Here ends the marking with the nails. Marks of other kinds than the above may also be made with the nails, for the ancient authors say, that as there are innumerable degrees of skill among men (the practice of this art being known to all), so there are innumerable ways of making these marks. And as pressing or marking with the nails is independent of love, no one can say with certainty how many different kinds of marks with the nails do actually exist. The reason of this is, Vatsyayana says, that as variety is necessary in love, so love is to be produced by means of variety. It is on this account that courtezans, who are well acquainted with various ways and means, become so desirable, for if variety is sought in all the arts and amusements, such as archery and others, how much more should it be sought after in the present case. The marks of the nails should not be made on married women, but particular kinds of marks may be made on their private parts for the remembrance and increase of love. There are also some verses on the subject, as follows: "The love of a woman who sees the marks of nails on the private parts of her body, even though they are old and almost worn out, becomes again fresh and new. If there be no marks of nails to remind a person of the passages of love, then love is lessened in the same way as when no union takes place for a long time." Even when a stranger sees at a distance a young woman with the marks of nails on her breast,[37] he is filled with love and respect for her. A man, also, who carries the marks of nails and teeth on some parts of his body, influences the mind of a woman, even though it be ever so firm. In short, nothing tends to increase love so much as the effects of marking with the nails, and biting. FOOTNOTE: [Footnote 37: From this it would appear that in ancient times the breasts of women were not covered, and this is seen in the painting of the Ajunta and other caves, where we find that the breasts of even royal ladies and others are exposed.] CHAPTER V. ON BITING, AND THE MEANS TO BE EMPLOYED WITH REGARD TO WOMEN OF DIFFERENT COUNTRIES. All the places that can be kissed, are also the places that can be bitten, except the upper lip, the interior of the mouth, and the eyes. The qualities of good teeth are as follows: They should be equal, possessed of a pleasing brightness, capable of being coloured, of proper proportions, unbroken, and with sharp ends. The defects of teeth on the other hand are, that they are blunt, protruding from the gums, rough, soft, large, and loosely set. The following are the different kinds of biting, viz.: The hidden bite. The swollen bite. The point. The line of points. The coral and the jewel. The line of jewels. The broken cloud. The biting of the boar. (1). The biting which is shown only by the excessive redness of the skin that is bitten, is called the "hidden bite."
