calved; she then seemed to hecome ill in herself; and after some time, during which it was very doubtful 
whether we should not have lost her, she produced a dead female, which was sent subsequently to the 
British Museum. From the period of parting with that she gradually, but quickly, improved, and took the 
male again August 29 ; which, as the fact has never been since repeated, and she has continued apparently 
in perfect health, we conceive has been effectual, and that she is again in the family-way : it is hoped under 
more favourable auspices than last time, but it must be remembered that she is now by no means a young 
animal. The male is believed to be much younger. He is at times very fierce, and certainly not fit to be 
too much trusted. 
" I am glad to tell you that the report John has brought to me this morning is that the Leuconjw is a 
great deal better, but matters are not a whit further advanced. The period is not, however, so near as you 
appear to suppose, for by what I can learn she is still a fortnight short of what we suppose her full time, 
and I confess I for one have little or no hopes that the produce may be saved, and shall feel well satisfied 
if the mother is ])reserved. She is, however, an old animal, and therefore the chance of her breeding 
again is but small, which makes this young one of much more importance." — May 6, 1845. 
" The Leucoryx is very large, but will yet go some time." — May 16, 1845. 
" I am sorry to say I have more bad news to communicate. Yesterday afternoon John came with a very 
long face, to say that the Leucoryx was very ill ; had taken her supper very well on the previous night ; but 
that mornins: had refused her breakfast, and was since in a very shaky, shivering state, evidently in labour ; 
but he feared the young one was dead, and she could not part with it. We sent for Lyons the farrier, and 
they sat up with the poor lady all night, and she is still much in the same state ; but her eye is clear, and 
this is the only good sign I can make out. They expect to have to sit up with her again tonight ; but I 
fear we must lose the foal even if we can save the dam, which I will hope for. 
" I will give you the latest intelligence of madam before 1 close this tomorrow." 
" Wednesday. — I can add nothing more yet about the Leucoryx. John has been with me, and reports her 
to have been very bad and in much pain in the night, but thinks her now neither better nor worse. He is 
gone to Liverpool for another Veterinarian, and we must remain in longer suspense." — May 21, 1845. 
" I am glad to tell you the Leucoryx continues to progress well, and I do really now begin to have hopes 
of final success ; but even if otherwise, I fear I cannot promise you either the young one or the defunct 
JVomhat, as 1 must keep them for myself." — May 23, 1845. 
"I am glad to be able to continue my good reports of Mrs. Leucoryx, to whom I have been paying my 
first visit since her illness, and I was agreeably surprised by her looks ; in fact, had I not known the cir- 
cumstances, I should have seen no alteration in her since I last saw her just before, i. e. a day or so before, 
her illness. She is certainly much thinner, but that is not to be wondered at, as she ate nothing for five 
days. You may rely on having the calf and Wombat if any one but myself has them." — May 31, 1845. 
" The long-pending event has at last been settled, and the young foetus has been at last obliged to be 
removed from the mother : she is of course unwell, but doing as well as we can expect. The young proved 
to be a female, which adds to my regret. They were obliged to separate the fore-legs to get it away, but 
John assures me that no part whatever has been lost ; but all is sent to you, or will be sent this day, and 1 
hope will reach you in tolerable good state for your object." — June 19, 1845. 
" I wish I could hear that he (Frazer) had secured any A. Leucoryx or females of Addax, as I am much 
afraid we shall lose my old A. Leucoryx female, and have lost the female Addax." — June 30, 1846. 
" Do you know the period of gestation of the Leucoryx ? I heard from John to day, who says the time 
is eight months, as he supposed our lady would produce by the beginning of June 1846." 
" You will be sorry to hear my Leucoryx is dead. I have still a male, but an old animal, for I have had 
him nine years. — She was, I believe, the only female in England." — July 2, 1846. 
" I have just been speaking to John about the extra points you wish to know as to the Addax and Leu- 
coryx. He considers the period of gestation to be in both like the great mass of Antelopes, eight months, 
but he cannot speak so well in this matter about the Leucoryx as of the Addax. The young of the latter 
was at first very diflferent in colour from the adult, being wholly of a light sort of chestnut, and very like a 
young Reindeer in make. It commenced to assume the parental colours at nearly two months. The horns 
are only beginning to copy the parents, and to fall backward from the base. He stated that he had endea- 
voured to measure their length, and I think he said that it was about 12 inches. The old pair change much 
with the season in the shade of their colours ; and he tells me, what I have not noticed myself, that their 
horns also are very different from each other, the male's head not being nearly so good as his wife's : her's 
are much wider apart at the tips ; his, on the contrary, come much closer. I have not noticed this last 
particularly myself, though I have observed the general superiority of her head. 
" Thompson has suggested to me to point your attention to one species, the Harnessed, which differs 
from all other Antelopes in the gestation, or rather subsequently. In the actual gestation it, like the others, 
occupies eight months, but she will receive the male again in another month, and he believes the young 
female will receive him as early as at nine months old." 
" I now send you the memorandum which I lately announced to you relative to Leucoryx and Addax,
