tion; the third was André; he had five fingers — 
and five toes, quite perfect ; the fourth was a girl, — 
Marie; she had five fingers and five toes, but her

results. Salvator had four children; they were — 
two boys, a girl, and another boy; the first two 
boys and the girl were six-fingered and six-toed 
like their grandfather; the fourth boy had only 
five fingers and five toes. George had only four 
children ; there were two girls with six fingers 
and six toes; there was one girl with six fingers 
and five toes on the right side, and five fingers : 
and five toes on the left side, so that she was half | 
and half. The last, a boy, had five fingers and 
five toes. The third, André, you will recollect, 
was perfectly well-formed, and he had many — 
children whose hands and feet were all regularly 
developed. Marie, the last, who, of course, mar- 
ried a man who had only five fingers, had four 
children ; the first, a boy, was born with six toes, 
but the other three were normal. 
Nowobserve what very extraordinary phenomena 
are presented here. You have an accidental varia- 
tion giving rise to what you may call a monstrosity ;
