1870
Due to heightened interest in rugby in Scotland, pressure mounted to play an international match. Following a meeting on 5 December, representatives of four Scottish Clubs (EAFC, West of Scotland, Glasgow Academicals and the University of St Andrew's), wrote to B H Burns, the Secretary of Blackheath, "...For our own satisfaction, therefore, and with a view to really testing what Scotland can do against an English Team, we, representing the whole footballing interest of Scotland, hereby challenge any team selected from the whole of England, to play us a match, twenty a side Rugby rules. If entered into we can promise England a hearty welcome and a first rate match."

27 March - A then record crowd, estimated at about 4,000, attended Raeburn Place. Scotland won by the only "goal" (i.e. conversion), by W Cross. One anecdote is "J F Finlay had got away well with the ball and was sprinting towards the English line at hundred yards speed when Osborne, folding his arms across his chest, ran full tilt at him, after the fashion of a bull charging at a gate. Both were very big, heavy men, and the crash of the collision was tremendous, each reeling some yards and finally falling on his back. For a few seconds, players and spectators alike held their breath, fearing terrible results, but the two giants promptly resumed their places, apparently none the worse." James Finlay played in every International afterwards until his retirement in 1875. The legendary R W "Bulldog" Irvine played in that first match, at the age of 18, and appeared in every match for the next 10 years! Ninian Finlay also played in the Match, having just turned 17 - Scotland’s youngest cap. Internationals continued to be played at Raeburn Place until 1899.
