The Apostle of Evolution. 149 



urging you not to draw money from this side at the present 

 ruinous condition of exchange. 



I know you view the state of affairs here with great 

 apprehension, and it is not surprising that you should ; but 

 we are NOT going to the devil. " My word for it," if you 

 want a guarantee ! I believe that any amount you may 

 leave in the hands of D. Appleton & Co. will be just as 

 safe as if in the hands of the best London publishing house 

 you could name. It would be far better to let it lie idle in 

 their hands a considerable time than to draw it before ex- 

 change finds its equilibrium; or, better yet, you can have it 

 deposited in a savings bank, where it will draw six per cent 

 interest. I believe those institutions are entirely trust- 

 worthy. I trust them myself without hesitation. I hope 

 you will trust us for the present, and when the amount of 

 indebtedness becomes considerable, if exchange is still high, 

 it would be better to invest it in some form of produce 

 consigned to a London or Liverpool commission house. 

 Excuse me for interfering with this element of your busi- 

 ness. I have done it in pure friendliness, and I shall be 

 grieved and disheartened were you again to lose as you 

 sacrificed last fall. 



I received the advance sheets of Prof. Tyndall's book 

 on Heat, and I beg of you to express to him my sincere 

 thanks for the kindness. The Appletons will issue it at the 

 earliest moment, the cuts being already nearly all re-en- 

 graved. It is a very fascinating and altogether remarkable 

 book, and it will be a pure pleasure for me to work for its 

 circulation. It cannot fail, I think, to have a good sale.
