LXXVIII. : 9"5 centimetres wide, I'O decimetre high, and 

 6*0 centimetres deep ; lined with white paper. 



LXXIX. : Similar, only I'l decimetres wide ; lined with orange 

 paper. 



LXXX. : Similar to LXXVIII. ; lined with blue paper. 



LXXXI. : Similar to LXXIX. ; lined with black paper. 



LXXXII. to LXXXV. Four compartments of wooden box,

 otherwise similar.

 1*35 high, and '56 deep), covered with a sheet of clear glass, and 

 lined throughout with black and orange squares of equal size, 

 regularly alternating. Each was \1-HS nnn. square, and thus a size
