skeleton. Your telegram inquiring as to the materials of which the reproduction is composed was answered by me in a long letter, which I wrote you accompanied by a lithograph of the skeleton showing its features, and the supports upon which it is placed. No attempt was ever made my Mr. Carnegie to present a reproduction in the flesh in bronze. Such a reproduction exists nowhere in the world, so far as I know. The only approach to tit is a reproduction, which was palced by the late Mr. Hagenback in his private park at Stellingen, near Hamburh. This replica is made of cement and is constructed after a small model which I sent him accompanied by the dimesions in life of the creature as it may possibley have appeared. I saw this reproduction at Steelingen before the ware, and was somewhat amused by it. While it is certainly huge it is at best only an attempt to visualize the monster. Teh specimen, which Mr. Carnegie has given to the scientific museums of the world has genuine value in that it reproduces in every detail the ostelogical characters of the creature as the skeleton was found imbeeded in the clay from which we extracted it. The specimenis, of course, not adapted to display in open air where rain and frost might very soon lead to its deterioration and destruction. It is a scientific model. The original remains so far the only representative of a complete skeleton which exists in any museum in the United States. You speak of 'regretting your inability while in the United States to visit Chicago and other localities were the Diplodocus is shown.' It may interest you to know that they have no replica of the skeleton of the Diplodocus in Chicago, nor for that matter in any other American city or museum. Mr. Carnegie declined to allow replicas to be presented to more than one Museum in one country,
