Health, till the Period of their falling to the Ground. 
I have now by me the Filament of a Plant, laid by 
for Obfervation ever ftnce October the 28th laft paft, 
which is near half a Year ago ; from which, two 
Days ago, 1 took Seeds fair and perfed. 
3. Upon Examination of the Caulis in feveral 
Sections, I find the Mufhroom a Plant more perfect 
than has been thought. It has a perfed Radix ; a 
Caulis confiding of Fibres, the Interftices of which 
are filled up by a parenchymous Subftance, leading 
fronp the Radix to the Umbella or Head : It has, as 
has been obferved, its Semen and Siliqua-, and more 
regular Periods of Vegetation than is luppofed. The 
common Opinion of a Mufhroom’s fpringing up in 
a Night, and perifhing in a Day, has no Foundation 
in Fad. I have now by me fome in all States of 
Maturity ; fome of which, to my Knowlege, are 
near a Fortnight old, and yet but juft arrived to a

posed to the open Air, but kept from the Injuries of 
the Sun and Rain, I find no Animal cula bred therein, 
nor, as yet, a Tendency to Putrefadion; though 
they have been expofed thus for a Week. On the 
other hand, upon examining a Mufhroom, very far 
from being full-grown, putrefy 5 d by the Rain, and 
Moifture of the Dung in the Bed, I found Animal- 
cula , difcoverable only by the third Magnifier, float- 
ing in the Liquor, fqueczcd out from it : From 
which I think it evident, that the dangerous Confc- 
quenccs which Hiftory has informed us to have 
attended the Eating of Mufhrooms, have not arofe.
