1868 'ARTHROPODEN WERK' 439 



house nearly three months, and have been like lepers, cut off 

 from all communication with our neighbours for that time. 



We have had a great deal of anxiety, and my wife has 

 been pretty nearly worn out with nursing day and night ; 

 but by great good fortune " the happy family " has escaped 

 all permanent injury, and you might hear as much laughter 

 in the house as at Swanage. 



Will you be so kind as to thank Professor Gegenbaur 

 for a paper on the development of the vertebral column 

 of Lepidosteum I have just received from him. He has 

 been writing about the process of ossification and the 

 " deck-knochen " question, but I cannot make out exactly 

 where. Could you let me know ? 



I am anxious for the Arthropoden Werk, but I expect 

 to gasp when it comes. 



Turn to p. 380 of the new edition of our friend 

 Kolliker's Handbuch, and you will find that though a 

 view which I took of the " organon adamantinae " some 

 twelve or fourteen years ago, and which Kolliker has up 

 to this time repudiated, turns out, and is now admitted 

 by him, to be perfectly correct, yet "that I was not 

 acquainted with the facts that would justify the conclu- 

 sion." Really, if I had time I could be angry. 



Pray remember me most kindly to Haeckel, to all 

 whose enemies I wish confusion, and believe me, ever 

 yours faithfully, T. H. HUXLEY. 



P.S. I have read a hundred pages or so of Fanny 

 Lewald's 1st Bd., and am delighted with her insight into 

 child-life.

MY DEAR TYNDALL All I can say is, I am heartily 

 sorry. 



If you feel that your lectures here interfere with your
