THE VICTORIAN NATURALIST, 



The constituent parts of lichens are few, and the wonder 

 constantly grows as we examine them how such an immense 

 variety can be produced from such simple and scanty materials. 

 The thallus, composed in even the highest forms of only four 

 layers — cortical, gonidial, medullary, and hypothalline — is yet 

 most surprisingly multiform, and the apothecia are wonder- 

 fully diversified. The same may be said of the thecae or spore 

 bags contained in the apothecia. The spores, too, vary in size,, 

 shape, colour, and markings beyond all expectation. Many are 

 most beautiful objects under the microscope. Some are almost 

 visible to the naked eye, and others test the powers of the best 

 object glasses of J inch or i inch, being smaller than the ten 

 thousandth part of an inch ; and the spermatia are even more 

 minute than the spores, and very various in shape. 



If there are any members of the Club who would like to- 

 prosecute the special study of this branch of botany, I shall be 

 pleased to show them my collection, and to give them any aid 

 in my power ; and I will gladly contribute a paper now and 

 then upon this branch of cryptogamic botany, which deserves ta 

 be better known than it is.
