C. EL Fritts—New Form of Selenium Cell. 471 
sank rapidly to 22,000 ohms. The same experiment, with 
double cell No. 2, the mate to No. 1, produced ‘hardly any 
effect. When the “strip” cell was tried in the same way, it 
more strikingly by cells of my form than by those heretofore 
made. But why it occurs with some cells and not with others, 
has not been ascertained. - The sensitiveness to light is greater 
when the cell is cold. 
ew form of Selenium.—Since the foregoing paragraphs 
were written, I have been trying some experiments long con- 
templated, and have succeeded in producing colorless, trans- 
parent selenium. 
tis well known that vitreous selenium when very thin be- 
comes translucent and has a beautiful ruby red color. The 
new form of selenium just discovered by me has no color, but 
looks like a thin coating of glass, through which the yellow 
brass base is clearly seen,—even the fine scratches and marks 
left in the hrass from the polishing being as distinct as if the 
metal were bare. The mode of obtaining it is such as to 
one-half square inch of surface, had a resistance of only 
three ohms. It was found to be affected by light very little, 
if at all. 
As circumstances compel me, much against my will, to 
devote most of my time to a widely different branch of science, 
Ido not wish to stand in the way of those who would work 
out these subjects more rapidly, and therefore offer my results 
for their consideration, and Jeave further researches to be 
carried out by any desiring to do so who may have more 
time and better facilities than myself for theoretical inves- 
tigations.
