222 Mr. Corse' s Observations on the 
wards the heads of some younger elephants, I perceived I had 
made a mistake, and that there was not always only one 
grinder in each side of the jaw. This want of uniformity in the 
appearance of the grinders of young elephants, of the same size, 
and nearly of the same age, showed me my mistake, and puzzled 
me a good deal ; nor did I perceive any means whereby I could 
satisfactorily and rationally account for it, till I had carefully 
compared a number of heads, of different ages, with each other. 
To effect this, I immediately began to collect the heads of 
such elephants as died at Tiperah, with the size and qualities 
of which I was perfectly acquainted : in the course of the year 
1796, I procured above thirty heads, and, beginning with the 
youngest of these, I arranged them as nearly as possible accord- 
ing to their respective ages. 
As it may be satisfactory to many members of the Royal So- 
ciety, to learn the means by which I was enabled to collect the 
heads of so many elephants, whose heights and qualities I had 
accurately ascertained, I shall just observe, that between the 
beginning of November, 1795, and the 1st of April, 1796, there 
were four herds of elephants taken in Tiperah. 
Three of these herds were taken under my immediate in- 
spection : the fourth, consisting of about fifty elephants, was 
taken by the Rajah's hunters, but was afterwards so terribly 
neglected, and almost starved to death, that I was requested by 
the Rajah to take them under my management ; to this I con- 
sented, and his servants were ordered to obey implicitly my di- 
rections. In consequence, however, of the former ill treatment 
the elephants had received, above half of them died in the course 
of a few months ; these, with some other casualties, enabled me 
to form the numerous collection above mentioned.
