Twenty-eighth report of progress of excavations by William Pengelly and Edward Vivian, Torquay, to the British Association Kent's Cavern Committee Monthly report of the superintendents of exploration. The excavations are ongoing in the 'Lecture Hall''. There is a deposit of breccia thought to be of high antiquity. Within the breccia, there are many bones and teeth from cave-bears, with one exception. 'Some of the canines of ursus spelaeus are of a great size,' and it is thought they were used for mastication in lieu of lost molars. The exception is a tooth of a cave hyena. Across many days, teeth have been found from: hyena, horse, bear, rhinoceros, fox, mammoth, and deer. Several bones contain teeth marks and some are cut longitudinally. 1 November 1867
