有人知道其具体出处么

Count not your Chickens before they are Hatched.Generally ascribed to Lafontaine,from his fable of the milkmaid Perrette.But the substance of this fable is very old.For example—
In A.D.550 Barzûyeh translated for the king of Persia a collection of Indian fables called the Panka Tantra (“five books”),and one of the stories is that of a Brahmin who collected rice by begging; but it occurred to him there might be a famine,in which case he could sell his rice for 100 rupees,and buy two goats.The goats would multiply,and he would then buy cows; the cows would calve,and he would buy a farm; with the savings of his farm he would buy a mansion; then marry some one with a rich dowry; there would be a son in due time,who should be named Somo Sala,whom he would dandle on his knees.If the child ran into danger he would cry to the mother,“Take up the baby!take up the baby!” In his excitement the castle-dreamer kicked over his packet of rice,and all his swans took wing.From this fable the Persians say of a castle-dreamer,“He is like the father of Somo Sala.”
Another version of the story is given in “The History of the Barber’s Fifth Brother,” whose name was Alnaschar (q.v.).—Arabian Nights’ Entertainments.
Rabelais has introduced a similar story,called “The Shoemaker and a Ha’poth of Milk,” told by Echephron,in Pantagruel.
