Excerpt from Proceedings of the California Academy of Sciences, Vol. 1: 1888 The great serpentine belt crossing the North Fork of the American River, above Dutch Flat, contains several deposits of chromite, some of which are worked on a small scale. While examining the ore from one of these occurrences - Green Valley, in the canon of the American River below Towle's on the Central Pacific Railroad - I found coatings, of a scaly mineral of a beautiful peach blossom color, together with smaller pieces of the same mineral in massive state. The substance proved to be a chlorite, and is most closely allied to that variety of clinochlore to which Kotscharow has given the rather harshly sounding name of kotschubeite.

Excerpt from Proceedings of California Academy of Sciences, Vol. 1 Early in 1905 the California Academy of Sciences decided to send an expedition to the Galapagos Islands. The general purpose was to explore this group more thoroughly than the opportunities of previous investigators had permitted, and to secure large collections of the plants, mollusks, insects, birds, mammals, and reptiles in the hope of throwing more definite light upon the origin of the archipelago. Particularly, it was determined to study the geology of the islands, to make a very careful search for fossils, and to spare no effort to secure specimens or remains of those races of the gigantic land tortoises which long had been thought extinct.

Excerpt from Proceedings of the California Academy of Natural Sciences, 1858-1862, Vol. 2 The question is often mooted in our courts, whether the age of a tree can be determined with any degree of accuracy by referring to the rings or growth of the wood. F rom the observations I have made during a period of twenty years, or more, I have long since been convinced, that as a. General thing each ring or growth of the timber represented a year of the existence of the tree. The specimen presented this evening, goes to substantiate more clearly, my previous conclusions.

Excerpt from Proceedings of the California Academy of Sciences, Vol. 1: Botany; 1897-1900 Schumann (1892) has also investigated the structure of Naz'as, but, like his predecessors, pays no attention to the minute structure of the floral parts. His results agree in the main with those of Magnus, but he does not agree with the latter in considering the envelope surrounding the ovule as a peculiar structure, but, in common with other botanists, regards it as a carpel, a view which Magnus vigorously opposes.
