bent so as to pass down the neural canal. The 

 skull too, was fastened to this iron support, 

 which in turn was fastened to the strong sup- 

 ports that were to secure the skeleton to the base. 

 Although this is the most complete skeleton of a 

 Titanotherium with which I am familiar, there 

 were several missing bones. We secured a box 

 full of duplicate material from the American 

 Museum, and we succeeded in finding nearly 

 enough to complete some of the feet. We found 

 however, that we had only one femur and one 

 radius and ulna. So we were obliged to attempt 

 another trade with which we were not familiar, 

 that of modeling the missing bones in clay. And 

 then making a cast of them to replace the missing 

 ones. When I attempted to make a femur in 

 wax using as my model the bone we already had, 

 I found difficulties I had not bargained for. It 

 would have been comparatively easy to have 

 made a copy of the one we had, but it would have 

 been useless. In other words I must make one 

 exactly the reverse of the model, i. e., if there was 

 a great trochanter on my model, I must put it on 

 the reverse side on my wax copy, or as I told 

 George, I must think exactly opposite to what 

 the model was, like thinking backward. In other 

 words the mental picture I must follow, would 

 be the reverse of the femur I was looking at. It 

 seems we both overcame these difficulties. We 

 made one mistake however, I have been sorry for, 

 and hope to rectify, and that was we followed
