FOUND GROWING IN LIVING ANIMALS. 289 



I think it more probable, as previously expressed, that the animalcules al- 

 luded to by STILLING are infusoria rather than ascarides from the intestines. 1 



Birds OWEN,* on dissecting a flamingo, observed a green vegetable mould 

 or mucor, growing on the lining membrane of tubercular cavities in the lungs, and 

 on that of the smaller ramifications of the bronchial tubes. Thus, he remarks, 

 Entophyta exist in animals as well as Entozoa. 



EUDES DESLONGCHAMPS 3 noticed a similar appearance growing in an albumi- 

 nous layer, which was effused on the membranous lining of the air-passages in an 

 eider-duck. Examined with the microscope, it was found to consist of transparent 

 inarticulate filaments, slightly or not at all ramified, forming an inextricable felt. 

 There everywhere existed throughout this felted mass, a great number of small 

 globular or ovoid vesicles, which were undoubtedly the sporules. Some of the 

 filaments which were isolated were observed to support sporules with a capitu- 

 lum, whilst others terminated in a flat margined disk, which appeared to be the 

 mode in which those filaments terminated which had lost their sporules. 



A vegetable mould has also been observed by ROUSSEAU and SERRURIER,* growing 

 on a species of false membrane, effused between the intestines and vertebral 

 column of a male parroquet. Its adhesion was so feeble, that on blowing upon it, 

 it disappeared like the finest and lightest powder. They remark that pigeons 

 (more particularly the hens) are very liable to be affected, if these animals inhabit 

 cold and moist places, and in epochs of the rainy season. 



Mammalia. SERRURIER and ROUSSEAU merely mention having seen a vege- 

 table mould in a hind (Cervus Axis), but its nature, or on what part of the ani- 

 mal it grew, is not stated. With this exception, and that of the mouse alluded 

 to, p. 282 of this memoir, parasitic vegetations amongst the mammalia have hi- 

 therto only been found growing in man. 



SCHONLEIN of Berlin 5 was the first to recognise and figure a vegetable struc- 

 ture in the crusts formed on the scalp, in the disease named Porrigo lupinosa, by 

 BATEMAN. REMAK,* however, has claimed the priority of this discovery. 



1 CARUS has figured and given a description of conferva; growing on a dead salamander. (Nova 

 Acta, vol. ii. p. 493.) I may here observe, that similar conferva; may be produced at will, by allowing 

 frogs or gold fish to remain, after death, some time in water without changing it. In a few days they 

 become covered with a white efflorescence, which, examined microscopically, is found to consist of long 

 transparent tubes, jointed at regular intervals. I have frequently examined confervse thus produced : 

 they are different from those which grow on these animals during life.
