82 or nearly 5" by chronometer, exists between the longitudinal positions of Mount Hamilton, as determined from the two surveys; as the discrepancy is one of absolute distance, it does not affect the value of either survey. The desirability of having a check on the chronometrical determination of the longitudes of meridians was kept in view during the survey by carrying on, with as much care as possible under the circumstances, a triangulation based on short lines. After plotting the work to the scale of one-half inch to the mile, it is satisfactory to state, considering the rugged nature of the country, that the difference between the chain and chronometrical measurements of the distance between Lindis Peak and Mount York was not appreciable; the meridian of Mount Nicholas when brought to the same test, shows a difference of 2 by chronometer.

To check the altitudes, several peaks were determined, both from the data of Mount Pisa and from the data of the Bluff. The nearest agreement of the two determinations was that of Earnslaw, the difference being only 2 feet. The greatest disparity was in the two determinations of Mount Nicholas, the difference being 107 feet. The angular measurements of the survey were all made (with the exception of the astronomical observations), by a 4-inch Everest theodolite. Throughout the survey, an equal attention was given to the details of each district; so that unnecessary minuteness was not obtained in one part at the expense of vagueness in another. 

V. — An Exploration up the Moisie River, to the Edge of the Table-land of the Labrador Peninsula. By Author:Henry Youle Hind,,, Trinity College, Toronto. Read, January 25, 1864.

Moisie River has for centuries been the canoe-route of the Montagnais tribe of Indians from the Gulf of St. Lawrence to the interior of the Labrador peninsula; and within the last fifteen years this river has formed the route by which a few families of the Nasquapee Indians, whose hunting-grounds lie on the table-land, have reached the gulf. The mouth of the Moisie is about 18 miles east of the well-known Bay of Seven Islands; and, as the general direction of its course is very nearly due north, it forms, probably, the shortest route by which the table-land can be reached from this part of the gulf. It has also this advantage, that the north-east branch is separated by a very low water-parting from the head-waters of the Ashwanipi, or Hamilton River, the great river of the table-land, which, after a course of about 400 miles, empties into Hamilton Inlet, and forms an inland canoe-route, in
