ROSA ON THE REVISION OF THE LUMBRICIDI. 
Rev. HILDERIC FRIEND, F.L.S., 
Author of ‘ Flowers and Flower-Lore, Cockermouth. 
It is now exactly a decade since Dr. Daniel Rosa, of Turin, first 
appeared as the champion of the despised earthworm. Four years 
after the publication of Darwin’s memorable volume on ‘ Vegetable 
Mould,’ Rosa gave a description of two new species of Lumbricus 
in the pages of ‘Atti Acad. Sc. Torino,’ vol. xviii. (1882). This 
was followed two years later (1884) by his pamphlet entitled, 
_ *I Lumbricidi del Piemonte ’—a work which at once marked out its 
author as a most accurate, painstaking, and reliable authority on this 
hitherto neglected subject. Since then not a year has passed but 
some further original communication from his pen has enriched the — 
annals of science. This decade of persistent and wide-reaching 
investigation has at last yielded its ripe fruit, and we now have 
before us a handsome monograph of upwards of 80 pages folio, 
devoted to a ‘ Revisione dei Lumbricidi.’ (Torino. Carlo Clausen ;

Dr. Rosa, like all the Continental scientists with whom we have 
_ had occasion to correspond, is genial and courteous in his bearing, — 
_ and loses no opportunity to give the credit due to others for the | 
_ work they have done. His newest work contains a most valuable 
_ and elaborate Bibliography, in which we find the names of English, 
oS French, German, American, Swedish, Italian, Russian, Australian, _ 
_ and other authors faithfully chronicled in connection with upwards 
of one hundred articles and monographs, ranging from the days of — - 
-  Linneus (1767) to the present time. The plan is to give the 
‘Two charts at the end present, in a new and striking form, the —
