INTRODUCTION. 



Garter has gained by his researches on Sponges and Foramini- 

 fera," and "whose additions to our knowledge of the minute 

 structure of certain types of Foraminifera are estimated by no 

 one more highly than by " himself, Dr. Carpenter enters into a 

 long statement highly irrelevant in many respects, and contain- 

 ing much that is given in his previously published papers.

The writer reiterates his former statement that the " cha- 

 racter " of the aciculae of the " proper wall " of " Eozoon " is 

 " utterly incompatible with foraminiferal structure." 



Latest Observations on Eozoon Canadense by Prof. Max 1874. 



Schultze. (A letter to the Editors of the 'Annals and 



Magazine of Natural History/ by Arthur E. Barker, 



Surgeon to the City-of-Dublin Hospital, and Demonstrator

This communication contains a copy of a letter from Prof. 



Max Schultze to Mr. Barker. The former, acknowledging the 



receipt from the latter of a copy of our paper published in the 



f Proceedings of the Royal Irish Academy/ July 1869, states 



that he ' ( agrees with " us " in many important points, supported 



by my own investigations on Bozoon Canadense/' and that our 



tl treatise has made a very great impression upon " him. He 



begs Mr. Barker to obtain some specimens of Connemara ophite, 



l< and to tell Messrs. King and Rowney that, with respect 



to the ' proper wall' of Carpenter, I am entirely of their 



opinion that it is of inorganic origin." Mr. Barker concludes : 



" I may state that, through the kindness of Dr. King, I was 



enabled to send Professor Schultze some beautiful specimens 



of the stones he desired, and was expecting from him a letter of 



acknowledgment when I received the sad news of his death."
