Thomas Henry Huxley; A Sketch Of His Life And Work

by Sir P. Chalmers Mitchell

Huxley was only the surgeon on board the Rattlesnake, and his pursuit of natural history was his own affair. There was a special naturalist appointed to the expedition, no doubt chosen because four years earlier, as assistant to Professor Jukes, he had been attached as naturalist to the expedition of the Fly in the same waters. His name was John MacGillivray, and he was the son of an exceedingly able naturalist whose reputation has been overshadowed by the greater names of the middle century. William MacGillivray, the father, sometime professor at the University of Aberdeen, was one of those driven by an almost instinctive desire to the study of nature. In his youth, when he was a poor lad, desiring to see as much as possible of his native land, and above all to visit the great museums and libraries of the south, he walked from Aberdeen to London with no luggage but a copy of Smith's Flora Britannica. He was an ardent botanist, a collector of insects and molluscs, and one of the pioneers in the anatomy of birds. There are many curious allusions in his writings which seem to shew that he too was beginning to doubt the fixity of species, and to guess at the struggle for existence and survival of the fittest which the great Darwin was the first to make a part of the knowledge of the world. It must be confessed that his son John, the companion of Huxley, had little of his father's ability. He was three years older than Huxley, and broke off his medical course at the University of Edinburgh to sail in the Fly. After the return of the Rattlesnake, he was appointed in 1852 as naturalist to H.M.S. Herald, then starting under Captain Denham for surveying work round the shores of South America. He left that ship at Sydney, and after many years' wandering about the southern seas, accounts of which he communicated from time to time to Sydney newspapers, he died in 1867. He was a zealous collector of plants and animals, but apparently cared little for the study of his captures, either in life, in relation to their surroundings, like Darwin, or for the structure of their bodies, like Huxley. The somewhat unpleasing nature of his regard for animals appears in the following story which he himself tells:

"While at dinner off Darnley Island near the Torres Straits, news was brought that Dzum was under the stern in a canoe, shouting out loudly for Dzoka (MacGillivray's native name), and, on going up I found that he had brought off the barit, which after a deal of trouble I struck a bargain for and obtained. It was a very fine specimen of Cuscus Maculatus, quite tame and kept in a large cage of split bamboo. Dzum seemed very unwilling to part with the animal, and repeatedly enjoined me to take great care of it and feed it well, which to please him I promised to do, although I valued it merely for its skin, and was resolved to kill it for that purpose at my first convenience."

On the other hand, MacGillivray paid great attention to native languages, and collected vocabularies of some value. To him was entrusted the task of writing an account of the voyage, and it is from his rather dull pages, brightened by illustrations from Huxley's sketches, that the incidents of the voyage are taken. The references to Huxley in the narrative are slight, and seem to shew that no great intimacy existed between the two young men, the one a naturalist by profession, the other as yet a surgeon, but more devoted to natural history than the naturalist. Such references as occur relate to Huxley's constant occupations on shore, sketching natives and their dwellings, and his apparatus on board for trawling, dredging, and dissecting.

The voyage out was uneventful. The ship touched at Madeira and at Rio de Janeiro, and then crossed the South Atlantic to Simon's Town at the Cape of Good Hope, where the first quantity of treasure was to be landed. There they found the colony distressed by the long continuance of the Kaffir war. Prices for everything were extortionate, and the colonists had no mind for any affairs than their own, so after a short stay the voyagers were glad to set out for the Mauritius. That island, although in the possession of Britain, still retained a strong impress of its French occupation, and the travellers were interested by the mixture of population inhabiting it.[B]

"Passing through the closely packed lines of shipping, and landing as a stranger at Port Louis, perhaps the first thing to engage attention is the strange mixture of nations,—representatives, he might at first be inclined to imagine, of half the countries of the earth. He stares at a coolie from Madras with a breech-cloth and a soldier's jacket, or a stately bearded Moor striking a bargain with a Parsee merchant. A Chinaman with two bundles slung on a bamboo hurries past, jostling a group of young Creole exquisites smoking their cheroots at a corner, and talking of last night's Norma, or the programme of the evening's performance at the Hippodrome in the Champ de Mars. His eye next catches a couple of sailors reeling out of a grogshop, to the amusement of a group of laughing negresses, in white muslin dresses of the latest Parisian fashion, contrasting strongly with a modestly attired Cingalese woman, and an Indian ayah with her young charge. Amidst all this, the French language prevails; and everything more or less pertains of the French character, and an Englishman can scarcely believe that he is in one of the colonies of his own country."

