"[illegible] Martin today of Brilliston party. He tells me he found cutaceous birds this Spring. Brilliston is to have just pick'd and the Martin is to write us. Our cynicist slot is in Burlington. There is every appearance that all the beds of the Freyge Out Hills are of very shallow water since many of the beds are ripple marked. Such have been seen in the Red beds where the limestone is also rippled. Same have been seen in the Devonian layers. The transition from the marine fauna to fresh water fauna is a gradual one and is not dissimilar for these fishes. I cannot believe there was a lake but rather an arm of the sea that was filled up and became a fresh water moran due to stream beds flowing from a highland. With the introduction of the Dalotus then are a physical change and introduction of coral angletion which precedes through to the begining of Laramian time when it was closed off of this region.
