sight, in figures, magnitudes, motions, colours : all dem 

 onstrations of shadows. 1 We find also divers means, 

 yet unknown to you, of producing of light originally 

 from divers bodies. We procure means of seeing ob 

 jects afar off; as in the heaven and remote places ; and 

 represent things near as afar off, and things afar off as 

 near ; making feigned distances. We have also helps 

 for the sight, far above spectacles and glasses in use. 2 

 We have also glasses and means 3 to see small and mi 

 nute bodies perfectly and distinctly ; as the shapes and 

 colours of small flies and worms, grains and flaws in 

 gems, which cannot otherwise be seen ; observations 

 in urine 4 and blood, not otherwise to be seen. 5 We 

 make artificial rain-bows, halos, and circles about light. 6 

 We represent also all manner of reflexions, refractions, 

 and multiplications of visual beams of objects. 



&quot; We have also precious stones of all kinds, many 

 of them of great beauty, and to you unknown ; crys

 besides those of which you make glass. Also a num-

 by an apparatus in which the amount of sugar present in it is to be meas

6 Nothing that has been accomplished with the microscope would have 

 interested Bacon more than the discoveries of Schleiden and Schwann, 

 because nothing has brought us so near the latens processus by which the 

 tissues of organic life are formed. Jt is remarkable,that when Schleiden 

 had as he conceived destroyed the analogy between the developments of 

 vegetable and animal life, by showing that all vegetable tissues are de 

 veloped by cells, Schwann should have re-established it more clearly than 

 before by showing that this is true of all animal tissues also. R. L. E.
