600 THE AMERICAN NATURALIST. 
In the same year I discussed the subject in connection with the 
Umbelliferz,! enumerating the visits of forty species of beetles to 
flowers of Pastinaca, which is nearly twice as many as Müller ever 
found on any umbellifer. In the Botanical Gazette, Vol. XXII, 
p- 169, 1896, I have cited the statements of Bonnier and Schulz. 
Finally, Knuth,? in a volume devoted to the general principles of 
anthoecology, abandons Miiller’s view with the statement that Miller 
himself and Loew had made observations which did not support it. 
He does not mention the observations of Bonnier, Schulz, or mine; 
but, of course, when a man feels at liberty to use the literature in 
any way he likes, he can record old things as new, and give credit 
in any way that suits his fancy. These references ought to be 
enough to dispose of a proposition which was never supported by a 
reasonable presumption. Chants Rostetsü
