292 THE ' EFFECTS OF CROSS- [1876. 



" I worked last summer hard at Drosera, but could not 

 finish till I got fresh plants, and consequently took up the

 this, and get it published ; but then I will resume my beloved 

 Drosera, and I heartily apologise for having sent the precious 

 little things even for a moment to the dogs."

 will, therefore, rapidly receive the remainder. The book is
