 Attention must be paid not to let the foam of the soda water spread over the glass.In the 1884 book, "The Modern Bartender’s Guide" by O. H. Byron there is a drink called a “John Collins’ Gin” where he calls simply for gin with no specifications of which gin, lemon juice, sugar, and filled with soda.That book also has a “Tom Collins’ Brandy”, which consists of brandy, lemon juice, gum syrup and Maraschino liqueur, and filled with soda water built in the glass over ice.
