INDEX. 



The plants enumerated below are, with few excep- 

 tions, easily procured, either from woods, fields, or 

 shrubberies, or from gardens ; they should be used in 

 a fresh state when possible, though many may be dried 

 flat between paper so as to shew their instructive parts. 

 Some, as wheat-ears, acorns, peas, &c., should be kept 

 dry in quantities to be used for exercises ; others, as 

 strawberries and such soft fruits, may be preserved in 

 alcohol diluted with water. Lastly, a few objects must 

 be had of a dealer who prepares slices of woods, starch 

 grains, &c., for the microscope these are marked with 

 an asterisk (*).
