inch in diameter, and the largest are about rfoo P art °f an 
inch in diameter ; the number of large fungi, in proportion to 
those of the ordinary size, is as 1 to 100; but in the newly 
formed sediment, after the above described experiments, I 
found many of the larger fungi to be as large as part 
of an inch in diameter, and the number of large fungi, in 
proportion to those of the ordinary size, as 1 to 10. 
I also found that, notwithstanding the snow in the glass 
had so frequently been changed, and though the fungi had 
sometimes been not more than three or four davs in the snow, 
the water, after the snow was dissolved, always acquired 
the same disagreeable smell and taste as the original water 
imported from Baffin’s Bay. 
The above described experiments I attempted to repeat on 
a larger scale, and for that purpose I employed a glass of 
about twelve cubic inches in contents. The original red 
sediment which it contained was about f of an inch in thick- 
ness ; and after marking on the glass with a diamond the 
precise height of the whole mass, I drained off the water, and 
divided the sediment in three equal parts; on the 12th of 
January, 1820, I put the different portions of sediment into 
three equally sized glasses, which I afterwards filled and 
pressed with snow, and exposed them in the open air, as in 
the former experiments. 
The first few days, the weather continued very cold and 
favourable for the experiment, and the appearance in the 
glasses was the same as in the former experiment. The 
fungi in some glasses had risen and spread in rays and 
pyramids of near three inches in length, and the increase 
appeared considerable and rapid ; but during the day of the
