APPENDIX. 



It appears the most conv^enieut arrangement to put the followiiii^ 

 Tables in an Appendix by themselves, as referred to in ditiorent 

 parts of the work. 



Tables I. — IV. are slightly altered from those appended to my 

 paper on the Genetic Cycle, in the Edinburgh Philosojihicjil 

 Journal for January, 1860. Table V. is a modification of quo 

 given by Dr. Sanderson, in the Cyclopaedia of ^Vnatomy ami 

 Physiology (Art. Vegetable Ovum) ; the explanation ai)pend«.d 

 to it shows in what resjiects his views have been departed from. 



The three succeeding give a conspectus — arranged a.s much ii."< 

 possible in the same plan, for the sake of comparison — of tlio 

 theory of relations which I have been led to adopt in thi« 

 work.
