Correspondence from Canadian geologist Sir John William Dawson (1820-1899) to H.A. Morrell, of Maine, dated from 1869 to 1876. Letters respond to inquiries from Morrell regarding identification of fossils and the sale of fossil specimens. Morrell sent Dawson drawings, impressions, and original specimens, about which Dawson offered his opinions and sometimes sought for his own collection. In 1876, he writes about his displeasure with English biologist Thomas Henry Huxley (1825-1895), who "has had since 1870 a large part of my most valuble specimens, under the pretext of comparing them, and working up some general account of Carboniferous reptiles; but he has published nothing, and though I have written things, and have caused several friends to call on him, I can get no satisfaction."
