On Some of the Means of Delineating Microscopic 

 Objects. By W. T. Suffolk. 



(Bead January 22nd, 1869.) 



[Abstract.] 



I HAVE been induced to bring the subject of microscopical drawing 

 before the club, principally because the idea prevails that the pro- 

 duction of representations of objects viewed under the microscope 

 is attended with unusual difficulty. Certainly, this is the case with 

 elaborate representations, especially of objects as they appear under 

 the binocular microscope. But the production of drawings, both 

 truthful and of great utility as records of observation, is by no means 

 so cUfficult as it is supposed to be. We cannot all expect to equal 

 the minutely accurate drawings and lithographs of Tuffen West, 

 the delicate representations of tissues by Dr. Beale, so ably inter- 

 preted on wood by Miss Powell, the marvellously accurate figures 

 by Richard Beck, reproduced by some talented engraver, whose 

 name is unknown to me, but whose work I none the less admire — or 

 the wood blocks engraved by our own member, Mr. Ruffle ; but I 

 think almost any microscopist might be able, with the aid of some 

 one or other of the instruments I am about to describe, to make 

 useful records of his own observations — rough, possibly in execu- 

 tion, but still much more truthful than drawiugs made by a more 

 skilful but less scientific artist. 



Photography is, under certain conditions, undoubtedly the most 

 perfect means of obtaining representations of microscopic objects ; 

 but, unfortunately, these conditions limit, to a great extent, its
