is at least 10, and consequently a drop is a 1000 times larger than that sand, 

 and therefore 1,000,000 living creatures in one drop of water. In which com- 

 putation I rather lessen than heighten the number. 



These, Sir, I thought good to add to the observations I have made, and 

 showed to others, with the applause of the beholders. The rest, and the make 

 of my microscopes I cannot yet communicate. After I had sent away my for- 

 mer letter, I gave not over observing the animalcula in water ; examining also 

 distilled and boiled waters. Last winter, when the severe cold had killed the 

 little creatures, observing the water thawed by the warmth of the room in which 

 it had stood for a whole day with a fire in it, I found after 24 hours were 

 elapsed, and another time after 17 hours were passed, that some living animals 

 appeared again in that water.

An Account of Observations made for several Years together^ concerning three 

 New Stars, one in the TVhales Neck, the other two near the Head and Breast 

 of the Swan. By M. Hevelius. N° 134, p. 853. Translated from the Latin^ 



It is well known that the new star in the neck of the Whale has been con- 

 tinually observed, from the year l638 to the year 1662, and in the same place 

 in the heavens ; but not always of the same magnitude, nor shining with the 

 same lustre ; but in some years disappearing, and again shining out, sometimes 

 sooner, sometimes later, without observing any certain periods of time : as 

 fully appears in the short history of that wonderful star, published in 1662, with 

 my account of Mercury seen in the sun, p. l64. But in the subsequent years, 

 especially from l665 to the present time, that star has not been so diligently 

 explored. And therefore, for continuing that short history, I have added the 

 following table, exhibiting the appearances and returns of that star : by which 

 it may be known at once, its beginning and ending, how it has increased and 

 decreased, when it disappeared, and when it shone out again. You will there 

 see that the said new star in CoUo Ceti appeared in every year, till Oct. 1672, 

 though as it were with a different phase : but that after that it never appeared 

 again for an interval of 4 years, viz. from about Oct. 1672,' to Dec. 1676, as I 

 may say that I sought for it with watchful eyes, every time that I made observa- 

 tions in clear nights. 



Therefore, by how much the less it has been observed by the ancients, that
