Walter Frank Raphael Weldon. XXVIl 
development of the suprarenal bodies was published in the Royal Society 
‘Proceedings.’ On November 3 of the same year, Weldon was elected toa 
Fellowship at St. John’s College, and was shortly afterwards appointed 
University Lecturer in Invertebrate Morphology. About this time he took 
a permanent home at No. 14, Brookside, which soon became a centre for 
Cambridge workers on biology. 
On his return to Cambridge in November, 1884, Weldon had taken up 
again his invertebrate work. His next Memoir, “On Dinophilus gigas,” 
dealt with the anatomy and affinities of Dinophilus, at that time a very 
little known Annelid. 
The next few years of Weldon’s life were more active than ever. He 
had now given up coaching, and as he only needed to be in Cambridge two 
terms of the year, travel and research could occupy the time from the 
beginning of June to January. On May 8, 1885, he gave his first Friday 
evening lecture at the Royal Institution on “ Adaptation to surroundings as 
a factor in Animal Development.” No report of this lecture was published 
in the ‘ Proceedings, but there are those who still remember the impression 
caused by the youthful lecturer of twenty-five years of age. Weldon was 
an adept in lecturing to classes of University students; it brought out all 
his force and enthusiasm as a teacher. As a writer in the ‘limes’ (April 18, 
1906) says: “Seldom is it given to a man to teach as Weldon taught. He 
lectured almost as one inspired. His extreme earnestness was only equalled 
by his lucidity. He awoke enthusiasm even in the dullest, and he had 
the divine gift of compelling interest. In the University Lecture room 
he always impressed his hearers with the importance of his topic. You 
could not listen. to him lecturing on a flame-cell or on the variations in the 
carapace of Pandalus annulicornis without sharing his intense conviction 
of the importance of the matter in hand. He aroused a consciousness in his 
students that things were worth studying for their own sake, apart from 
their examination value.” 
In July, 1886, Weldon crossed to America, and visited the Bahamas 
to collect. From his headquarters in the Bahamas, he went with two friends 
to North Bimini, in the Gulf Stream, and made considerable collections, but 
his published results were confined to “Haplodiscus piger; a new Pelagic 
Organism from the Bahamas,” and a “ Preliminary note on a Balanoglossus 
Larva from the Bahamas.” Working at the Balanoglossus material in 1887, 
he found that his results differed from those reached by Professor Sprengel. 
He accordingly went to Giessen at Easter, and finally handed over to 
Professor Sprengel the whole of his Balanoglossus material. During the Lent 
and May terms he gave a course of lectures on Economic Entomology to the 
forestry students at the Royal Indian Engineering College, Coopers Hill. 
In 1888, the buildings of the Marine Biological Laboratory in Plymouth 
were nearly completed, and to the Marine Biological Association Weldon gave 
both time and sympathy during the rest of his life. His annual visits 
of inspection to their second Laboratory at Lowestoft during the last few
