ON THE PATHOLOGICAL MORPHOLOGY OF SOME ANIMAL FLUIDS 267 



adjacent intermediate vessels is interdicted ; hence metastatic inflam- 

 mation in organs, endowed with fibres, occurs very rarely. Among 

 these we number fibrous organs, as tendinous fibres, muscular fibre, 

 nervous fibre, compact neurilemma, and osseous fibre, also organs en- 

 dowed with an erectile tissue, as the glans and corpora cavernosa of 

 the penis, and clitoris, the papillae of the breast, and also the parietes of 

 the arteries. 



2nd. Moreover, hard glandular organs, as the prostate, virile, mamma, 

 testicles, ovaries, womb, liver, kidnies, thyroid gland, the parenchyma 

 of the spinal marrow and brain, the skin of the sole of the foot, of the 

 palm of the hand and of the back. The less the resistance offered by 

 the surrounding tissues to an intermediate vessel obstructed by a glo- 

 bule of pus, by so much the more difficult is the onward progress of 

 that globule rendered ; the greater the dilation the quicker and more 

 frequent does metastatic deposition occur. Here we number soft, sub- 

 cutaneous cellular tissue surrounding muscles, nerves, and salivary 

 glands ; the cellular tissue of the female breasts, orbit, &c. ; vascular 

 membranes, as that of the brain and spine, iris ; synovial organs of 

 the joints ; soft parenchymatous organs, as the lungs, spleen, mucous 

 membrane, and the skin, where it offers a soft, weak texture, as that 

 of the eyelids, ears, pudenda of women, &c. 



Pus received into the veins passes very rapidly by the pu Imonary 

 artery into the intermediate vessels of the lungs, where it chiefly pro- 

 duces metastatic lobular stagnations and inflammations. 



But pus in the arteries is carried around to those organs chiefly to 

 which the greater quantity of arterial blood is borne, or to which in the 

 normal state the excretion of heterogenous substances, mixed with the 

 blood, takes place, (brain and kidnies.) 



3rd. The organs whose intermediate vessels are endowed with a 

 large or too narrow diameter, seem unfit for metastatic depositions, 

 as, for example,* the intermediate vessels of the corposa cavernosa, 

 penis, are endowed with the largest diameters = yV^ 6 ^- of a Vienna 

 inch ; on the contrary, the smallest diameters of intermediate vessels 

 are found in the tendons = TorVoro ^ a Vienna inch. 



In the same manner as the stagnation of the blood precedes exuda- 

 tion and hepatization in lobular inflammation, so in every inflammation 

 of any substratum, of any extent, from whatever cause arising, the 

 local stagnation, or at least the impeded and retarded propulsion of the

 Berres.
