gafts of wind,! faw,to my great delight, continually, aiHd with- 
out any other motion but that of the wind, the red GJobu s a-

obferv'd the Blood^^r. furnifhing himalfo fomeof thofefmall 
Glafs-pipes ; which together with my Letter being fent by 
him to his Son at P^m^he had this return from him, that they 
had feen noGlobuls at all in the blood,but other particles.This 
may happen alfo to others,who are therefore hereby ad vercifed 
that thofe red Globuls, {landing ftill, do foon come to ftick to 
one another, fas I have obferv'd my felf more than once,) and 
being thus carried thorow theCryftallin humidity, exhibit odd 
and mifliapen particles -.Which doubtlefs is the reafon,v\hy the

in many places befet with earthy particles and fiiamefits,which, 
without this precaution, might be taken for parts of the mat-

and fliewM to feveral of the Curious, that it is made up of 
Globuls joyn'd together, which appear 'd to my eye as big as 
ordinary hail-ftones : Yet are wc not to fancy, as if there Glo- 
buls, and thofe that conftitute aBone and other folid pari:s,did 
confift of Globu s perfeltly round : For,if that wei e fo,it muft 
follow, that the interftices betwixt fuch Globuls would he tri- 
angular ,or they be fill'd up with other CorpufcIes.Eut you are 
to know,that they are round but on one fide \ as, for example^
