authors criticised. Nor is this to be wondered at, for if Dr. 

 Ameghino is so unfamiliar with his own published statements 

 as to make the errors cited above, he can scarcely be expected to 

 familiarize himself with the work of others. He affirms that I 

 have never seen the Pyrotherium beds, and reproaches me, there- 

 fore, for having said anything about them, notwithstanding the 

 fact that his brother Charles distinctly stated to me that certain 

 deposits on the upper Rio Shehuen, with which I am acquainted, 

 pertain to these beds. Not having myself found any characteris- 

 tic fossils in these deposits, I relied entirely upon the determina- 

 tions of Charles Ameghino as to their identity, and I still have 

 no good reason for doubting the correctness of his determinations, 

 but every reason for doubting the age ascribed to them by Dr. 

 Florentino Ameghino. 



Again, in speaking of the lakes of Patagonia, Dr. Ameghino 

 reproaches me, and not without some reason, for venturing to 

 say anything concerning Lakes Colhue and Musters, neither of 

 which I have ever seen. This fact, one would infer, is in Dr. 

 Ameghino's opinion sufficient reason why I should have remained 

 silent. Indeed I am half inclined to a<n*ee with Dr. Ameghino 

 in. this matter, and I only wonder why it has never occurred to 

 him to apply the same rule of stricture to his own publications, 

 for I fully realize the confusion that might thereby have been 

 avoided concerning the geology of Patagonia, a country he has 

 never visited. J. b. hatcher. 



6. Catalogue of Meteorites in the Yienna Museum. — Prof. 

 F. Berwerth has published (Annalen des k. k. naturhistorischen 

 Hofmuseums, Wien, Bd. xviii) a catalogue, with two appendices, 

 of the meteorites in the Vienna Museum at the close of October, 

 1902. The catalogue shows that this collection still retains its 

 rank as the largest in the world, the total number of falls repre- 

 sented being 560, and the total weight of cosmic matter exhibited 

 3,313 kilograms, of which 2,553 kilograms are meteoric irons, 

 122 kilograms ironstones, and 637 kilograms stones. 



In the first part of the catalogue the falls represented in the 

 Vienna collection are grouped chronologically under the separate 

 divisions of irons, iron-stones and stones. Relegation of Santa 

 Catarina to the group of pseudo-meteorites is a noteworthy 

 change here and one with which most students of meteorites will 

 agree. On the other hand, the grouping of the meteorites of 

 Prairie Dog Creek, Jerome, Kansada and Ness County under the 

 one head of Prairie Dog Creek, is not likely to meet with unqual- 

 ified approval. 



The first appendix gives an alphabetically arranged list of all 

 known meteorites, with their classification, date of fall or find, 

 and latitude and longitude of the locality from which each was 

 obtained. It is to be regretted that the latter feature seems 

 somewhat lacking in accuracy, errors of several degrees being 

 observable in more than one case. In choosing names for the 

 falls, Prof. Berwerth has followed in general the plan of giving
