12 THE TERMINOLOGY OF SCIENCE 



shed and renewed each year. Professor Lull believes 

 that the Titanothere supplies a fifth distinct type; and 

 that the absence upon the bony core of the grooves and 

 markings indicating the former presence of blood-vessels, 

 such as may be seen on the cores of ox-horns and of the 

 horns of certain extinct reptiles, shows that the Titano- 

 there's cores were not covered, as has been assumed 

 hitherto, by a hollow horny sheath. Moreover, the 

 summit of each bony core is crowned with a rugosity 

 similar to that which supports the horn of a rhinoceros. 

 This leads Professor Lull to conclude that the horns of 

 the Titanothere were simple bony prominences, covered 

 with skin, but tipped with horns of agglutinated hair, like 

 those of the rhinoceros. Altogether the aspect of this 

 creature must have been so ferocious that one would 

 have gone a long way round rather than meet him on 

 a Miocene night. 



I have been taken greatly to task by a correspondent 

 The who complains that, while he derives pleasure 



Terminology from reading my discursive open-air notes, he 

 'cannot bear the barbarous scientific names of 

 things.' Unluckily it is impossible to dispense with them 

 in discussing animate and vegetable nature, owing to the 

 want of precision in English terminology. ' What is the 

 use of giving long Latin names that nobody can remem- 

 ber to creatures and plants which have perfectly intel- 

 ligible English names ? ' What indeed ? if English names 

 were intelligible, or rather, if they were capable of being 

 used with precision. But they are not. For instance,
