the moon,--
So life's vast tide forever comes and goes,
Unchecked, resistless, as it ebbs and flows.

Hardest of all, when Art has done her best,
To find the cuckoo brooding in her nest;
The shrewd adventurer, fresh from parts unknown,
Kills off the patients Science thought her own;
Towns from a nostrum-vender get their name,
Fences and walls the cure-all drug proclaim,
Plasters and pads the willing world beguile,
Fair Lydia greets us with astringent smile,
Munchausen's fellow-countryman unlocks
His new Pandora's globule-holding box,
And as King George inquired, with puzzled grin,
"How--how the devil get the apple in?"
So we ask how,--with wonder-opening eyes,--
Such pygmy pills can hold such giant lies!

Yes, sharp the trials, stern the daily tasks
That suffering Nature from her servant asks;
His the kind office dainty menials scorn,
His path how hard,--at every step a thorn!
What does his saddening, restless slavery buy?
What save a right to live, a chance to die,--
To live companion of disease and pain,
To die by poisoned shafts untimely slain?

Answer from hoary eld, majestic shades,--
From Memphian courts, from Delphic colonnades,
Speak in the tones that Persia's despot heard
When nations treasured every golden word
The wandering echoes wafted o'er the seas,
From the far isle that held Hippocrates;
And thou, best gift that Pergamus could send
Imperial Rome, her noblest Caesar's friend,
Master of masters, whose unchallenged sway
Not bold Vesalius dared to disobey;
Ye who while prophets dreamed of dawning times
Taught your rude lessons in Salerno's rhymes,
And ye, the nearer sires, to whom we owe
The better share of all the best we know,
In every land an ever-growing train,
Since wakening Science broke her rusted chain,--
Speak from the past, and say what prize was sent
To crown the toiling years so freely spent!

List while they speak:
In life's uneven road
Our willing hands have eased our brothers' load;
One forehead smoothed, one pang of torture less,
One peaceful hour a sufferer's couch to bless,
The smile brought back to fever's parching lips,
The light restored to reason in eclipse,
Life's treasure rescued like a burning brand
Snatched from the dread destroyer's wasteful hand;
Such were our simple records day by day,
For gains like these we wore our lives away.
In toilsome paths our daily bread we sought,
But bread from heaven attending angels brought;
Pain was our tea
