not think it is necessary at all to make as many little side panels as were made at Bologna by my friend Capellini. N.B.: Let me particularly request you to remember that the opening through which the steel supports which carry the neck, body, the legs, and the fore part of the tail, as shown in these plans, should not be bored by the cabinet-maker, but that these openings should be left to be made by our master-workmen, who will come to Mexico when you are ready in order to install the specimen. While these openings are shown in the plans I think it is highly important that they should not be made by the cabinet-maker, who may be employed by you to construct the bases, the exact location together with the size of the openings is best determined by workmen when they arrive upon the spot. So please bear in mind in submitting the plans to whomever you select to build the cases that the cabinet-maker should be enjoined while doing all the rest of the work not to make the openings for the upright steel supports. We will bore them when we come to set up the specimen. Furthermore, I beg you to remember that the tops of all of these bases are made separately and are not put on until after the specimen has been erected in place. You will see, therefore, that these tops should be made in parts, the lines of division of the tops coinciding with the lines through which the upright supports come. The tops will be fitted on by the cabinet-maker after the skeleton has been set up. Perhaps I can best illustrate this by a little diagram, which I am herewith enclosing. I think that I have made myself perfectly clear to you, but if there is any information which you require, or any point in reference to which you are in doubt, kindly communicate with me.
