the composition of those which nature produces in a compound state ; and the application of the whole to the arts and manufactures . Some branches of philosophy , again , are chiefly useful and interesting to particular classes , as surgeons and physicians . Others are easily understood

by a knowledge of the principles of Mechanics and Chemistry , of which they are applications and examples ; as those which teach the structure of the Earth and the changes it has undergone ; the motions of the muscles , and the structure

of the parts of Animals ; the qualities of animal and vegetable substances ; and that department of Agriculture which treats of soils , manure , and machinery . Other branches are only collections of facts , highly curious and useful indeed , but

; Glad Hope and Trust sublime , Affection ' s grace and glow , Its glamour and its flow , Its countless pleasant ways , Die with our dying clays . How strange to know and feel

The truths our hearts conceal ; The things we love the most , Our earthly pride and boast , The dearest things of earth , Fade often in their birth .

'Midst heavy falling tears , We miss the love of years , We miss the trust which never waned , We miss the wit which never pained , We miss the grave and classic brow ,

Sadly , sorely , truly , now ! But Hope is whispering still , Through the hours of human ill , Through joys and heavy cares , Through trouble resignation bears ,

' ¦ Believe that all is for the best ; The weary one ' s at rest ! " NEMO .
