The seeds of the sycamore afford a pleasing instance of the care that nature takes for the preservation 
of her infant germs. In the seeds (soaked in warm water) we shall find the radicle and long radicle 
leaves of the future plant folded up in an extraordinary manner, with the minute leaves that are to succeed 
them folded in their bosom ; these radicle leaves are beautifully green, a circumstance not to be expected, 
as all light is excluded by three coatings and a woolly wrapper that invest them. 
The pollen affords a curious object for the microscope. It appears globular ; but if touched with mois- 
ture, these globules biu-st open with four valves, which assume the form of a cross. 
The black blotches which disfigure the leaves of both species, are caused by a minute fungus, Erineum 
acerinum. 
The Maple supports the larva of Lophopteryx cucuUa, (the Maple Prominent ;) Ptilophora variegata. 
Apatela aceris, (the Sycamore Tussock.)
