“ If the reproductive elements start with a specific protoplasm con- 
tinuous with that of the combined mother ovum and fertilising sperm, 
that is, with a concentrated accumulation of characteristic auastates aud 
katastates, the simple fact that the products of protoplasmic chauge must 
be fixed, definite, aud continuous, as in all chemical processes, gives us 
at once a protoplasmic basis from which to explain the constant and 
necessary symmetry of segmentation and development. And further, 
since all the organs of the body do, to a certain extent, share mutually 
iu nutriment aud in waste products, both germinal cells and developing 
embryo may accumulate a proportion of characteristic anastates and 
katastates, acquired, as it were, “ pangenetically ” from the organs of the 
body.”

“As in malformations or in development of supernumerary members, in 
regard to which inheritance has been frequently observed, so is it in 
regard to tumours; in both cases tho cause is deficiency in the embryonic 
rudimeut, or a superfluous production of embryonic material.

Supplement to previous paper on importance of nucleus {loc. cit. 1885), 
and critique of Weismann. (1.) The idioplasm in nucleus of fertilized 
ovum increases in mass as the development proceeds, but transmits its 
internal structure unchanged to the nuclei of all the cells forming the 
embryo. Deep difference between somatic and reproductive cells denied. 
(2.) Iu the various cellular modifications the characteristics of the 
original nuclear idioplasm may be wholly retained, or degenerate, or 
be wholly lost.

. Historical note in reference to above distinction, of late so much 
emphasized, but proposed by Haeckel in 1874, aud Rauber in 1879.
