be formed collaterally with trichlorotoluidine derivative pro- 

 ducts of substitution of anisole. 



We possess in the indigo, salicyle and phenyle families, 

 well-examined groups of organic bodies, which are in the most 

 manifold manner connected with each other. There appears 

 to be parallel with these another extended series of corre- 

 sponding compounds, which differ only in Cg Hg, but as yet 

 there are many interruptions, so that the group of indigo is 

 entirely wanting. 



In toluidine we have described one member which hitherto 

 was unknown; the others requisite will also certainly be dis- 

 covered before long. 



The following is a view of these two series of compounds : — 



Indigo, Salicyle and Phenyle series. Anisyle series, &c.
