THE FAUNA AND FLORA OF OUR METALLIC MONEY. 337 



Mugor stolonifer, Eh i'h. It forms white growths on various 

 substances, especially on putrefying vegetable bodies. 



Gh/Etocladium, Fres. It is a parasite on Mucor stolanifer, Ehrh., 

 found on animal excreta. The fungus showed sexual spores (Conidia). 



There was only one of the Haplomycetes, a species of Tonda Pers. 

 Identification was impossible, as I observed only spores without myce- 

 liums. The torulas' form dust-like coats on various bodies, usually on 

 dead and sometimes on still living bodies. 



The animal kingdom offered only few representatives. 

 Amoeba tbrrigola Grbbf. — Diameter of the whole body 350 — 400 /*, 

 I found it dead in the state of encystation. 



There were some 2 or 3 species of infusorians, but for want of a 

 sufficient number of specimens, determination was impossible. 



Of rarer occurrence were red blood corpuscles, fat cells of adipose 

 tissue, small portions of the epidermis of human skin, pus cells and even 

 eggs of insects. 



Very frequent were starch-grains of different plants : 



Starch-grains of potato.— By them the light is reflected to differing 

 degrees. Their hilum is not the geometrical centre, but lies nearer to 

 one end. Length 60 — 100 /*. 



Starch-grains of wheat ; they are circular, their lamination regular, 

 their diameter 35 — 40 /* . 



Starch-grains of rice ; they are very small, polyhedral ; compound 

 grains of great beauty are met with. Diameter 6 — 7 ^ . 



Starch-grains of West Indian arrowroot. The lamination is less clear, 

 but more Uniform than in potato starch. A cleft in the form of a V 

 characterises the starch of arrowroot. 



Also white and black pepper was found. The only difference between 

 the two kinds of pepper is, that in the white there are no particles of 

 the exocarp and no parenchyma of the seed-vessel. 



Cinnamon-powder, which was observed, is distinguished by the fol- 

 lowing elements. Thin spindle-like bnst fibres, circa 50 ^ in length ; 

 thick-walled cells of the bast parenchyma, containing starch, slerenchyma 

 with or without starch, oil-glands, crystals of calGium-oxalate from the 

 cells of the medullary rays. 



The greatest part of all the m itter detected on money, and found, 

 as the. chief constitutent part of the sedimentary layer, was diist» 

 &iz. microscopic and ultramicroscopic bodies of inorganic origin. Of
