Some human bones lay in the midst of these memorials of human wealth. Unfortunately, they have been scattered.
We can not leave the antas of Portugal without mentioning the bowls which M. Cartailhac observed on some of the megaliths of Alemtejo. Such vessels have long been known in prehistoric archaeology. They are found in Switzerland, in the Pyrenees, in Brittany, in Scotland, in Scandinavia, and on the rocks of Hindostan. The bowls, engraved on the walls of some of the crypts, recently disengaged from their earthy envelope, have doubtless, as M. Cartailhac observes in relating his discovery, an indisputable antiquity, value, and meaning; but we can not determine the age, and the value and meaning are unknown to us. Megaliths are especially abundant in Estremadura, the richest province in Roman Spain, now the most wretched and

A most remarkable example of these works is situated at Equilaz, on the road from Vittoria to Pampeluna. The chamber is of a horseshoe-shape, 5·70 metres long and 4·50 metres wide. It was crowned by a single stone, which had been broken recently. Another, nearly similar, with an approach covered with three large flat stones, and a narrow entrance-way, is still to be seen at Caugas de Oñu, 60 kilometres from Oviedo. We also mention the megalithic

Both of these are placed in the center of a cromlech formed of stones planted in a standing position. The ruins of the covered ways giving access to the crypt are still visible. Thirteen megalithic crypts are described as remaining in Andalusia and the ancient kingdom of Granada. The structures were formerly much more numerous; but they have been destroyed in the processes of agriculture or in the search for minerals. Such a fate has overtaken the important monument of Dilar, two leagues south of Granada.
