166 SYMPTOMS OF GLANDERS. 



under, the atmosphere he is breathing, tlie exercise he is taking, 

 &c. Bloody discharges, or rather blood tingeing the discharges, 

 will, in the latter stages in particular, every now and then become 

 apparent ; when present, they augur either deep or extensive 

 ulceration, or a disposition to ecchymosis, either from laxity of 

 fibre, or some change in the condition of the blood; and their 

 appearance is always inauspicious, though I never, myself, saw 

 blood lost to any but trifling amount. 



An Analysis of the Nasal Discharges has been made 

 by Lassaigne. He finds them to consist of albumen, mucus, 

 sub' carbonate of soda, chloruret of sodium, calcareous phosphate 

 (trifling in quantity), and water ; the water making the largest 

 proportion. In the normal state, the secretion of the Schneide- 

 rian membrane contains the same matters, with the exception of 

 the albumen, whose presence, in large proportion, keeps pretty 

 nearly pace with the quantity of purulent matter. From this it 

 would appear that the gluey or glutinous discharges owe their ad- 

 hesive properties to the predominance of albumen in their com- 

 position : they may, the same as purulent matter, issue out of the 

 follicles of the membrane ; though, in any considerable quantity, 

 I believe they may invariably be regarded as the product of ulcer- 

 ation. 



VASCULAR INJECTION or INFLAMMATION is ob- 

 servable in all acute and in certain stages of sub-acute cases, 

 upon the surface of the Schneiderian membrane ; though it is un- 

 common to see any intense degree of inflammation. This mem- 

 brane, which in health and under repose of body is of a pale flesh- 

 colour, under exercise of a vermilion hue, in a state of disease 

 often displays patchy blushes upon its septal surface, having a 

 peculiar shiny aspect, produced by the slimy or glairy secretion 

 coating the surface ; and we can generally perceive red vessels in 

 places traversing its substance. Now and then, from the dis- 

 charges adhering to it, the surface will present a patchiness of 

 yellow intermingled with the shiny red. Should all signs of vas- 

 cular action pass a\vay, the disease, from an acute or a sub-acute 

 running into a chronic form, the surface of the membrane will
