Collection and Mounting of Objects. 29 



And now, reader, for further information about 

 microscopic objects I refer you to the coloured plates 

 and the woodcuts which follow, and to my descriptions 

 of them. The plan employed in their arrangement is 

 this : we first go through a set of prepared objects, 

 which could be shown on a winter evening, or at any 

 time, and then we have an account of a summer enter- 

 tainment, with the wonders to be observed in the 

 structure of living things. 



The coloured plates are all from my drawings, 

 but for most of the illustrations of animalcules I am 

 indebted to two or three experienced microscopists, 

 as I have never systematically studied this class of 

 objects, although I have repeatedly examined all to 

 which I allude in these pages. 



For the guidance of those who prepare their own 

 microscopic objects, as all will do who possess and 

 really value a microscope, I give a list of the objects 

 in my plates which are mounted in balsam. It will be 

 understood that those not included in this list are 

 mounted in the dry method. Plate II., fig. 1, d, figs.
