6. It feems to be a kind of Marie, or to have great affinity 
with it 5 of which we here alfo have great ftore, yet not near 
thofe places, where I have found oflmoRa* 
7. It requireth alfo time to come to maturity s which appears 
from hence, that in the very (lime place, where I digged fome of 
it the laft year, I this year found others yet with this difference, 
that thofe were grown hard , after the manner before defcri- 
bed, but theft remain ftill foft and friable, though now in 
the fifth Moneth. 
8. The caufe of its being divided into fo many branches , I 
conjecture to be from the Roots, which fpread themfelve* here 
and there in the Earth, fo that the matter gathers and fetleth its 
felf about them, and afterwards according to the divifion of the 
roots, acquires a plantal form and appearance. Whence it alfo 
feems to proceed, that through the midft of the OjleocoSa there 
alwaye s paffeth a dark line, which is thought to be a piece of the 
Root, And it often happens, that that ftrokelofethitfelf by 
little and little , and the ofeocolla in the middle grows clear 5 
which comes to pafTe, when the Root by the corruption, begun 
in the ofteocolU y is reduced to powder. Yet have I found a 
place hereabout, where the ofieocolla was not hollow at all 5 but 
there I obferved, that in ftead of fetling about a big root, it had 
gathered it felf about many fmall fires - 7 whence alfo this fort 
had acquired pores thorough its whole length, but no cavity , 
like the other. 
On another occafion I may alfo communicate to you fome 
particulars concerning the Gramen Jf"h*mon , calFd by others 
Cramen Dactyloidcs , or Sanguinella^ and the Gramen Aquati- 
curn cum longifima pannicula, mention'd by Bauhinm^nd grow- 
ing here in great plenty ^ as alfo the Obfervabies in the Fore/t, 
called the Hartz,, which I intend fhortly to vifit, and wherein are 
to be found very confiderable both Copper and Stiver- Mines , 
ftore of: Lapis ffilis^ and a fort of ftone, which by Raine grows 
altogether foft, and a place, calPd Bawmans Bole, like that of 
Oky-hole about Wells in England, &c. 
I fliall now conclude with giving you notice, that the 1. of
