ERRATUM. 



PAGE 21. For " The granules stream in one direction ; then 

 pause, from sixty to ninety seconds (in the case of healthy 

 plasinodia) " ; read, " The granules stream in one direction 

 from sixty to ninety seconds (in the case of healthy plasniodia), 

 then pause." 



NOTE. 



The quotation on the Title Page we have attributed to Pliny 

 in his " Natural History," on the authority of Wordsworth in 

 his heading to the Vernal Ode. We have not succeeded in 

 finding it in Pliny himself, but our search has not been 

 exhaustive.
