Charts explaining the method of collecting and recording data. 
Exhibited by Mr E. J. Lidbetter. 
A selection by Mr. E. J. Lidbetter, from his collection of 
pedigrees, showing pauperism in association with mental and 
physical defect, justifying the inference that a high proportion of 
pauperism is to be attributed to the transmission of defect and the 
perpetuation of stocks of a low type :— 
Pedigree showing mental disease and destructive eye-disease 
in the same stock. Insanity, epilepsy, feeble-mindedness and idiocy 
in various degrees in twelve members, several of them being also 
blind; partial or total blindness from detachment of the retina with­

“ anticipation ” of the mental disease, in succeeding generations or 
younger born offspring. The printed numbers on the diagram indicate

Blind Schools, or Poor Law Schools), 29 have been paupers at intervals,

mental defectives yielding large but inferior families. (Exhibited 
by Mr. E. J. Lidbetter. The eye-disease reported upon by Mr. E. 
Nettleship.) Pedigree showing the tendency to intermarry among pauper 
and defective families. On the left “ able-bodied ” pauperism and

nine tuberculous, six insane, two epileptics, and one blind. Shows
