December 1853 Port Jackson, N.S.W. wandering in these parts, poor and neglected, though still helplessly busying over Zoological subjects, though old and past active and useful labor in the field of science. As I listened to Wilcox' account the conceit entered my mind that these two men were banished, as it were, from the Scientific world of the Western & Atlantic shores, for the great crime of burdening Zoology with the false though much labored theory which has thrown so much confusion into the subject of its classification and philosophic study. In the afternoon I visited the officers of a new French Clipper Ship now lying in this Port by whom I was treated with the extreme politeness so characteristic of Frenchmen which contrasts so strongly with selfish and often contemptuous silence of English crew when meeting gentlemen having no formal introduction, and with the awkwardness of Americans in a similar situation. This night I speak ashore at the Royal Hotel, where I met two or three gentlemen from Boston, one of whom had resided in Cambridge, close to my fathers residence. December 1853 Port Jackson, N.S.W. 30th Today I had an opportunity of examining the shores of the harbor at a low spring tide. I investigated chiefly at Garden Is. The species of invertebrata obtained were too numerous to catalogue here, (for full descriptions or notices see notes) The Opisthobranchiata were large, and behaved with an activity which was to me quite astonishing. Some of the Acidians were six inches in diameter, with apertures nearly an inch square. Large Chitons and a large Chitonella were very common, as were also Trochi, Parmophori and Tritons of considerable size, and a pretty pink Pleurobranchus. Two species of Echinis lived just below low water mark. Crustaceans were not very abundant. In the evening I went with our Commodore and a few of the officers, to visit and dine with Sir Charles Nicholson, who is probably the chief literary man in the country. He had a splendid library, a Botanic garden etc., and his agreeable manners enabled us, together with the other gentlemen present, to pass a very pleasant evening.
