![[The terms humanised and animalised vaccination will explain themselves, and when I speak of direct vaccination, I mean the use of pure animal vaccine without any other remove.] I have to affim my conviction that it is no longer advisable to use humanised lymph for vaccination, and although aware that I am placing myself in opposition to the views of Jenner, Ceely, Marson, Seaton, and practically of the profession at large, I shall bring facts before you which will, I trust, cause you to support this dictum. The use of humanised lymph should, I think, be in future dis- carded, for these reasons :— I. It is not easy to procure on an emergency. II. It sometimes fails to afford the desired protection. III. It possibly may be thought to be the means of conveying constitutional infection, and so people refuse to be vaccinated. Conversely, calf lymph, properly cultivated, sent out, and used:—■ I. Is available on the briefest possible notice. II. Never fails in preventing Small-pox. III. Is not known to have ever produced any bad symptoms, or transmitted any disease from animal to man ; persons objecting to ordinary vaccination will therefore permit themselves or children to be vaccinated from calves. Let us examine these assertions in detail. I. Every one of my readers,and especially the consultants, must from time to time have experienced some difficulty in procuring thoroughly reliable humanised lymph at a few hours' notice; on the contrary, any quantity that is likely to be required of absolutely fresh and perfect calf lymph can be now sent anywhere from London by next post, on receipt of letter or telegram, as was lately done at midnight, and 300 men were vaccinated by noon next day. II. That children and adults comparatively recently vaccinated with humanised lymph, and some showing good marks, may subse- quently within a few days, months, or years, contract Small-pox is an undoubted fact, probably known to all of us, and certainly demonstrated by the following tables of cases which I have witnessed.](https://iiif.wellcomecollection.org/image/b22273499_0006.jp2/full/800%2C/0/default.jpg)
