Cocktails: How to Make Them

No publication date printed in book, but internal evidence strongly suggested 1930s, this edition appears to be a reprint from the 1950s.

Martini Cocktail
Here is the exact recipe:
Fill the bar glass half full with broken ice and add:
1 dash orange bitters
1/6 gill of Italian vermouth
2/6 gill of dry gin
stir up and strain into a cocktail-glass, squeeze lemon-peel on top.

Medium Martini
1/4 gill of gin
1/8 gill of Italian vermouth
1/8 gill of French vermouth

Sweet Martini
1/4 gill of Italian vermouth
1/4 gill of gin.

Note.--The Martini Cocktail should be prepared in the mixing glass and stirred up. In America, however, it has been the fashion, since a few years, to shake this cocktail until throughly cold.
