ca,” with drawings, illustrating the following species, namely, Phyllogonium Norvegicum, Brid. (recently detected in Ohio); Fissidens minutulus, Sulliv.; F. exiguus, Sulliv.; Schistidium serratum, Hook. & Wils. ; Aneura sessilis, Sulliv.; Marchantia disjuncta, Sulliv.; Notothylas valvata and N. orbicularis, Sulliv.

Dr. Holmes, from the committee appointed at the meeting in March to report upon the case of Henry Safford, the young Vermont mathematician, stated, that, at the request of Professor Peirce, the drawing up of a full report had been deferred until the arrival of the boy in this vicinity, where he is expected to reside. Some interesting statements were made by Professor Peirce, from which it would appear that the mere calculating faculty is not by any means as remarkable in him as it was in Zerah Colburn, but that it is rather incidental, as a part of extraordinary reflective powers.

S. P. Andrews, Esq., of Boston, and George Engelmann, M. D., of St. Louis, Missouri, were elected Fellows of the Academy.

The following were elected Foreign Honorary Members of the Academy, viz. :

Prof. Louis Agassiz, of Neuchatel, Switzerland.
M. Edouard de Verneuil, of Paris.

M. Joseph Decaisne, Professor at the Jardin des Plantes, Paris.
