382 LOUIS AGASSIZ. 



time to read and profit by your introduction to 

 the Old Red. I am inclined to sing hymns of 

 praise to the Hyperboreans who have helped 

 you in this admirable work. What you say 

 of the specific difference in vertical line and 

 of the increased number of biological epochs 

 is full of interest and wisdom. No wonder 

 you rebel against the idea that the Baltic con- 

 tains microscopic animals identical with those 

 of the chalk ! I foresee, however, a new battle 

 of Waterloo between you and my friend Eh- 

 renberg, who accompanied me lately, just after 

 the Victoria festivals, to the volcanoes of the 

 Eifel with Dechen. Not an inch of ground 

 without infusoria in those regions ! For Heav- 

 en's sake do not meddle with the infusoria 

 before you have seen the Canada Lakes and 

 completed your journey. Defer them till 

 some more tranquil period of your life. . . . 

 I must close my letter with the hope that you 

 will never doubt my warm affection. Assur- 

 edly I shall find no fault with any course of 

 lectures you may give in the new world, nor 

 do I see the least objection to giving them for 

 money. You can thus propagate your favor- 

 ite views and spread useful knowledge, while 

 at the same time you will, by most honorable 

 and praiseworthy means, provide additional 

 funds for your traveling expenses. . . .
