some difficulty in carefully determining the exact sequence of 

 strata in Patagonia from the window of his study, situated in 

 La Plata or Buenos Aires. Nor can I agree with Dr. Ameghino 

 that he has satisfactorily answered my appeal to him for the pub- 

 lication of more exact localities by the reply given on page 8, that 

 " Les recherches de C. Ameghino ont ete faites a mes f rais, pour 

 mon instruction personelle et au profit de la science. Je n'avais 

 pas l'obligation de faire des rapports detailles. J'ai toujours 

 tenu a donner des resumes des recherches geologiques de mon 

 frere a fin que l'on put se rendre compte de la succession des 

 faunes que je decrivais; mais jeVai pas eu l'intention, et je n'en 

 avais pas non plus l'obligation, de rediger un guide avec les 

 instructions necessaires pour la recolto de fossiles." 



I think those who are acquainted with me or my work will 

 grant that I am fairly competent, as a collector of vertebrate and 

 other fossils, and not one of the many who have applied to me in 

 years past for localities will say that I did not at all times give 

 them free and full information, nor in doing so have I ever con- 

 sidered that I was acting as a guide. I had no idea, when, on my 

 first visit to Dr. Ameghino, he refrained from indicating to me on 

 a map spread before him the location and distribution of his 

 Pyrotherium beds, that he entertained the really childish ideas 

 which seem to have inspired the lines quoted above, or I should 

 never have urged his brother Charles when we were together at 

 Santa Cruz in the winter of 1898, to join me in an expedition the 

 following season to re-examine together, the different Tertiary 

 and Cretaceous horizons of Patagonia. Dr. Ameghino's remarks, 

 just quoted, fully explain to me the reason why bis brother, after 

 fully agreeing with me as to the desirability of such a joint 

 expedition and setting a time and place for our meeting the fol- 

 lowing spring to undertake the same, shortly after his return to 

 La Plata wrote me that it would be impossible for him to keep 

 the engagement, and that I must not wait for him to join me. 



Since on page 1 8 of his paper Dr. Ameghino attacks my integ- 

 rity and seems to infer that I have not acted in good faith in 

 quoting the remarks of his brother relating to the manner in 

 which he (Charles) had really found the mammalian and dino- 

 saurian faunas of the Pyrotherium and Guaranitic beds, I hope I 

 may be pardoned for a few brief remarks in defense of my posi- 

 tion. After quoting me at some length Dr. Ameghino continues 

 as follows: "Je repousse cette forme de discussion que, et j'en 

 demande pardon a M. Hatcher, ne me parait pas trop correcte; il 

 a supris la bonne foi de mon frere en lui raccontant que j'ai dit, 

 ce qu'en verite je n'ai jamais dit. C'est tout clair: il a demande 

 a Charles s'il avait trouve des debris de mammiferes associes a 

 ceux de Dinosauriens, et il lui repondit, non. Si en place de cela, 

 il lui aurait demande s'il avait trouve des debris de mammiferes 

 dans la meme formation qui contient des os de Dinosauriens, cer- 

 tainement il lui aurait repondu, oui. Pourrait-il M. Hatcher 

 m'indiquer, ou, dans quel ouvrage, et a quelle page j'ai dit que C.
