on EXPECTORATED MATTER, 



tinuitj', or breach of surface of the bronchial merabraiie, 

 very commonly occurring in puhnonary consumptions. 



V. The in,atter which consists of opaque viscid masses, 

 together with transparent fluid ; or the second sort above 

 stated, with nodules of the third or fotirth kind. 



VI. Pus from tiie vomicae of tubercles. 



VII. Pus from vomicsc by simple inflammation of the 

 lungs, and without tubercles. 



Other Idnds. Other kinds of matter are occasionally Coughed up, such 

 as calculi. — masses of self-coagulated lymph — serous fluid 

 — blood itself — and perhaps the vascular substance of the 

 lungs; but I do not write on these matters, beeause they 

 either do not belong to any particular recognized disease, 

 or they are rare occurrences in some well known disease, 

 and are too obvious to require description. 



Sect. I. Sensible, or obvious Properties* 



Jellylite bine- !• The jellylike matter^ as already said, is excreted in the 

 ish matter. best health, as well as sometimes in disease. It is mostly 

 coughed, c^r hawked up, in a morning, soon after a night's 

 repose, during which it seems to accumulate. A few masses, 

 or nodules, then aj)pear of the consistence of jelly, and from 

 the size of a pea to a hazle nut. It is also at any time lia- 

 ble to be excreted, in consequence of various extraneous 

 matters irritating the fauces, to the amount of a few no- 

 dules. It is of a grayish colour, or inclining to blue, with 

 black specks; and it is rarely whitish in nodules. The con- 

 sistence is that of jelly, but of much greater tenacity. It 

 has a barely perceivable taste of coram on salt, or muriate 

 of soda. It commonly floats on water, but by agitation to 

 disengage air bubbles, it sinks. It has no smell. To the 

 naked eye, or assisted by a single magnifier, this matter 

 seldom appears uniform, but consists of a mixture of opaque 

 -and transparent masses of irregular figures. With the com- 

 . pound microscope, spherical particles were nerceive<l, though 

 few in number, when duly diluted. The presence of an 

 alkali I could in no instance perceive, by means of the usual 

 tests, namely, turmeric paper, litmus paper slightly red- 

 dened by vinegar, and cloth stainfd with violet juice ; nor 

 was an acid denoted by means of litmus paper, except whea 



I had.
