A certain Dr. Jeffries offered to accompany Blanchard. On the 7th of January the sky was calm, in consequence of a strong frost during the preceding night, the wind which was very light, being from the north-north-west. The arranged meets were made above the cliffs of Dover. When the balloon rose, there were only three sacks of sand of 10 lbs. each in it. They had not been long above ground when the barometer sank from 29.7 to 27.3. Dr. Jeffries, in a letter addressed to the president of the Royal Society, describes with enthusiasm the spectacle spread out before him: the broad country lying behind Dover, sown with numerous towns and villages, formed a charming view; while the rocks on the other side, against which the waves dashed, offered a prospect that was rather trying. They had already passed one-third of the distance across the Channel when the balloon descended for the second time, and they threw over the last of their ballast; and that not sufficing, they threw over some books, and found themselves rising again. After having got more than half way, they found to their dismay, from the rising of the barometer, that they were again descending, and the remainder of their books were thrown over. At twenty-five minutes past two o’clock they had passed three-quarters of their journey, and they perceived ahead the inviting coasts of France. But, in consequence either of the loss or the condensation of the inflammable gas, they found themselves once more descending. They then threw over their provisions, the wings of the car, and other objects. “We were obliged,” says Jeffries, “to throw out the only bottle we had, which fell on the water with a loud sound, and sent up spray like smoke.” They were now near the water themselves, and certain death seemed to stare them in the face. It is said that at this critical moment Jeffries offered to throw himself into the sea, in order to save the life of his companion. “We are lost, both of us,” said he; “and if you believe that it will save you to be lightened of my weight, I am willing to sacrifice my life.” This story has certainly the appearance of romance, and belief in it is not positively demanded.
