This need has been met in the handy calculations of Mr. 

 Morison, showing the profits to be anticipated from the sale of 

 mbbcr at respectively Is. 8d. (40.54 cents), 2s. (48.65 cents)

 \alue of rul)ber shares, and this has been accomplished in the 

 iHKiklet — 13 X 3 inches in size — compiled by Mr. Morison.
