236 VEGETABLE PARASITES. 



A similar process occurred afterwards in the vagina, forming a 

 membranous layer on the mucous membrane of the vagina, which 

 was thrown off in single pieces. A slight improvement was 

 noticed. Prosector Dr. F. A. Zenker recognised in these masses 

 scanty pavement-epithelium, aJhd entangled fungous filaments 

 and spores, which were entirely surrounded by mucus-corpuscles. 

 Dr. Zenker was kind enough to send me some of these broken 

 pieces, and I obtained on addition of strong vinegar the partly arti- 

 culated filaments of which I have given an illustration on Tab. V, 

 in fig. 8. In order better to recognise the shape and articulations 

 of the very diaphanous filaments, I added Syrupus Rubi Idai, which 

 fully answered its purpose, and which I would recommend for 

 the purpose of examining vegetable parasites by means of acetic 

 acid. I use, however, a red ink when I employ potassa, since 

 the Syrupus Rubi Idcei would change its colour in alkalies. 



The above parasites remind us of those which Hannover found 

 on the ulcerated mucous membrane of the oesophagus, and in 

 cases of typhus. They very much resemble Leptomitus Hannoveri 

 (Tab. I, fig. 8), and ought accordingly to be classified with the 

 algae of Robin. 



This parasite resembles slightly the fungus given in Tab. V, 

 fig. 2, which Bennett found in the lungs. It appears to me, 

 however, that we have in fact to deal with a Leptomitus. 



EXPERIMENTS 



Made in order to test the parasiticidal effect of the most urgently 

 recommended remedies. 



I could not succeed in generating a continuous growth of 

 mucedinous fungi in mixtures of albumen and blood and water, 

 even after adding sugar, nor on Ascarides lumbricoides which 

 had been left to putrefy, and I resorted therefore to the mould 

 of very black bread, which I succeeded in keeping in a good 

 thriving state for weeks. 



Chance pointed out to me a pretty large piece of the so-called 

 pumper-nickel-bread, which I had bought warm at Cologne, and 

 which had been very much squeezed on the journey, so as to 

 render it highly humid and sticky, promising, a priori, on account 

 of the slight porosity of its interior, to keep for some time in 

 that moist state, and which is so favorable to the growth of 

 fungi. After this bread had become covered with dense mouldy
