather. The first ap- 

 pearance is loss of appetite, which is soon succeeded by a 

 fixed stare ; the head is elevated in the air ; the mouth 

 opened ; the flanks heave violently ; the conjunctival and 

 nasal membranes are much injected, and a fluid distilled 

 from the nostrils, mucous in some, and purulent in others.
