teristic smell of the sulphochloride of carbon was observed 
This was further recognised by its deportment with alkalies, 
and after its removal from the liquid, the tetrachloride of 
carbon was easily recognised by its peculiar sweet smell 
strongly reminding one of the smell of primrose leaves. 
A weighed portion of the trichloride was heated with the 
requisite amount of carbon bisulphide to convert it into the 
above products, when it was found there was neither an ex- 
cess of carbon bisulphide nor of the trichloride present. The 
liquid was allowed to cool, and when all the iodine had crys- 
tallized out, it was passed through a small filter of asbestos 
and washed with a few drops of carbon tetrachloride. The 
iodine on the filter was estimated and gave only a little 
under the required amount. The filtrate was then treated 
with caustic potash, and the separated carbon tetrachloride 
weighed after transference to a tared bulb. The sulphu\* in 
the liquid, left after removal of the tetrachloride of carbon, 
was oxidised by means of potassium chlorate and strong 
nitric acid, and estimated as barium sulphate. 
The following table gives the figures which were obtained 
on working with 10 grammes of iodine trichloride, and also 
those deduced from the above equation : —

“Note by A. W. Waters to his paper on the Bryozoa, 
page 125.” 
At the time I wrote my paper I was unable to consult 
Thompson’s “ Zoological Researches,” but upon referring in 
London I find that as the quotation given relates to the 
Flustracese it would have been better to have given the 
following from page 97 : “The other species of Sertularia in 
which the animals have been determined to be Polyzose.” 
Also on page 132 of my paper read for “coenosare” — 
“endosare,” which term is used by Joliet for the first time.
