CHLAMYDOMONAS AND HAEMATOCOCCUS 269 
of, whereof most had the outermost part of their bodies a 
pale green, and the middle of the body quite red.’ 
On the 15th and 29th of September, on the 13th and 
27th of October, on the 25th of November, and the 9th of 
December, I continued my observations aforementioned ; 
steeping the said stuff* both in new-fallen rain, that was 
collected in an East-Indian porcelain dish, and in boiled 
and ordinary rain-water: whereof I kept notes. But as 
the upshot was always one and the same, I discarded 
these notes: and I will only say that, on the day last 
mentioned, I put some boiled water, when it had got 
nearly cold, with a little of the oft aforementioned 
dirty stuff, into a glass tube that was sealed off at one 
end, and stopt with a cork at the other, and carried it 
about in my pocket: and I found some hours afterwards 
that not only the big animalcules* . . . were swimming 
in the water, but also many others so small, that they 
looked through the microscope no bigger than a dot, such 
as you might make with a pen. And when I had carried 
this glass tube in my pocket for eight days, these last- 
mentioned animalcules were so increased that there were 
some thousands of them, both fixt on the glass and 
a-swimming in the little quantity of water. 
On the 8th of February,’ when the oft-mentioned stuff 
had lain for a few days more than five months upon 
a clean white paper in my closet, I put a little of it intoa 
clean glass tube, and poured boiled rain-water, after it 
had cooled, upon it: and after the space of about halt 
an hour, I already found one animalcule swimming about 
in the water, and many others that remained still rounded 
up; and three hours later I saw various others of this 
kind, and some small ones of a different make.”
