224 VEGETABLE PARASITES. 



globules were seen in the cavities of the filaments, of O'OOl 2 X " 

 in size,, and longish spores in others. Bennett has since found 

 other indistinct vegetable formations, in a yellowish-green stool, 

 consisting of confervoid, entangled, elongated, articulated tubes, 

 with spores, and exhibiting a great inclination to break across. 

 (Bennett, On the presence of Confervse, &c., ' Monthly 

 Journal of Medical Sciences/ 1846, and ( Lectures on Clinical 

 Medicine/ Edinburgh, 1851, p. 215, figs. 83, 84.) 



Langenbeck describes similar formations in the pharynx down 

 to the cardia, in a case of typhus. 



Robin is of opinion that the latter fungus is Oidium albicans. 

 (' Repertorium fiir Anatomic und Physiologic/ von Valentin, 

 1840, v, p. 45. 



Remak (1845) found several kinds of fungi on aphthae. He 

 thinks that the generation of fungi is always preceded by soften- 

 ing and loosening of the mucous membrane. He also believes 

 that he has discovered ramified thallus-threads on the pseudo- 

 membrane of a croupous patient. (Remak, ' Diagnost. und 

 pathogen. Untersuchungen/) 



It is to be regretted that these latter observations have all been 

 recorded too incorrectly to enable us to classify them. 



Reference has already been made to Wedl, Henle, Virchow, 

 Meissner, &c., as speaking of filamentous fungi which occur in 

 the mouth. I need not repeat what has already been said when 

 speaking of the Algse, according to Robin, and of LeptothiriM 

 buccalis. 



IX. Fungus of the Lungs (Bennett) = Champignon du poumon. 



Tab. V, fig. 2. 



The mycelium of this fungus is composed of long tubes, 

 provided with partition walls and unequal articulated intervals, 

 bearing several branches, which sometimes consist of one cell, 

 set into the stem at the end of the last cell, and parted in the 

 shape of a fork ; sometimes simply separated into two or three elon- 

 gations at their point of articulation. These branches are 0*005 

 O'OIO'" in diameter. The spores are numerous, and are 0-010 

 0'014 /x/ in diameter. Bennett saw these spores become longer 

 and form tubes. He found the fungus in the expectoration, in 

 the caverns, and in their tuberculous matter, in a case of pneumo- 

 thorax.
