smooth fragments of various sizes, sometimes scaly, sometimes massive. At the accessible points of the iron block, we found no trace of this substance anymore; However, I think it should be considered as a crust of the meteorite, which was detached by the shaking or temperature change, perhaps also by the efforts made during the first removal.

We have peeled the granite in various places, but nowhere do we find anything resembling an iron deposit, so our opinion of the block's meteoric origin has been taken for granted. Once we had established ourselves in this belief, it was of the utmost importance to acquire fragments of this colossal meteorite; but then we encountered unexpected difficulties. Our limes and saws soon became unusable, after penetrating some lines into the metal; By means of wedges, the isolation of the isolated parts cannot be effected by the holes and grooves, so that we could only resort to repeated hammering. The block, in fact, was different in several places, which seemed to indicate an uneven degree of cohesion, perhaps even cracks in the interior; The worst thing was not to get, after marching all day, a single piece, because all the more easily separable protrusions had already been taken by a worker who had wrought the iron, finding it very useful for his office. After so many sacrifices, nothing could be more unpleasant to us than the inadequacy of our instruments, and our embarrassment increased, as no drop of water was found within two hours, and so we were obliged to send daily water to our horses at Anastacio Farm. On the second day we piled a high bonfire over the metal mass, and for twenty-four hours we kept a fire alive; Thanks to that and the reward we promised the worker, we finally got on the third day several fragments of a few pounds in weight, the largest of which is kept in the Munich Museum. In the cutting of these pieces, we were immediately struck by the crystalline texture of the whole mass, as well as the fact that certain parts of the interior showed a kind of conchoid surface in the cracks, which gave reason to suppose that the surface fusion and the intimate joining of the component parts was initially less

compact. In these cracks appeared, here and there, particles of magnetic pyrite; but in the rest of the mass, there is no chrysolite, which is so common in metal meteor blocks, or other components. In jagged and sometimes almost branched and scratched fractures by the lime, the pieces are white, silver in color. The structure indicates incomplete crystallization, and some crystal faces prove to belong to the octahedral form.
