It is not only the gross parts whose measurements are given. The finer measurement details of each and every part like head, forehead, ears, eyes, nose, thigh etc. are also given for which the reader is referred to the references given above.

Aeronautics . Even the early Jaina texts describe about the planes flying in air. They have circular, triangular and quadrangular shapes. They may also haves squared, svastika, conch, lotus, swan and eagle shapes. 12 They may have different colours. They can be used for travel and temporary residence also. There may be some planes moving in water also. Their sizes are variable but the general length to breadth ratio is approximately 4 : 1.13 The airport should have a size of 11 times the length of the planes. 14 Bharadwaja has refered two sanskrta texts 'Agastya Sanhitā' and 'Yantra-Sarvasva' containing a section on aeronautics. This section has 8 chapters, 100 sub-chapters and 500 aphorisms or verses. The details of its contents can be found in the introduction of Detailed History of Jaina Literature, vol. 5 (PVRI, Varanasi, 1969, Hindi) which have not been studied properly. The technical Sansksta scholars should come forward in this matter.
