As is the case with most of its congeners, there are many varieties of _O. Insleayi_, some of which are much less attractive in their colouring than the one represented in the Plate, while others have much larger flowers, as in the example given in the vignette which is copied from an old woodcut in the Journal of the Horticultural Society. Unfortunately this latter variety has, I greatly fear, been lost to the country, but collectors should endeavour to reintroduce it. I have already referred to Dr. Cauty's success in the treatment of the subject of the present Plate, but his skill and care are equally conspicuous in the management of a miscellaneous collection of Orchids, which he contrives to grow under circumstances such as would have deterred most men from attempting to grow any plants at all. The house in which he lives is in the very centre of Liverpool, and has in its rear a small back court, such as is usually devoted to dustbins and coal-holes, but where Dr. Cauty has found space for three little Orchid-houses of different temperatures in which the Orchids of different climes are perfectly at home. I can really see no reason why in all large towns--in London more especially--Dr. Cauty's example should not be extensively followed, and the luxury of an Orchid-house be thus brought within the reach of many who now consider it quite beyond their grasp.
