One of thefe Plants, whofe branch feem’d to be older and 
more grown then the other, onely the tender Sprouts of it, after 
the leaves are fhut, fall and hang down ; of the other, the whole 
branches fall to the ground, if the Sun fhine very warm,upen the | 
‘firkt taking offthe Glafs, which I therefore call the humble Plant. 
The other two, which do never fall, nor do any of their 
branches flagg and hang down, fhut not their leaves, but upon

with much lefs leaves then the other on 1 them, and have on 
each {prig, generally feventeen pair. 
~ Upon touching any of the fprigs with leaves on,all the leaves

per fuperficies elofe together. : 
Upon the dropping a drop of Aqua fortis on the fprig be- 
twixt the leaves, f fall the leaves above fhut prefently, thofe 
below by pairs fucceflively after, and by the lower leaves of the 
other branches, 11, Kk, &c. and fo every pair fucceflively, 
with fome little diftance.of time betwixt,to the top of each {prig, 
ahd fo they continu'd {hut all the time we were there, ‘But I re- 
‘turning the next: day; and feveral days fince,found all the leaves
