of about equal extent, is ready for the printer. This formi- 
dable treatise is entitled “ Man’s Record of his own Exist- 
ence.” Its character is indicated in the brief introductory 
sentences : — 
“In the distribution of species over the globe, the order of 
Nature has been obscured through the interference of man. 
He has transported animals and plants to countries where 
they were previously unknown ; extirpating the forest and 
cultivating the soil, until at length the face of the globe itself 
is changed. To ascertain the amount of this interference, 
displaced species must be distinguished, and traced each: to 
its original home. Detached observations have already been 
given in the twenty-first and ‘succeeding chapters of my 
‘Races of Man’; but when such observations are extended 
to all parts of the globe, the accumulated facts require some 
plan of arrangement. A list will naturally assume the 
chronological order, beginning with Egypt, the country that 
contains the earliest records of the human family, and reced-

Then, starting with “4713 B. C.,” and “4491 B. C., be- 
ginning of the first Great Year in the Egyptian reckoning,”

“Chronological Arrangement of Accompanying Animals and 
Plants,” first treats of the vegetables and animals mentioned 
in the book of Genesis, and of the “* Commencement of Be- 
douin or Nomadic Life in the Desert ;” passes to the ‘ Colo- 
nization of Egypt,” and to critical notices (philological and 
natural-historical) of its plants and animals, as well their ear- 
liest mention as their latest known migrations ; reaches the 
beginning of the Christian era at about the 470th page ; and 
so proceeds, till our wonder at the patience and the erudition 
of the writer passes all bounds. We are ready to agree with 
a biographer who declares that our associate was “a living 
encyclopedia of knowledge,” — that there never was a natu- 
ralist “who had made more extended and minute original 
explorations ;”’ and we fully agree that “no one ever had less 
a passion or a gift for display ;” “that he was engaged dur- 
ing a long life in the profoundest studies, asking neither fame
