[qirdwood] right and LEFT HANDEDNESS 191 



.sudden thunder ptorni destroying a whole sitting of eggs shows tlie 

 influence of electrical phenomena on early life, and then there is the 

 constant radiation from the earth's surface of radium, any of wliich might 

 be suflicient cause. Or must we still go back to protoplasmic memory. 



If the a\erages noted in these thoughts and observations are borne 

 out and verified by other observers, the natural result would be to breed 

 out white-legged horses, and in the meantime for governments to refuse 

 to purchase them. In the selection of seeds for the propagation of 

 plants, seek out those that hav'3 been gron-n earliest and on the right side 

 of carpellary leaf. 



The first evidence which may solve the riddle found in Crystalline 

 bodies — it is well known that the asymmetric carbon atom in organic 

 compounds determines whether the plane of polarized light be rotated to 

 the right or to the left, or whether the amount of asymmetric right and 

 left-handed rotation be equal we have an inactive compound which does 

 not affect the plane of polarized light. 



Starch and sugar are most plentifully present in the vegetable 

 kingdom. 



Starch has the formula, CgHi^Og 



in endless varieties of plants. 

 Dextrin in varieties of plants, CgHigOj 

 Inuline, Dahlias and artichokes, CjHijOs 

 Moss starch. 



Inuline, Dahlias and artichokes, CgH^oOg 

 Glycogen animal starch, CgH^oOg 



Glycogen, being found in the mollusca — in the surroundings of the infant 

 in embryo — and is leave notary. 



Both converted into grape sugar by the action of acids, and as 

 sugar turns the ray of polarized light to the left or right, according as it 

 is dextrose or lévulose, here is a connecting link between the animal and 

 the vegetable, and from its action, as rotating the plane of polarized 

 light, it might be the means of determining the growth to one side or 

 the other. These are only hints, not even hypotheses.
