have every appearance of animalcula. Several of my microscopic 

 friends who have seen them are of the same opinion, particularly the 

 above gentleman, who has paid great attention to microscopic pur- 

 suits. Whether they are living animalcula or not, I am at a loss to 

 determine, and must leave it for the investigation of our microscopic 

 friends. The readiest way of examining them is as follows :— Take 

 a single scale from any fish (say a fresh herring) ; put it on a flat 

 piece of glass, and cover it with a drop of pure water; press the scale 

 to make it lie flat on the glass ; place it under the microscope with 

 a piece of black paper, or the black ivory stage-piece of the micro- 

 scope, as it must be viewed as a perfect opake object, or the effect is 

 not seen : by means of a condenser throw a strong light upon it from 

 a lamp or candle j and you will observe a multitude of minute bodies 

 in motion on the scale : but they are much more visible in that part 

 of the drop of water which the scale does not occupy, forming a most 

 beautiful and interesting microscopic object. 



LUNAR OCCULTATIONS FOR OCTOBER AND NOVEMBER. 



Occultations of fixed Stars by the Moon, visible at Greenwich in the 

 Year 1833. Computed by Thomas Maclear, Esq.; and circu- 

 lated by the Astronomical Society. 



%* The angles are reckonedyVom the northernmost point, and also from the ver- 

 tex, towards the right hand, round the circumference of the Moon's image, 

 as exhibited in an inverting telescope. 



An Asterisk (*) annexed to the time of the phenomenon is intended to denote 

 that the Star is on, or near to, the meridian, at that time.
