A party of 6 German scientists, who will join the steamer Peiho, arrived in Hong Kong yesterday. They will leave Hong Kong at the end of the week. From German files, we learn that this expedition is being sent out from the Hamburg Scientific Institution. Mr. H. Vogel, the famous artist and painter, accompanies the expedition and will take photographs and cinematograph pictures, and make sketches, and water-colour drawings of such subjects as are desired.
