We collected "lauhas" which have undergone different number of "putas" for analysis. The colour of these samples varied from greyish black and grey to orange-red. It was observed that one "puta lauha" was greatly attracted by a magnet, "lauha" which has been calcined ten times was attracted to a less degree, while a sample of seventy-eight "puta lauha" was very slightly attracted. As regards iron which has been calcined hundred or thousand times, it was not in the least attracted by a magnet.
