INTRODUCTORY ADDRESS.

transformations of this entozoon, accompanied by ecdysis. 
Obviously, I cannot now pass in review the mass of scarcely 
less interesting facts supplied by other correspondents in the 
profession. I must, therefore, only further say, as regards 
equine parasitism, that my acknowledgments are also due to 
Messrs. Storrar, of Chester; to Mr. J. A. Clarke, of March, 
Cambridgeshire ; to Mr. John Gerrard, of Market Deeping, 
Lincolnshire ; to Mr. G. W. Evans, stationed at Aldershot; 
to Mr. John Moore, of Hendon; to Mr. G. Poulton, of Cog- 
geshall, Essex; to Mr. George Goodacre, of Kettering, 
Northamptonshire ; to Mr. W. R. Bryan, of Londonderry ; 
to Mr. T. W. Whitney, of Shepton Mallet; to Mr. William 
Lewis (assisting Mr. Edwards), of St. Alban’s; to Mr. 
Lepper, of Aylesbury; to Mr. A. B Medd; and to a large 
number of other old pupils, amongst whom I must particu¬ 
larise Mr. Coupe, of Stoke-upon-Trent; Mr. George Wil¬ 
kins (whose numerous and valuable contributions have 
enriched our museum), Mr. Awde, Mr. South, Mr. Butters, 
and Mr. J. B. Wolstenholme, who supplied me with 
particulars of a remarkable case of rupture due to parasites. 
One of my most active correspondents all along has beenMr. 
Spooner Hart, of Calcutta, who has forwarded numerous para¬ 
sites taken from solipeds, as well as from other animals both 
wild and domesticated. His “finds” and observations respect¬ 
ing the large mouth maw-worm of the horse are especially 
noteworthy ; but in this connection I must also make my 
acknowledgments to Mr. Charles Percivall, of the 11th 
Hussars, who also forwarded from Umballa, in the Punjab, 
some choice examples of these singular stomach worms, along 
with the tumours which their presence occasions. Staff 
Veterinary-Surgeon Thacker, of the Madras Army, long 
ago sent me a series of flukes from the elephant, and in 
1875 Mr. F. F. Collins, Officiating Principal Veterinary 
Surgeon in the Bengal Army, transmitted a rare “ find ” of 
equine amphistomes. Although these were the first speci¬ 
mens of the genus that I had seen from the horse, it appears 
that Mr. Collins’ discovery was anticipated by Mr. Edward 
Stanley, who five or six years previously had sent similar 
parasites to Professor Simonds. Practically, it is of little 
moment with whom their original discovery rests, but it is 
something to the point to add that there is every reason to 
believe that these entozoa are capable of producing severe 
symptoms in their bearers. These amphistomes, or masuri, 
as they are called in India, have since been found in the 
elephant, and also in man himself; but on this subject I can 
do no more than allude to the fact that I have already made
