In the present lecture I propose to allude to the 

 characters of bioplasm as far as thej can be ascer- 

 tained by low magnifying powers, and I shall allude to 

 several points generally, which will be more particu- 

 larly described in Lecture IV. It will be more con- 

 venient to postpone the consideration in detail of the 

 wonderful phenomena of the bioplasm, until the 

 student is acquainted with general facts more easily 

 understood. Nevertheless those phenomena may be 

 observed by any one well acquainted with the use of 

 the higher powers of the microscope. They are of 

 surpassing interest, although not to be explained by 

 science, or accounted for by philosophy. I shall 

 refer to a few simple textures containing bioplasm. 

 If the student will place the structures alluded to 

 under his microscope, he will be able to verify the 

 few remarks that will be made in this place.

 and its bioplasm. — If a leaf bud be examined before 

 any of the green colouring matter has been formed, the 

 colourless bioplasm will be found occupying the 

 cavities or little spaces in the tissue of which the
