M. de Bossanelle, captain of cavalry in the regiment of Beauvilliers, relates in his ‘Military Observations,’ printed in Paris in 1760, ‘that in the year 1757 an old horse of his company, that was very fine and full of mettle, had his teeth suddenly so worn down that he could not chew his hay and corn, and that he was fed for two months, and would still have been so fed had he been kept, by two horses on each side of him that ate in the same manger. These two horses drew hay from the rack, which they chewed, and afterward threw before the old horse; that they did the same with the oats, which they ground very small and also put before him. This was observed and witnessed by a whole company of cavalry, officers and men.’
