SARCOMATOUS DISEASE OF THE LUNG. 515 



What was the nature of this disease, which continued for nearly 

 five months producing these painful crises ? Our diagnosis always 

 hesitated between rheumatism and pachymeningitis. I have seen 

 several other patients suffering from similar though less violent and 

 less persistent attacks, due to rheumatism. I incline to think that in 

 this dog a rheumatic localisation had occurred in the meninges and 

 auditory apparatus. The hypothesis of ossifying pachymeningitis is 

 scarcely compatible with the perfect and lasting recovery. 



SARCOMATOUS DISEASE OF THE LUNG. 



201. A fifteen-year-old entire horse, entered hospital June ist, 

 1897. For two years previously this horse had enjoyed good health. 

 The sides of the chest were marked by hairless patches due to long- 

 previous blistering. On the 25th May the animal experienced a chill 

 and showed some alarming symptoms, regarded as due to broncho- 

 pneumonia. 



State on Examination. — On the day of entering hospital the patieiit 

 exhibited evident signs of grave disease ; the mucous membranes were 

 injected and slightly swollen ; the respiration was very rapid (50 per 

 minute) ; cough readily followed pressure on the larynx, and was loud, 

 moist, and inclined to recur ; there was abundant mucous discharge, 

 which contained numerous organisms, among others an encapsuled 

 diplococcus, which stained by Gram's method. Nothing abnormal 

 was noted on percussing the chest. On auscultation the vesicular 

 murmur could be detected over the entire area of both pulmonary 

 lobes. The heart was normal, the pulse accelerated {yo per 

 minute). The appetite was good, the animal ate all its food ; the 

 faeces were normal. Temperature 40*8° C. The cough, discharge, 

 difficulty in respiration, and coloration of the mucous membranes 

 appeared to indicate that the animal was suffering from pneumonia, 

 still localised in the deep parts of one or both lungs. 



Treatment. — Sulphate of quinine, and sulphate and bicarbonate of 

 soda internally ; fumigations with menthol (produced by adding a 

 tablespoonful of the following mixture to half a bucket of hot water : 



Menthol .... 10 drachms. 

 Oil of turpentine . . 10 drachms. 

 Alcohol .... izh ounces.) 



From the 2nd to the 14th June little change occurred. The per- 

 sistence of fever, cough, and dyspnoea, and the signs furnished by aus- 

 cultation and percussion, led us to diagnose chronic pneumonia with 

 abscess formation in the lung, or tuberculosis. The fumigations were 

 stopped. Nothing abnormal was found on rectal examination. The 

 discharge contained no tubercle bacilli. The urine was highly charged 

 with deposit and was, slightly alkaline, but showed no epithelial casts, 

 or sugar, and very little albumen. The reaction for indican was 

 doubtful. 



On the 15th June the chest was punctured, with the hope of obtain- 

 ing a little pleural liquid for examination ; nothing escaped.
