those he had seen had the soft disk supported by the pali. He 
was then made aware that the supposition did not come within 
the scope of the word conjecture, and there was no remon- 
strance whatever on his part, as Prof. Lindstrém thinks. The 
so-called supposition was not mine, but that of a man whose 
admirable and extensive original researches led him beyond 
the troubles of criticism. Jules Haime’s essay on the soft 
parts of Cladocora cespitosa* is one of the most interesting 
and important of his works, and is of great value because he 
described the soft structures in their natural condition and not 
after altering them by reagents. It was necessary that I 
should abstract this essay in my introduction to the ‘ Sup- 
plement to the British Fossil Corals,” Paleontographical 
Society, 1866. ‘The translation of the part of the sentence, 
“coincide avec la présence des palis situés au dessous et en 
dedans de ces tentacules,”’ although placed between inverted 
commas, was mistaken by my friend as my own opinion and 
the result of my own work. 
There was no supposition, but a definite statement of a fact 
by a naturalist who was as well able to judge the truth as 
any subsequent investigators. 
Whilst I was preparing the monograph just alluded to, Mr. 
Peach was good enough to watch and draw some specimens 
of Caryophyllia clavus, var. borealis, and to send me his 
finished delineations and descriptions. The lithographs on 
plate ii. Monogr. Brit. Foss. Corals, pt. 1. 1866, figs. 9-20, 
are correct reproductions of nature. He was convinced, as I 
was and still am, that the inner row of tentacles of figs. 9 and 
11 relate to the pali in ‘the manner seen by Jules Haime in 
Cladocora.
