Gatterer supposes different Chains, Tuning in different latitudes, to cross at intervals forming a kind of net-work. According to Pallas, they radiate from a common centre. His anonymous critic takes two principal Chains parallel with the equator, the one about 50 north latitude, the other about 25 south latitude, and supposes branches to be sent off from each of these towards the equator, and towards the poles. Our knowledge upon this subject, confined and inaccurate as it is, enables us to pronounce that all these systems are erroneous. Some modern writers have been disposed to confound chains of mountains with waterheads, and imagine that a line connecting the sources of rivers all over the globe must faithfully represent the line of greatest elevation.
