"Consisting of forty eight pictorial cards illustrative of the Adventures and Games of the Boys of Dr. Lion's Jungle School from Constance Stannard Chapman's Original Designs."
Each numbered cards of the sets are similar, for example number 2 of each set shows an animal with a musical instrument. There are 48 cards arranged in 3 sets of 16, each lettered A, B or C and numbered 1 to 16; all the illustrations are different and have an appropriate title.
A set number of cards are dealt, probably 5, to each player. The object of the game is to complete a set of three cards, one from each letter, for example a set would be cards A1, B1 and C1, not 1 to 16 of A. The player to the dealer's left begins the play by asking his next neighbor on his left side for A, B or C of any set to complete the three cards of the set. When a player has succeeded in completing a set, he must show the completed set, and may then draw a card from the pool but no card must be drawn from the pool except upon the completion of a set, and only one card drawn.
The winner of the game is the one who completes the most sets.
This game is copyright Thomas De La Rue on the box, but the rules say that H P Gibson are the copyright holders. As far as I know, there has never been a reissue of the game so I assume H P Gibson still hold the copyright. However, I am crediting them both with this game. Almost certainly, De La Rue printed it and H P Gibson distributed it.
