dents equally derivable from the fame conftitution of the Air^nd 
independent the one f^oni the other. But^if this gangrcn feifech on- 
ly on thofe that eat Key- bread , and comes not upon them but in 
fuch years when there is much Rey corruptedj it feems to be cer- 
rain/hat this corrupred Rey is the caufe of this gangren. To af- 
fure our ferves the more of it, the Company gave order to make 
bread both of this Rey a!one,and of the fame Rey mingled in dif- 
ferent proportions with good Rey,toobferve th^ different efFefts 
of this Rey and of thefc difFerenc mixtures upon brutes of dif- 
ferent kinds. And to omit nothing that may ftrve to know the 
caufes of this corruption; M. Marchatsd hath been defired by them 
to caufe fome of chatfandy earth where it grows to be brought, 
and to plant in it fome grains of Rey not corrupted, and to water 
them very much during the Spring, to fee , whether there be fome 
particular caufe of this corruption befides the fuperfluous humi- 
dity. And to give occafion the better to know,wherein confifts this 
corruption , they have defired M. jB^>»r^^//;?i to make a Gbymical 
analyfisof this corrupted Rey , which they intend afterwards to 
compare vYith the Chymical analyfis they have made of good Rey. 
Whilft thefe Experiments are making, I lliall tell you (faith M. 
Dodard)i\i^i UMUier has affured me,that in the year 1 630, which 
was fatal to the poor of the Countries fubj eft to thefe evils, he 
being at Sully^ and having underftood by a Phyfician and Chirur- 
gion,that the cornutedRcy was the caufe of thegangrens that were 
then very frequent, beiag defirous to fatisfie himlelf, whether this 
grain was indeed the caufe thereofjhe gave of ittofeveral Animals, 
that died of it. 
The Company intends toexamine very ftriflly this fort of Rey 
that (hall be brought them from feveral parts , thereby to furnilh 
the Magiftrate with inftruftions to prevent thofe evils that may be 
caufed by this corrupted corn , and to ufe fuch precautions 
as they fliall judge necelTary ; of which the chief may be, to ad- 
vertife the people of this evil, and to oblige them to fift the Rey, 
and to forbid the grinders of corn, to grind any Rey that has 
fuch grains in it, which islbeafie to know, that there can be no 
raiftakeinit.
