Mr. Baker says that Mr. Arderon was also the first to find the 
very beautiful zoophyte which Mr. Trembly afterwards called the 
Polype a panache. “ I was first informed of this creature by 
my industrious friend Mr. William Arderon towards the end of 
the year 1743, as his letters show, and in the year 1744 it was 
taken notice of by Mr. Trembly, who gave it in his Memoires. 
The name of the Polype a Panache or plumed Polype. My 
Iriend who discovered it called it the Bell flower Animal.”* 
I have an original sketch of this animal made by Mr. Arderon ; 
he says he found it in a ditch near Spring Gardens in Norwich, 
[The locality of these Gardens had long puzzled me ; my friend 
Mr. Knights, however, informed me that “ The Spring Gardens, 
in Norwich,” were by the river-side at the bottom of Rose Lane, 
occupying the site upon which now stands oilcake mills, timber 
yards, rows of houses, and boat yards.t] 
The insect described below was one of the sociable mites, 
probably Tetranychus salicis or willow mite. 
Insects on Willows. 
“ On the 12th of August (1749), in the evening I happened to go 
out into my garden, in the passage to which stand some willow 
trees. Having a candle in my hand, I observed the barks of these 
Willows appeared as if they had been covered with a thin coat of 
Ice, but coming nearer I found it was with something not much 
unlike a spider’s web, only this reflected the light prodigiously. 
The day following I went to examine it again, and I saw myriads 
of little insects running upon the glistening webs which surrounded 
every part and branch of these trees, they were in continual 
motion, running backwards and forwards, they -were shaped exactly 
like a common mite, but their hairs I think, were longer, their 
coats were of an orange colour, but curiously varigated with black 
which gave them a great resemblance to tortoiseshell. They little 
exceeded a common mite in magnitude. Under these webs the 
whole back of the trees and every branch of them were covered with 
* This animal is the Alcyonella stagnorum, of recent observers. It used 
to be found in the swan pond at St. Helen’s Hospital. 
t There was also a Spring Gardens on Mousekold.
