account of which appeared in the number of “ Nature” for the 
26th of that month. Again,in March of the following year (1875) 
he gave a short course of lectures at the same institution on 
“ Animal Locomotion,” in one of which he exhibited and explained 
an ingenious model of a boat propelled by a screw, constructed on 
a plan similar to that of the dorsal fin of the pipe-fish.* Another 
dealt with the action of the Horse, giving an account of Marey’s 
experiments with the graphic method on that subject, which was 
then exciting a good deal of attention in England, on account of 
Miss Thompson’s celebrated picture of the “ Roll-Call,” exhibiting 
at that time. 
Garrod commenced his duties as Fullerian Professor in the 
spring of 1876, when he delivered a course of twelve lectures on 
the “Classification of Vertebrate Animals.” In these and his 
subsequent lectures at the same institution, his great mechanical 
ingenuity and extraordinary fertility of resource in devising and 
carrying out experiments, stood him in good stead. For-he was 
enabled, by his numerous models and other simple though ingeni- 
ous contrivances, to illustrate or explain many of the phenomena 
of animal life, in a way that always instructed at the same time 
that it entertained his audiences. These powers, aided by very 
considerable fluency as an extempore speaker, and great facility of 
lucidly explaining even complicated topics to a general audience, 
soon gained him a reputation as an accomplished lecturer. Many 
of those who attended these or his other lectures, must remember 
some of his ingenious models, which were all the more admirable 
often, because of their great simplicity. Such were his arrange- 
ments to show the mechanism of the protrusion and the retraction 
of the claws in the great Carnivora, of the power of rolling-up into 
a ball possessed by the Hedgehog, &c. Other instances of his 
mechanical powers that might be cited were his models of the 
bird’s wing, of the mechanism of the gizzard in birds, and of the 
action of the lips of the Manatee when feeding, exhibited in illus- 
tration of his papers on those subjects before the Zoological 
Society. 
In the summer of 1875 Garrod delivered several of the Davis 
Lectures at the Zoological Gardens, choosing as his subjects the 
various greups of Ruminating Animals, the Camels, Deer, Ante- 
lopes, &c. This group of Mammals had for some time past been
