22 FLOWERS THAT NEVER FADE 



Of this first set, the larger part is still to be 

 seen in the Natural History Museum at 

 Dresden. From 1870, when he took his 

 only son, Rudolph, into partnership, he 

 began to increase his production of the 

 models of marine invertebrates that are 

 now among the most interesting treasures 

 in all the natural history museums through- 

 out the world, including the Museum of 

 Comparative Zoology at Harvard. For the 

 next sixteen years the two artists gave 

 their time exclusively to the pursuit of this 

 branch of their life-work.
