before : They all went on nearly in the fame Man- 
ner, and all fliewed the new Arms on their Tail-parrs 
on the fame Friday the 1 8th 5 but I muft alfo take 
Notice, that Thurfday laft the 17th was a fine warm 
Day, to which I impute it, that the Infcfts cut on Sun- 
day were juft as forward as that cut on the Day 
before. One other of the Tail-pieces of thefe alfo 
put forth a young one, during the time that it lay 
without a Head. All thefe Four laft-mentioned had 
eat about 3 6 Hours before they underwent the 
Operation. 
On Tuefday the 15 th Inftant, I took a Toly pus 
that had eat a Worm on the Saturday , and, placing 
it as before in the Hollow of my Left Hand, I at> 
tempted, when it was moft contra&ed, to divide it 
longitudinally $ but my Scifiars not being very good, 
I mifsd my Stroke, was forced to give a Second, and 
even then divided it very unequally ; the Head was 
however fplit, and of Ten Horns that it had. Six 
came off with the lefler Piece that was only a Slip of 
the Body, and the Four others remained with the 
reft, which was at leaft Seven-eighths of that Body. 
I had very fmall Expectation from this Experiment, I 
neverthelefs put both the Pieces with fome Water 
into a Phial 5 and both this Day in the Afternoon 
and the next, I faw both Parts playing their Arms. 
On Thurfday the 17th, in the Forenoon, perceiving 
both thefe Parts to move their Horns pretty briskly^ 
I gave to each a Piece of a Worm: Each readily 
feized it, eat it, and kept it as ufual j and the fame 
Day in the Afternoon, I took Notice, that a little 
one was putting out from the Side of the- larger 
Piece. 0
