190 H. HENSOLDT ON CAVITIES IN METEORITES. 



them. He was kind enough to submit them to my inspection, and 

 I certainly observed the phenomenon in four out of five sections, 

 one being from a fragment of the well-known meteorite of Pul- 

 tusk. I do not know in how far the meteoric character of these 

 sections was established, but besides having been procured from es- 

 teemed and well-known mounters, they presented the appearance of 

 genuine meteorites. 



In conclusion I will also draw attention to the fact that, when 

 Dr. Hahn, not two years ago, made known his discovery of organic 

 remains in material of meteoric origin, he was fiercely attacked, 

 and most of the critics, especially in this country, derided the very 

 possibility of such a discovery. Now, after prolonged and careful 

 investigation, the meteoric character of the substance has been 

 established, and the truth of the other assertions is all but generally 

 acknowledged.
