mating, a pairing by some subtle vibration; but with no law to 
be followed that would intelligently cry: 
“Halt! This is destruction!” Or that would hail: 
“Come! This is the certain way to race perfection!” 
What grand constructive program could be mapped out for 
mankind with such a law? The tubercular being need not then 
despair of regeneration, for, knowing a Law of Cross-Transmis¬ 
sion and Determination of Sex at Will the weakly father would 
expect strong sons from the healthy mother, from the healthy 
mate chosen under that Law, and until in time his weak strain 
of blood would be reconstructed, regenerated. His then created 
daughters could expect strong sons with healthy mates also 
chosen under that Law. 
Or, to make it still plainer, let us suppose that, apart from the 
mere caprice of desire, there is a practical purpose to be gained 
by having boys and girls at will. Suppose that the wife has the 
taint of tuberculosis in her family. Suppose that the husband, 
on the contrary, is a robust man, with robust lineage. The wife 
is undergoing, we will say, the hygienic process of regenera¬ 
tion by proper nutrition,—as explained later on,—proper 
breathing and other proper care. Now then, the couple are just 
married. They want children. But will the children be tuber¬ 
cular, will they have taint? Not if we follow the Dechmann law 
of the Determination of Sex in a scientific manner. The first 
offspring should be a female, and will, by the law of Cross- 
Transmission of Sex, normally speaking, have.the health of the 
father. So a female is born, and it is like its father. 
A few years have passed now, but we still wait a year or 
two. The mother, meanwhile, is regenerating, and, not 
only that, but, by the law of consanguinity, as a wife, she is al¬ 
ready absorbing some of the quality of the husband’s health. 
At length, the vital question arises: What shall the second 
child be,—a girl or a boy? A girl, certainly, for we must yet 
give the mother a chance to regenerate. And so the 
process gradually goes on. The mother looks well, she is still 
regenerating. She does not look like the mother of old; 
for, as I have told you, nature is not unjust; she gives humanity 
a chance to regenerate, and some of the hereditary traits
