Captain Ian Hay Beith, British soldier and author, will lecture on "The Human Side of French Warfare" in Sanders Theatre this afternoon at 4 o'clock. Tickets at one dollar may be obtained at Amee's and at the door, the proceeds of the lecture going to the Cambridge Surgical Dressings Committee, which supplies medical materials for the Harvard Surgical Unit in France.

Captain Beith was just under the maximum age limit for enlistment at the outbreak of the war and immediately enrolled in the Tenth Argyll and Sutherland Highlanders, which went into training at Aldershot in the fall of 1914. The regiment remained in training for six months and were finally sent to the front in the spring of 1915 as members of the first detachment of England's volunteer army. Captain Beith's ability and courage soon won him a commission and he rose rapidly to the rank of captain. He has recently been granted a furlough by the British War Office to lecture in this country on England's part in the war and has already spoken at several universities and colleges, including Yale and Princeton, and at several preparatory schools.

In his book, "The First Hundred Thousand," written under the pen-name of Ian Hay, Captain Beith has collected his most interesting and entertaining experiences at Aldershot and "somewhere in France" as typical of the life of a British volunteer.

Captain Beith is the official lecturer of the British government at the Allied Bazaar in Boston, and with Captain Norman Charles Thwaites, V.C., is in charge of the British military exhibits in Mechanics Building.
