pearance of the flowers of Typha Major ; every part of the 
plant worthy of attention. Species of Carex not eafily difiin- 
guiflied from each other. Carex Pendula distinctly marked 
by the long pendant Aments of it's flowers. The Catkin tribe 
of flowers merits attentive examination ; manner of investi- 
gating Araent-bearing plants. 163, Cryptogamia clafs. Sta* 
mens and pistils not yet difcovered in the Cryptogamia clafs. 
Meaning of the term Fructification, as applied to the plants of 
Cryptogamia. The Filices, or Ferns, divided into three feetions, 
by the difpofition. of their fructifications. Radical Fructifica- 
tion explained, well feen in Pilularia. Hedwig's botanical 
refearches, in clafs Cryptogamia, of great importance, 
164, Equifetum Sylvaticum, a good fpecimen of the fpiked 
fructification of Ferns. Extraordinary appearance of the fup- 
pofed feeds of Equifetum magnified drawings a great aflift- 
ance in the investigation of obfcure plants. Plates not wholly 
to be relied on. Little progrefs made in any fludy by thofe 
Who rely on the authority of others. The rule (( See for your- 
felf," to be obferved in all studies ; Mr. Curtis's works rendered 
valuable by the obfervance of this rule. 165, His candid cor- 
rection of the few errours of Linneus, of elfential fervice to 
the botanical world. Account of the progrefs pf Equifetum, 
Greenifh powdery mafs fliook from the fpike. Particles of 
powder appear regular formed bodies, viewed in the micro-* 
fcopej account of their form. Regular organization of the 
parts of plants. Curious appearance of the powder fliook 
from the fpikes of Equifetum. 166, Hedwig's opinion of 
this powder; circumstance in favour of his opinion. Scales of 
the protruded fpike of Equifetum, protected the fpikes before 
protrusion. 167, Knowledge of the fructification of Equifetum 
leads to the knowledge of the Fructification of other fpiked 
Ferns. Leafy Fructification : beauty of the maiden hair. The 
parts of Fructification too minute for the investigation of ,young 
Botanists. 168, The larger size of Hart's-tongue, fhows the 
Fructification distinctly. Fructification defcribed 5 wonderful 
mechanifm of the feeds, with their apparatus. Benevolence of
