 fo.mat.ons of pigment, the metamorphoses of the cells containing 

 blood corpuscle,, the depositions of fat in cells of all hinds, etc. 



Manifold morphological phenomena go hand in hand with these 

 changes, such as the above-mentioned thickenings and laminated 

 depositions upon the outer side of the cell-membranes; further
