peace of 1814, had been traveling on the continent, and ar- 

 rived at Calais, with a view of crossing the channel to Dover ; 

 they were, however, detained several days by the inclem- 

 ency of the weather. They attempted to get to Boulogne, 

 to try the chance of a passage from there, but the vessel in 

 which they embarked was forced to put back. To pass 

 time, they agreed to take horses, look around the country 

 and view a fort near Bonaparte's pillar. At the entrance 

 of this fort was a deep fosse, which w^as approached over a 

 fixed bridge, and then over a drawbridge, that turned upon 

 a pivot; the end nearest them was commonly fastened by a 

 bolt, but it happened that this had been stolen a fortnight 

 before, and had not been replaced. They did not discover 

 this. As the bridge was too narrow for both to ride abreast, 

 the Baron w'ent first, but perceiving that the bridge was 

 sinking, he attempted to gallop over, and called to his friend 

 to go back. It was too Lite ; both were precipitated into 

 the fosse, and though his companion was hardly hurt, Pro- 

 fessor Tennant was taken up from under his horse, and 

 died a few hours after.
