lie founds his Notion, he prefumes his thoughts on this fubjeG will 
not be altogether unacceptable. 
He takes notice therefore, that 'tis the general opinion, that the 
Matter of both thefe evacuations is the fame^ and that they difter 
only according to the greater or lefs proportion of the Matter ex- 
cluded, and that thefe perfons thence form an Indication of 
curing moft Difeafes by Sudorificks. Biit he being of a very dif- 
ferent notion, endeavours to make it out from fome confiderations 
andreafons. 
And Wirft^ He confiders, that the Matter defign'd by Nature to 
be evacuated at the pores in the Skin^ is of two forts, viz. Either 
the fuperfluous Serum^ or other Subftances v^/hich make up the 
Blood, which, on the account of their Figures and Bulk, when im- 
pelled by the Heart, are adapted to pafs through duly figured 
Strainers, which they find there ; Or elfe, the particles of the Nu- 
tritiom J nice ^ which having either been affimilated, bur now 
become effete, or been brought in a larger quantity than the Nutri- 
tion of the part requires, muft ftill gu on to the extremities of the 
VelFels that carry them, till the continued protrufion from above 
calls them forth. 
Thefe two Liquors he takes to be of very different kinds : The for- 
mvr conllils of very various fons of particles ^ the latter^ tho' not 
limply homogeneous, yet he fuppofes to be lefs heterogeneous 
than the others : And befides, conceives they muft be carried aloiig 
by very different degrees of motion. 
Secondly^ he confiders, . That, as thefe Subftances are fo very 
different, fo,- he thinks, 'tis requitite there fhould be two diiFerenc 
manners of their exclufion ^ one by means of Secretion^ tlie other 
by a bare Vrotrufton, As to the former, he -thinks it probable, 
ffeac fince the particles of the Mafs that affords ihefe, viz. the 
Blood, arefo very heteiogeneoiis, and this mafs' fo briskly agitated, 
'tis neceffary a determinate organization and mfchanilm of fom@.
