 velopment of the plates in an inn provised dark room and to the be- ginnings of the accurate measure ments of two of them. Before any measures could be completed, how. ever, it was necessary to pack up and continue the journey. A hurried ex- animation of the negatives showed them to be of great excellence fin nearly all cases; the dust at WoIlal had injured some of them pictorially, but not in their scientific qualities.
 Director Campbell's original plans had provided time in Australia for the measure of several of the so- called Einstein plates, and the de- duction of preliminary results, but the changes in the transport plans made by the Australian Navy started the expedition north from Freemantle six days earlier and landed it again at Freemantle fifteen days later than anticipated. . ...
 There was nothing to be done but pack the plates up finally at Broome for shipment home with the instru- ments. The glass plates and their packings weigh 500 pounds. The weekly steamer due to leave Free mantle two days after the shipment arrived there failed to run, and in consequence the instruments and plates did not reach Sydney in time to sail home with the astronomers. They are shipped instead via Tahiti, due to arrive at any time.
 The four powerful Einstein cam eras designed and constructed es- pecially for the eclipse used plates seventeen inches square and quar- ter of an inch thick, of plate glass, weighing seven pounds each. There were twelve of these exposed during the period of total eclipse to record the faint stars surrounding the eclipsed sun. The one partially meas ured plate showed eighty-two such stars. The same number of plates were exposed with the instruments to the same group of stars in the night sky last May and June from the Island of Tahiti A comparison of the two series of photographs of the same star group, one without the sun and the other with the sun in the center Of the group, should show whether the suns influence dis plated the star images of September 21 in the manner and extent specified by Einstein This comparison will require several months of measure ment and calculation.
 The suns corona was photo graphed at Wollal with a camera 40 feet in focal lengths, on plates 14x17 inches in size. The negatives are ex- cellent, recording the details of the corona structure with great clear ness. The Lick Observatory lent duplicate camera to the Adelaide University and Observatory for use in Central Australia. The Adelaide mega tives are likewise splendid. Copies of them will be sent to the Lick Ob- servatory, and 1t is hoped that a comparison of the Wollal and Ade- laide photographs will tell us some thing about the changes and motions occurring in the coronal structure in the thirty-five minutes which elapsed between the making of the two series.
 The five spectographs devoted to the photography of the coronal spec trum performed perfectly in the hands of Dr. Moore. It is believed that studies of the photographs, based upon accurate measures; will add to existing knowledge concerning the chemistry and physics of the corona. The governments, the educational institutions and the people of New Zealand and Australia were tremen- dously interested in the California expedition in its eclipse plans and in astronomy in general. Formal recep- tions with addresses of welcome were rendered by the mayors Of all the cities through which it passed, by the universities in four capital cities, by the Royal societies of science, by the governor of one of the states, etc. Formal luncheons were given by Prime Minister Hughes, Senator Pearce and the Cabinet of the Com monwealth Government in the Parlia- ment House, Melbourne, and by Pre- mier Mitchell, his cabinet and the en- tire legislature of Western Australia in Perth. Governor General Admiral Jellicoe, of New Zealand, and Lord
