During the quarter of a century which followed his first contribu- 

 tions to geological science, Mr. Hulke found leisure to apply himself 

 to research in this field, notwithstanding his constantly increasing 

 practice. He did so to so good a purpose that he became a palae- 

 ontologist of no ordinary merit. His knowledge of comparative 

 anatomy, and especially of osteology, enabled him rapidly to grasp 

 the meaning of structures presented by the remains of fossil verte- 

 brates ; and this, combined with a naturally keen perception and a 

 rigid adherence to facts, soon caused his opinion on palaeontological 

 matters to be sought, and held in the highest estimation. 



It was the fossil Reptilia which more especially occupied Mr. Hulke's 

 attention, and his numerous papers on their osteology are a monu- 

 ment to his industry. Many of the fossils which he described were, 

 in part at least, freed from the matrix by his own facile chisel ; and 

 in this mechanical work, as he himself has said, he often found 

 relaxation when his mind was over-wrought by professional anxieties. 



Mr. Hulke's well-earned vacations were often spent at localities of 

 geological interest, more especially with a view to working out the 

 fossils which might be obtained. For this purpose he paid many 

 visits to Brook, in the Isle of Wight, from whence have come many 

 specimens of Wealden Dinosauria ; near here also, at Brixton, was 

 preserved the unique collection of these Wealden reptiles, made by 

 the Rev. W. Fox. For many years Mr. Hulke was the only palaeonto- 

 logist who had free access to this collection ; and he did much good 

 work in bringing to light its hidden treasures, which otherwise 

 remained almost unknown until after the death of their owner, when 

 they were transferred to the British Museum. 



la the year 1868 Mr. Hulke was elected a Fellow of the Geological 

 Society of London, and from that time onwards the pages of the 

 Quarterly Journal of that Society were frequently enriched by his 

 writings. No fewer than six of his papers were published in the two 

 volumes which followed the year of his election, and these with one 

 exception were descriptions of Saurian remains from the Kimmeridge 

 clay of Dorset. Several other papers on reptiles from the same 

 locality appeared in subsequent volumes ; but Mr, Hulke was more 

 particularly interested in the Dinosauria, and many contributions to 

 the osteology of this interesting group of reptiles have appeared in 

 the ' Quarterly Journal ' of the Geological Society, and in the 

 ' Philosophical Transactions ' of the Royal Society. 



Our first knowledge of the cranium of Iguanodon was due to 

 Mr. Hulke's work upon a specimen from the Isle of Wight, which did 

 not include the facial bones, and the affinities of which it was by no 

 means easy to determine. 



In 1873 and 1874 he made additions to our knowledge of the small 

 Wealden Dinosaur, which had been named by Professor Huxley