From Mauritius they proceeded to the English-looking colony of Tasmania, and after a few days set out for Sydney, arriving there on July 16th. The surveying officers had tedious work to do there, and Huxley stayed in Sydney for three months. Then, and in the course of three other prolonged stays in that town during the expedition, Huxley entered into the society of the town and became a general favourite. He is still remembered there, and the accompanying illustration[C] is a copy of an original sketch of himself, now in the possession of an Australian lady. He drew it on the fly-leaf of a volume of Lytton's poems and presented it on her birthday to the little daughter of a friend. At Sydney, too, he met and gained the love of the lady, then Miss Henrietta A. Heathorn, who afterwards became his wife.

On October 11th the Rattlesnake sailed northwards to begin the real work of the expedition. The great island of New Guinea, lying to the north of Australia, is separated from it only by the comparatively narrow Torres Straits. Through these lies the natural route for the commerce between Australia and the Northern Hemisphere. The eastward prolongation of New Guinea, and the coast of Queensland, enclose between them a great tropical sea which gradually converges to the Straits. The waters are very tempestuous, and the navigation is made more dangerous by the thousands of coral islands and coral reefs that stud the ocean. Following the shoreline of Queensland, at a distance of from ten to one hundred and fifty miles, and stretching for twelve hundred and fifty miles, is the Great Barrier Reef of Australia, one of the wonders of the world. The shelving floor of the ocean rises nearly to the surface along this line, and vast colonies of coral building creatures have formed their reefs up to the water's edge along the ridge. The turbulent waves scouring over this living mass have carved and moulded it into millions of fantastic islands, sometimes heaping detached masses of dead debris high above the surface of the water. At low tide the most wonderful fields of the animal flowers of the sea are exposed. Some of them form branching systems of hard skeletons like stony trees, the soft, brightly coloured animals dotted over the stems like buds. Others form solid masses; others, again, rounded skull like boulders, or elevations like toadstools. The colours of the skeletons and the animals are vivid scarlets and purples and greens. Sea anemones, shell-fish, and starfish of the most vivid hues are as abundant as the corals. Brilliant fish dart through the blossoms of the marine gardens, and sea birds scream and wheel in the air. The whole region is a paradise for the naturalist. Along the seaward side of the reef the great ocean surges and thunders perpetually. Between it and the shore the quiet channel glows under the tropical skies. It was amid such scenes as these that the Rattlesnake moved for nearly four years in the slow work of taking soundings, fixing the exact position of channels through the outer reef by slow triangular measurements, and generally preparing for the safety of the commerce of all nations. The ship went first up to Port Curtis in Brisbane; then fetched back to Sydney. Its next trip was south to the strait between Tasmania and Australia, then back to Sydney; then again along the Barrier Reef right up to the Torres Straits. After work there, it returned again to Sydney, and then set out for the Louisiade Archipelago, which stretches through the coral sea south-eastward from New Guinea; then again to the Australian shores of the Torres Straits, and finally arrived in Sydney in March, 1850, where the Captain suddenly died, and the ship was ordered to return to England.

Throughout the voyage MacGillivray and Huxley busied themselves with collecting animals on sea and on shore. MacGillivray seems to have taken for his share of the spoil chiefly such animals as provided shells or skins or skeletons suitable for handing over to museums. Huxley occupied himself incessantly with dissecting tools and with the microscope, with results to be described in a later chapter. The better equipped expeditions of modern times were provided with elaborate appliances for bringing up samples of living creatures from all depths of the floor of the ocean, and with complicated towing nets for securing the floating creatures of the surface of the seas. The Rattlesnake naturalists had to content themselves with simple apparatus devised by themselves. At an early period of the voyage attempts were made to take deep soundings, but no bottom was reached at a depth of two thousand four hundred fathoms, and their later work was confined to surface animals or to inshore dredging in shallow waters. They began near Rio.

"None of the ship's boats could be spared, so I [MacGillivray] hired one pulled by four negro slaves who, although strong, active fellows, had great objections to straining their backs at the oar, when the dredge was down. No sieve having been supplied, we were obliged to sift the contents of the dredge through our hands—a tedious and superficial mode of examination. Two days after, Mr. Huxley and I set to work in Botafogo Bay, provided with a wire-gauze meat-cover and a curious machine for cleaning rice; these answered capitally as substitutes for sieves, and enabled us, by a thorough examination of the contents of the dredge, to detect some forty-five species of Mollusca and Radiata, some of which were new to science."

By "new to science" MacGillivray meant no more than that the particular genera and species had not been captured before. Huxley, by his anatomical work, showed many of the most familiar creatures in a light "new to science," by revealing their true structure and relationships.
