I find that there were fifteen females and only four males

From the foregoing it will be seen how very difficult it is to obtain the pure breed, even in Siam, and on reference to the Crystal Palace catalogues from the year 1871 until 1887, I find that there were fifteen females and only four males, and some of these were not entire; and I have always understood that the latter were not allowed to be exported, and were only got by those so fortunate as a most extraordinary favour, as the King of Siam is most jealous of keeping the breed entirely in Siam as royal cats.

The one exhibited by Lady Dorothy Nevill (Mrs. Poodle) had three kittens by an English cat; but none showed any trace of the Siamese, being all tabby.

Although Mr. Herbert Young was informed by Mr. Brennand that there is another and a larger breed in Siam, it does not appear that any of these have been imported; nor have we any description of them, either as to colour, size, form, or quality of coat, or whether they resemble the lesser variety in this or any respect, yet it is to be hoped that, ere long, some specimens may be secured for this country.
