[340] As with the castoreum of the beaver, see Mr. L. H. Morgan’s most interesting work, ‘The American Beaver,’ 1868, p. 300. Pallas (‘Spic. Zoolog.’ fasc. viii. 1779, p. 23) has well discussed the odoriferous glands of mammals. Owen (‘Anat. of Vertebrates,’ vol. iii. p. 634) also gives an account of these glands, including those of the elephant, and (p. 763) those of shrew-mice.
