'Dizzy's Arithmetic', 1865. Pam remarks Now, then, Youngster, You've No Call to be a Chalking that Wall; and if You Must do a Sum , You might as well do it Right! Disraeli is depicted as a small boy chalking a sum on the wall. With the 'Libberals' having a return of 368, and the 'Torys' 290, Disraeli manages to produce a solution that gives the Conservatives a majority of 25. Mr Policeman Bull, wearing the face of the victorious PM, Lord Palmerston, scolds him in a genial manner, telling him that he ought at least to get the sum right. The Liberals had regained power during the recent General Election with an increased majority of 78. This was a blow to the Conservatives who faced another term in opposition. From Punch, or the London Charivari, August 12, 1865.
