The column headed " Magnet" is an attempt to distinguish the character 

 of each day, as regards the frequency or extent of '.he fluctuations of the 

 Magnetic declination, indicated by the self-registering instruments at Toronto. 

 The classification is, to some extent, arbitrary, and may require future 

 modification, but has been found tolerably definite as far as applied. It is as 

 follows: — 



(a) A marked absence of Magnetical disturbance. 



(i) Unimportant movements, not to be called disturbance. 



(c) Marked disturbance — wliellier shewn by frequency or amount of 

 deviation from the normal curve— but of no great imporlance. 



(d) A greater degree of disturbance — but not of long continuance, 

 (f) Considerable disturbance — lasting more or less the whole day. 

 (_/■) A Blaguetical disturbance of the first class. 



The day is reckoned from noon to noon. If two letters are placed, the first 

 applies to the earlier, the latter to the later part of the trace. Although the 

 Declination is particularly referre)] tn, it rarely happens that the same terms 

 are not applicable to the changes of the Horizontal Force also.

Kcm Species of Oraiiy. — At a in 



of the Academy of Sciences 



of Pbiladelpliia ou the Srd of February, a very iiiterestiug coiiinunii- 

 catiou was read from Dr. H. A. Ford, dated Glasstown, Gaboon River, 

 West Africa, respecting the characteristics of a peculiar species of 

 Oiang, tlie Troglodytes Gorilla, which appears to bave been tirst 

 noticed by Bowditch in 1817, and first described by Savage and 

 Wyraan iu 1847. 



The animal inhabits tlie range of niount;iius tluit traverses tbe intcrioi; 

 of Guinea, from the Canierooiis ou tlie north to Angola on tlie south, 

 and about 100 miles inland, tlic c.'iact limits to which it extends have 



not been very accurately determined. Formerly, the animals were 

 found only about the sources of tbe rivere, but lately they have de- 

 scended to within a few mUcs of the coast, a fact which may probably 

 iftcouut for the little that is yet known respecting tliem. 



The name given by the natives is Ngena, when ■, ouiig he is black 

 like the Troglodytes uiger, but when adult of an iron grey colour, 

 owing to the hair next tbe skin being white ; some are entirely white, 

 jjrobably tiom age. 



Tbe hair is of great length and thickness, and from this circumstance, 



together with the enonuous thickness of tbe skin, the brute appe;irs of 



. an enonuous size. Tlie specimen examined, by no moans a hirge one, 



measured three and a hall feet across the shoulders. On tlic head the
